First, an example of a water distribution network assumed in the embodiment of the present invention will be described. It is assumed that each system or the like described in each embodiment of the present invention targets the water distribution network 50 shown in FIG. In the distribution network 50, water flowing through the river 51 is taken in through the intake facility 52-1 or 52-2. The taken-in water is sent to the water purification plant 53-1 or 53-2 via the pipeline 56, respectively.

Then, the water purified at the water purification plant 53-1 or 53-2 is sent from the demand points 55-1 to 55-4 through one or more pipelines 56. Water is used at each of demand points 55-1 to 55-4.

Each of the demand points 55-1 to 55-4 is a facility or the like that uses water sent through the distribution network 50. Each of the demand points 55-1 to 55-4 includes, for example, general households, offices of companies and the like, shops, factories and the like. That is, the demand point 55 is a set of users (also referred to as consumers) who use the water distributed through the distribution network 50. The number of users existing at each of the demand points 55-1 to 55-4 is not limited to the example shown in FIG. 1, and is not particularly limited.

Further, between each of the water purification plants 53-1 or 53-2 and each of the demand points 55-1 to 55-4, facilities for controlling the state of water distribution including a water supply station and the like are appropriately provided. In the example shown in FIG. 1, two facilities, water supply stations 54-1 and 54-2, are provided. In the example of the water distribution network 50, the water distribution state of a pump station, a valve, or the like composed of, for example, an arbitrary number of pumps is applied to the water purification plant 53-1 or 53-2 or the water supply station 54-1 or 54-2. It is assumed that the equipment to be changed is installed.

In each of the following embodiments, it is assumed that the pump station is a facility composed of an arbitrary number of pumps. The number and types of pumps at the pump station are not particularly limited. Alternatively, the pump station may consist of a single pump.

In the water distribution network 50, the settings in facilities such as the water purification plant 53-1 or 53-2 and the water supply stations 54-1 or 54-2 are set values for operation according to the demand for water at each of the demand points 55 and the like. It is decided. The set values for operation include, for example, the demand for water at each of the demand points 55, the upper and lower limits of the amount of purified water at the water purification plant 53 and the amount of water stored at the water supply station 54, the flow rate fixed in a specific pipeline, and the like. included. The target of the setting value related to the operation is not limited to the above, and other settings related to the distribution network 50 may be included.

Then, equipment such as a pump station provided in a facility such as a water purification plant 53-1 or 53-2, a water supply station 54-1 or 54-2 so that the setting of demand or the like set in the water distribution network 50 is satisfied. A water distribution plan for each of the above is decided.

The water distribution plan is, for example, a plan related to the operation of equipment in the water distribution network 50, such as the amount of water purified at the water purification plant 53 for a certain period of time, the flow rate in each of the pipelines 56 per fixed time, the operation method of the pump station, the operation method of the valve, and the like. including. The water distribution plan is determined based on the above-mentioned operational settings. In other words, the operation method of the pump station specified in the water distribution plan includes the operating time zone, the number of operating units, the combination of pumps to be operated, and the rotation of the pump station for supplying water so that the setting specified by the set value is satisfied. Numbers etc. are included. The valve operation method defined as the water distribution plan includes the valve operation method. That is, the water distribution plan includes designations for various parameters related to the operation of pump stations, valves, and the like.

In the water distribution network 50, a set value is set for a predetermined period such as every day. Then, the designation for the above-mentioned parameters related to the operation of the pump and the like is defined as the water distribution plan so as to satisfy the set value.

The operation of the distribution network 50 based on the formulated water distribution plan is performed by, for example, the water distribution operation system 10 shown in FIG. 3 described later. For example, the water distribution operation system 10 controls the water distribution of the water distribution network 50. The water distribution operation system 10 may have a configuration for formulating a water distribution plan.

First, an embodiment of the present invention will be described. FIG. 2 is a diagram showing an operation support system according to an embodiment of the present invention.

As shown in FIG. 2, the operation support system 100 according to the embodiment of the present invention includes a deviation calculation unit 110, a water distribution range estimation unit 120, and a correction policy derivation unit 130. The divergence calculation unit 110 obtains the difference between the plan and the actual result regarding the state of water distribution in the water distribution network. The water distribution range estimation unit 120 estimates the relationship between the equipment provided in the distribution network and the demand point for each water distribution based on each of the plans and results regarding the state of water distribution for each of the plans and results. The correction policy derivation unit 130 derives a correction policy for the equipment to be corrected and the operation of the equipment based on the difference and the relationship.

The operation support system 100 may further include a configuration for acquiring data used in the above-described components. FIG. 3 shows an example of the operation support system 100 in this case. As shown in FIG. 3, the operation support system 100 includes a water distribution network information acquisition unit 151, a water distribution plan acquisition unit 152, and an actual value acquisition unit 153.

The distribution network information acquisition unit 151 acquires information on the set values related to the operation of the distribution network and the configuration of the distribution network 50. The water distribution plan acquisition unit 152 acquires the water distribution plan in the water distribution network. The actual value acquisition unit 153 acquires the actual value indicating the operating state of the equipment including the pump and the like in the distribution network. The actual value acquisition unit 153 acquires the actual value from the water distribution operation system 10 that operates the water distribution network via a communication network or the like.

Subsequently, each component of the operation support system 100 in the present embodiment will be described. First, the components related to the acquisition of data of the operation support system 100 will be described.

The distribution network information acquisition unit 151 acquires information on the set values related to the operation of the distribution network and the configuration of the distribution network 50. As described above, the set value includes the demand and its forecast at each of the demand points 55 included in the distribution network 50, the upper and lower limit values for operation in each of the facilities provided in the distribution network 50, and the like.

Further, the water distribution network information acquisition unit 151 acquires information on the configuration of the water distribution network 50 in addition to the set values. The configuration of the water distribution network 50 includes the connection relationship of each of the pipelines 56, the connection relationship of the water purification plant 53, the water supply station 54, the demand point 55, etc., and the pump stations provided at the water purification plant 53, the water supply station 54, etc. Equipment placement is included. Information on the performance of these facilities, such as the characteristics of the pumps and valves described above, may be included in the information representing the configuration of the distribution network 50.

The water distribution network information acquisition unit 151 acquires the above-mentioned information via an arbitrary input means such as a keyboard, a mouse, a touch panel, a communication network, or the like. The operation set value acquired by the water distribution network information acquisition unit 151 may be used in the water distribution operation system 10.

The water distribution plan acquisition unit 152 acquires the water distribution plan in the water distribution network. As described above, the water distribution plan is a plan related to the operation of the equipment in the water distribution network 50, which is determined based on the operation set values and the like.

The water distribution plan acquisition unit 152 has a mechanism for formulating a water distribution plan, and the mechanism may acquire the water distribution plan by formulating the water distribution plan. In addition, the water distribution plan acquisition unit 152 may acquire the water distribution plan formulated in the water distribution operation system 10 and other systems via a communication network or the like. When the water distribution plan acquisition unit 152 has a mechanism for determining the water distribution plan, the determined water distribution plan may be appropriately notified to the water distribution operation system 10. The water distribution plan acquisition unit 152 appropriately acquires the water distribution plan every time, for example, derives a revision policy.

The water distribution plan is obtained based on the set value for each of the facilities and the information indicating the configuration of the water distribution network 50. That is, the water distribution plan is required to satisfy the set value for each of the facilities.

In the present embodiment, as a water distribution plan, the water distribution plan acquisition unit 152 mainly describes the amount of water per unit period in each of the pipelines 56 of the water distribution network 50, the operation procedure of the pump station provided in the water distribution network 50, and the operation of valves. Get the procedure etc.

The operation method of the pump station specified in the water distribution plan includes, for example, the operating time zone, the number of operating units, the combination of pumps to be operated, the number of revolutions, etc. of the pump station for supplying water so as to satisfy the setting specified in the set value. Is included. In addition to this, the specification of parameters related to equipment such as valves provided in the water distribution network 50 may be included in the water distribution plan. The water distribution plan acquired by the water distribution plan acquisition unit 152 in the present embodiment is not limited to the above example.

The water distribution plan is preferably defined so as to be an optimized plan based on an arbitrary index. For example, among the water distribution plans that satisfy the set values, the water distribution plan is required so that the power consumption of the equipment in the water distribution network 50 in a certain period is minimized. For example, when the pump station provided in the distribution network 50 is operated according to the water distribution plan, the water distribution plan is required so that the power consumption of the pump station in a certain period is reduced.

The above-mentioned fixed period is appropriately determined according to the demand of the distribution network 50, the operation status, and the like. Further, when the water distribution plan acquisition unit 152 has a mechanism for formulating a water distribution plan, any known method is appropriately used as a specific method for formulating the water distribution plan.

The actual value acquisition unit 153 acquires the actual value related to the operation of the equipment including the pump and the like in the distribution network. The actual value acquisition unit 153 acquires, for example, the actual value regarding the operating state of the equipment in the water distribution network from the water distribution operation system 10 or the like via the communication network or the like. The acquired measured values are used in each element of the operation support system 100 such as the deviation calculation unit 110.

The information acquired by the actual value acquisition unit 153 includes, for example, the amount of water flowing through each point of the pipeline 56, the amount of discharged water in a certain period of time of equipment such as a pump station, and the consumption consumed in a certain period by equipment such as a pump. The amount of power etc. is included. However, the actual values and the like acquired by the actual value acquisition unit 153 are not limited to these. The actual value acquisition unit 153 may acquire other actual values required by the deviation calculation unit 110 or the like.

Subsequently, each element shown in FIG. 2 of the operation support system 100 will be described.

The divergence calculation unit 110 obtains the difference between the plan and the actual result regarding the state of water distribution. That is, the difference between the plan and the actual result regarding the state of water distribution indicates the degree of divergence. Then, the equipment related to the place where the degree of divergence is large is extracted as the equipment in which inefficient operation is performed.

The plan is a value indicating the status of individual equipment when the distribution network 50 is operated based on the water distribution plan obtained by the water distribution plan acquisition unit 152. The plan may include water pressure, flow rate, etc. at each point of the water distribution network 50 when equipment such as a pump station is operated based on the water distribution plan. The value used as a plan may be the value specified in the water distribution plan. In addition, the actual result is a value indicating the actual water distribution status in the water distribution network 50 acquired by the actual value acquisition unit 153. In this embodiment, it is assumed that the ideal value based on the water distribution plan optimized by some standard as described above is used for the plan.

Each of the plans and actual results used in the divergence calculation unit 110 includes, for example, the amount of water at each point of the pipeline 56 of the distribution network 50, the amount of water sent from equipment such as a pump station at a certain time, and the like. However, each of the plan and the actual result is not limited to these, and may include information necessary for extracting equipment in which inefficient operation is performed in the distribution network 50.

The divergence calculation unit 110 obtains the difference between the plan and the actual result for each facility constituting the distribution network. The target equipment includes, for example, a pipeline 56 constituting the water distribution network 50. In this case, for example, the flow rate of water flowing through the pipeline 56 is used as the water distribution state. That is, the divergence calculation unit 110 obtains the difference between the planned flow rate and the actual flow rate for each of the pipelines 56 constituting the water distribution network, for example. The divergence calculation unit 110 may obtain the difference for all the pipelines 56 included in the distribution network 50, or may obtain the difference for the main pipeline 56 among the pipelines 56 included in the distribution network 50. May be good.

In the distribution network 50, each of the facilities may be operated independently. Then, when the condition of the distribution network 50 changes from the plan due to a change in demand or the like, the operation of each facility is changed individually. By changing the operation of each facility individually, the operation of the distribution network 50 may deviate from the ideal plan optimized for any standard as the distribution plan. That is, in the water distribution network 50, there is a possibility that inefficient operation different from the plan will be performed.

Therefore, when deriving the operation correction policy by the operation support system 100, the divergence calculation unit 110 first obtains the divergence between the plan and the actual result. The difference between the plan and the actual result obtained by the divergence calculation unit 110 serves as an index for evaluating whether or not efficient operation is performed according to the plan. That is, the pipeline 56 in which the difference between the plan and the actual result is large, that is, the two are separated from each other, is evaluated as a facility in which inefficient operation is performed.

The divergence calculation unit 110 obtains the difference between the plan and the actual result regarding the state of water distribution by appropriately using a known method. As an example, the divergence calculation unit 110 obtains the sum of the absolute values of the differences between the planned and actual flow rates for each pipeline 56 as a difference in a specific period. The specific period is, for example, one day, but is not limited to this. The specific period may be appropriately determined according to fluctuations in water demand at each point of the distribution network 50 and the like. Further, the deviation calculation unit 110 may obtain the difference by adding the absolute value of the difference between the planned value and the actual value of the flow rate obtained at regular intervals for each pipeline 56. The fixed interval is, for example, every 15 minutes, but is not limited to this.

FIG. 4 shows an example of a planned value and an actual value of the flow rate in each pipeline 56. In the example shown in FIG. 4, the flow rate plans and actual results for the three pipelines 56-1 to 56-3 are shown. In the example shown in FIG. 4, the dotted line indicates the planned flow rate value, and the solid line indicates the actual flow rate value. The vertical arrows shown in the graph of pipeline 56-1 indicate the absolute value of the difference between the planned and actual flow rates. The divergence calculation unit 110 obtains the difference by adding, for example, the absolute value of the difference between the planned flow rate and the actual flow rate as shown by this arrow.

The difference calculation unit 110 may obtain the difference by using other known methods such as cosine similarity and sample correlation. The divergence calculation unit 110 uses these methods to obtain the difference between the plan and the actual result.

The water distribution range estimation unit 120 determines the relationship between the equipment provided in the water distribution network and the demand point regarding each water distribution based on each of the plans or results regarding the water flow and the state of water distribution in the water distribution network. Estimate about. More specifically, the water distribution range estimation unit 120 plans the range of the demand point 55 to be distributed by each of the pump stations 57 provided in the water distribution network 50 based on the plan and actual results of the water flow in each of the pipelines 56. Ask for each of the achievements. The range of facilities of the demand point 55 and other water distribution networks 50 to which the pump station 57 distributes water is referred to as a water distribution range. That is, the water distribution range estimation unit 120 estimates the water distribution range of the pump station 57. The water flow in each of the pipelines 56 includes, for example, the water supply direction and the amount of water, which are the directions of the water flow in each of the pipelines 56.

The water distribution range estimation unit 120 estimates the water distribution range by tracing the water flow in each of the pipelines 56 from the pump station 57 to the demand point 55. An example of the procedure for estimating the water distribution range by the water distribution range estimation unit 120 will be described with reference to FIG. As shown in FIG. 5, each of the water purification plant 53 or the water supply station 54 is provided with pump stations 57-1 to 57-5, respectively. The water distribution range estimation unit 120 estimates the water distribution range of pump stations 57-1 to 57-5, for example.

In each of the drawings after FIG. 5, the numerical value surrounded by the frame attached to each of the pipelines 56 indicates the amount of water in each of the pipelines 56. In the following description, the amount of water represents the amount of water delivered per unit time in the pipeline 56. The value of the amount of water may represent the absolute amount of water, or may be a value representing the relative relationship of the amount of water flowing through the plurality of conduits 56.

Further, in FIG. 5, the direction of each arrow of the pipeline 56 indicates the water supply direction in each pipeline 56. These water supply directions or the amount of water are values obtained by the water distribution plan acquisition unit 152, the actual value acquisition unit 153, or the like, respectively, as either a plan or an actual result. The water distribution range estimation unit 120 estimates the water distribution range in each case based on the water flow obtained as a plan or an actual result. In the examples shown in the drawings from FIG. 5 to the following, the arrows shown in the pipeline 56 connecting the elements of the water distribution network 50 indicate the water supply direction in the pipeline 56.

When estimating the water distribution range by the water distribution range estimation unit 120, it is necessary to consider the water flow at the branch point of the water distribution network 50. The water distribution range estimation unit 120 first estimates the water flow at the branch point. As a branch point to consider, when water flows in from one pipeline and is sent to multiple pipelines, when water flows in from multiple pipelines and is sent to one pipeline, multiple pipes are used. This includes the case where water flows in from the channel and is sent to multiple pipelines.

In the example of FIG. 5, when water flows in from one pipeline at the branch point A and is sent to a plurality of pipelines, water flows in from the plurality of pipelines at the branch point B or D and becomes one pipe. When water is sent to the road, the branch point C corresponds to the case where water flows in from the plurality of pipes and is sent to the plurality of pipes. The water distribution range estimation unit 120 estimates the following water flow for each branch point.

When water flows in from one pipeline and is sent to a plurality of pipelines as in the branch point A, the water distribution range estimation unit 120 determines that the inflowing water depends on the amount of water branched from the branch point A. Estimated to be distributed. At the branch point A, the water distribution range estimation unit 120 sets the water volume of 270 flowing from the pump station 57-4 to the branch point A via the pipeline 56 as the water volume of 120 and 150, and sets the demand points 55-3 and the branch point. It is estimated that they will be distributed to C respectively.

When the water flowing in from the plurality of pipelines 56 is sent to the other one pipeline as in the branch point B, the water distribution range estimation unit 120 tells that all the inflowing water is the other pipe. It is estimated that water will be sent to the road.

At the branch point B, 100 water volumes each flow in from the pump stations 57-2 and 57-3. Therefore, the water distribution range estimation unit 120 estimates that water having a water volume of 200 is sent from the branch point B to the branch point C. Further, the water distribution range estimation unit 120 estimates that the water sent to the branch point C includes 100 each of the water flowing in from the pump stations 57-2 and 57-3.

When water flowing in from a plurality of pipelines 56 is sent to a plurality of pipelines as in the branch point C, the water distribution range estimation unit 120 determines that the water flowing into the branch point C is the amount of water in the pipeline after branching. It is presumed that water is distributed and sent to each pipeline according to the above.

In the example shown in FIG. 5, water having a water volume of 150 flows into the branch point C from the branch point A, and water having a water volume of 200 flows in from the branch point B. The water flowing from the branch point B to the branch point C includes 100 waters flowing from the pump stations 57-2 and 57-3, respectively. Further, in the example shown in FIG. 5, the water flowing into the branch point C is sent from the branch point C to each of the demand point 55-2 and the branch point D. In this case, water having a water amount of 280 is sent from the branch point C to the demand point 55-2, and water having a water amount of 70 is sent from the branch point C to the branch point D. That is, the water flowing into the branch point C is sent to the two pipelines at a ratio of 4: 1.

In this case, the water distribution range estimation unit 120 estimates that the water flowing into the branch point C is distributed to each pipeline at a ratio of 4: 1 and sent. That is, the water distribution range estimation unit 120 receives water from the pump station 57-4 and flows in from the branch point A. It is estimated that the water will be distributed in proportion and sent.

Similarly, in the water distribution range estimation unit 120, the water having a water volume of 200 flowing in from the branch point B is distributed to the demand point 55-2 and the branch point D at a ratio of the water volume of 160 and the water volume of 40, respectively. Presumed to be. Further, the water flowing in from the branch point B includes water sent from the pump stations 57-2 and 57-3 in an amount of 100 each. Therefore, in the water distribution range estimation unit 120, the water of 100 water sent from each of the pump stations 57-2 and 57-3 has a water amount of 80 and a water amount of 20 with respect to the demand point 55-2 and the branch point D, respectively. It is estimated that the water will be distributed and sent in proportions.

That is, in the water distribution range estimation unit 120, the water sent from the pump stations 57-2, 57-3 and 57-4 is 80, respectively, as the water sent from the branch point C to the demand point 55-2. , 80 water volume, and 120 water volume.

Further, when water flowing in from a plurality of pipelines 56 is sent to a plurality of pipelines as in the branch point C, the water distribution range estimation unit 120 determines that the water flowing into the branch point C depends on the inflow ratio. It may be presumed that the water is distributed and sent to each pipeline after branching.

In the example shown in FIG. 5, water having a water volume of 150 flows in from the branch point A, and water having a water volume of 200 flows in from the branch point B. The water flowing in from the branch point B includes 100 waters flowing in from the pump stations 57-2 and 57-3, respectively. That is, in this case, water flows into the branch point C from each of the pump stations 57-2, 57-3 and 57-5 at a ratio of 2: 2: 3.

Therefore, in the water distribution range estimation unit 120, the water flowing in from each of the pump stations 57-2, 57-3 and 57-4 is 2: 2 from the branch point C to each of the demand point 55-2 and the branch point D. It is estimated that the water will be distributed and sent at a ratio of 2: 3.

In the example shown in FIG. 5, water having a water volume of 280 is sent from the branch point C to the demand point 55-2. In the water distribution range estimation unit 120, the water supplied from each of the pump stations 57-2, 57-3 and 57-4 is 80 and 80, respectively, according to the inflow ratio described above. And it is estimated that the amount of water is 120.

Similarly, in the example shown in FIG. 5, water having a water volume of 70 is sent from the branch point C to the branch point D. In the water distribution range estimation unit 120, the water amount 70 and the water sent from each of the pump stations 57-2, 57-3 and 57-4 are 20 and 20 respectively, depending on the inflow ratio described above. And it is estimated that the amount of water is 30. These results are similar to the results estimated as described above, in which the water flowing in from the plurality of pipelines 56 is distributed according to the amount of water in the pipelines 56 after branching.

Further, the branch point D corresponds to the case where the water flowing in from the plurality of pipelines 56 is sent to another one pipeline, similarly to the branch point B. Therefore, the water distribution range estimation unit 120 flows into the water of the amount of water 370 sent from the branch point D to the demand point 55-1 with the water of the amount of water 300 flowing in from the pump station 57-1 and the water of the water amount 300 flowing in from the branch point C. It is estimated that the amount of water is 70.

As described above, the water having the amount of water 70 flowing in from the branch point C includes the water flowing in from each of the pump stations 57-2, 57-3 and 57-5. The water distribution range estimation unit 120 estimates that the water having a water volume of 70 flowing in from the branch point C includes water having a water volume of 20, a water volume of 20, and a water volume of 30, respectively, as described above. That is, the water sent from the branch point D to the demand point 55-1 includes the water sent from the pump stations 57-1, 57-2, 57-3 and 57-4.

The water distribution range estimation unit 120 estimates the water flow at the branch point included in the target water distribution network 50 as described above. Then, the water distribution range estimation unit 120 obtains a demand point 55 to which the water delivered by each of the pump stations 57 reaches, based on the water flow estimated as described above. Then, the water distribution range estimation unit 120 estimates the obtained demand point 55 as the water distribution range. The water distribution range estimation unit 120 may treat the pipeline 56 or its branch point, which is a route to the demand point 55 estimated as the water distribution range, as the water distribution range.

In this way, the water distribution range estimation unit 120 estimates the water distribution range, which is the demand point 55 to which the pump station 57 distributes water, with respect to each of the planned value and the actual value. In addition, the amount of water sent from each of the pump stations 57 is also estimated at the demand point 55 and other facilities that are within the water distribution range. That is, by estimating the water distribution range by the water distribution range estimation unit 120, the relationship between the equipment in the water distribution network 50 such as the pump station 57 and the demand point 55 can be obtained.

In addition, the water distribution ranges of the plurality of pump stations 57 may overlap. That is, each of the demand points 55 may be supplied with water from a plurality of pump stations 57. Each of the pump stations 57 that distributes water to the demand point 55 to which water is supplied from the plurality of pump stations 57 may affect each other's operations in response to a change in demand at the demand point 55 or the like. That is, the water distribution range estimation unit 120 is required to relate each of the plurality of pump stations 57 to each other.

Correction policy The derivation unit 130 has a correction policy regarding the operation of the equipment provided in the water distribution network 50 based on the relationship regarding water distribution such as the difference obtained by the deviation calculation unit 110 and the water distribution range obtained by the water distribution range estimation unit 120. Is derived.

Correction policy The correction policy derived by the out-licensing unit 130 includes the equipment of the distribution network 50 for which the operation should be modified and the content of the modified operation. The revision policy includes the pipeline 56 for which the water volume should be changed, the revised water volume in the pipeline 56, and the like.

As a more detailed example, the correction policy includes a pump station 57 for which the operation state should be corrected, a corrected operation state at the pump station 57, a correction amount of parameters related to the operation of the pump station 57, and the like. Further, the correction policy may include a valve (not shown) whose state should be corrected, a correction of the setting of the water supply direction for the valve, and the like.

The correction policy derivation unit 130 derives the correction policy so as to reduce the difference between the planned value and the actual value based on the difference between the plan and the actual result and the water distribution range. That is, the correction policy derivation unit 130 derives the target whose operation should be revised and the content of the correction of the operation for the target so that the ideal operation according to the plan is performed in the water distribution network 50.

The correction policy derivation unit 130 determines the target for deriving the correction policy based on the magnitude of the difference between the plan and the actual result obtained by the deviation calculation unit 110. For example, the correction policy derivation unit 130 selects a pipeline 56 in which the magnitude of the difference between the plan and the actual result is larger than a predetermined threshold value. Then, the correction policy derivation unit 130 sets the pump station 57 associated with the pipeline 56 as a target for which the operation should be corrected.

Further, the correction policy derivation unit 130 may select a predetermined number of pipelines 56 in the order of the largest difference, and may target the pump station 57 associated with the pipeline 56 as a target for which the operation should be modified. The pump station 57 associated with the pipeline 56 is, for example, a pump station 57 that supplies water to the pipeline 56.

In the above case, equipment such as a plurality of pump stations 57 may be the target for which the operation should be modified. When equipment such as a plurality of pump stations 57 is targeted for revision of operation, the correction policy derivation unit 130 is operated in order from the equipment related to the pipeline 56, for example, where the difference between the plan and the actual result is large. Derive the amendment policy so that it is amended.

When the equipment such as the pump station 57 whose operation should be corrected is determined, the correction policy out-licensing unit 130 requests each equipment to correct the operation. The correction policy derivation unit 130 requests the correction content of the operation so that the difference between the planned and actual flow rate is large, in other words, the amount of water in the pipeline 56 where the planned and actual results deviate approaches the plan.

An example of operational modifications will be further described. The correction policy derivation unit 130 requests the operation correction contents for the target equipment so that the water amount of the pipeline 56 selected in the above procedure approaches the planned value. For example, the correction policy derivation unit 130 requests the correction content such as the operating state of the pump station 57 so as to change the water supply amount of the pump station 57 that supplies water to the pipeline 56.

It is necessary that the above-mentioned operation setting values are satisfied at each of the demand points 55. That is, at each of the demand points 55, it is assumed that the demand amount does not change and is the same even when the operation of the distribution network 50 is changed. Therefore, the correction policy derivation unit 130 requests the correction content of the operation so that the relationship of the following equation (1) is established at each of the demand points 55.

That is, when the correction policy derivation unit 130 derives the correction policy including the correction content that changes the water supply amount of one pump station 57, the water supply amount for each of the demand points 55 becomes the same before and after the correction. Derivation of such a correction policy. Note that in equation (1), q _di represents the amount of water water from the pump station i relative demand point d in the previous modifications, the q _'di, pumping station with respect to the demand point d in the corrected operational It is assumed that the amount of water sent from i is represented.

More specifically, when the correction policy derivation unit 130 derives a correction policy including a correction content that changes the water supply amount of one pump station 57, the water supply amount of another pump station 57 is required. To derive a correction policy that adjusts. The pump station 57 whose total water amount needs to be adjusted due to the change in the total water amount with respect to the one pump station 57 is the pump station 57 whose water distribution range overlaps with that of the one pump station 57.

In this case, the correction policy derivation unit 130 targets the other pump station 57 whose water distribution range overlaps with that of the one pump station 57 described above for further correction of operation. Then, the correction policy derivation unit 130 requests the correction content of the operation for the other pump station 57 whose operation should be corrected. The correction policy derivation unit 130 requests the other pump stations 57 to correct the operation so that the amount of water sent to the demand point 55 does not change before and after the correction of the operation. By deriving the correction policy in this way, it is required to correct the operation in which the relationship of the above-mentioned equation (1) is established.

Hereinafter, with reference to FIGS. 6 to 8, an example of a procedure when the correction policy derivation unit 130 requests the correction content of the operation will be shown. FIG. 6 shows the actual results of the relationship between each of the pump stations 57-1 to 57-3 and its water distribution range. The actual result is acquired by, for example, the actual value acquisition unit 153 or the like.

According to FIG. 6, the actual water distribution range of the pump station 57-1 is the demand points 55-1 and 55-2. The amount of water sent from the pump station to the pipeline 56-1 is 500. Then, water having a water amount of 350 to the demand point 55-1 and a water amount of 150 to the demand point 55-2 is distributed from the pump station 57-1.

Further, in the example shown in FIG. 6, it is shown that water is distributed from the pump station 57-2 to the demand points 55-1, 55-4 and 55-5 via the pipeline 56-2. Similarly, in the example shown in FIG. 6, it is shown that water is distributed from the pump station 57-3 to the demand points 55-1, 55-2 and 55-3 via the pipeline 56-3.

FIG. 7 shows an example of an ideal plan of the relationship between each of the pump stations 57 in the distribution network 50 similar to FIG. 6 and its distribution range. According to FIG. 7, the water distribution range in the example of the ideal plan of the pump station 57-1 is the demand points 55-1 and 55-2, as in the actual value. However, when the pump station is operated according to the ideal plan, the amount of water delivered from the pump station to the pipeline 56-1 is 400. In this case, it is assumed that water having a water amount of 220 to the demand point 55-1 and water having a water amount of 180 to the demand point 55-2 is sent from the pump station 57-1.

Further, in the example shown in FIG. 7, as an example of an ideal plan, it is shown that water is distributed from the pump station 57-2 to the demand points 55-4 and 55-5 via the pipeline 56-2. There is. Similarly, in FIG. 6, as an example of an ideal plan, water is distributed from the pump station 57-3 to the demand points 55-1, 55-2, 55-3 and 55-4 via the pipeline 56-3. It has been shown to be done.

In this example, it is assumed that the difference between the planned and actual amount of water in the pipeline 56-1 is the largest among the pipelines 56-1 to 56-3. Therefore, the correction policy derivation unit 130 derives a correction policy so that the amount of water of the pump station 57-1 to be sent to the pipeline 56-1 is in line with the ideal plan.

That is, the correction policy derivation unit 130 requests the correction content regarding the operation of the pump station 57-1 so that the water amount 400 is sent from the pump station 57-1. More specifically, the amendment policy derivation unit 130 relates to the operation of the pump station 57-1 so that the water having a water amount of 220 is sent to the demand point 55-1 and the water having a water amount of 180 is sent to the demand point 55-2. Ask for corrections.

Correction policy The derivation unit 130 changes the number of pumps operating at the pump station 57-1, the rotation speed of the pumps, etc. so that the above-mentioned amount of water is sent to each of the demand points 55. Ask for. In addition, the correction policy derivation unit 130 may request the correction content regarding the operation of other equipment.

On the other hand, at each of the demand points 55, it is assumed that the demand amount does not change even if the operation of the distribution network 50 is changed. Therefore, the correction policy derivation unit 130 is not limited to the pump station 57-1 but the pump stations 57-2 and 57-3 so that the total amount of water sent to the demand points 55-1 and 55-2 does not change. Derived a correction policy to change the operating state of.

In the examples shown in FIGS. 6 and 7, the amount of water supplied from the pump station 57-1 to the demand point 55-1 is reduced by 130. Further, the amount of water sent from the pump station 57-1 to the demand point 55-2 has increased by 30. Therefore, the correction policy derivation unit 130 derives the correction policy so that, for example, the increase / decrease in the amount of water is evenly distributed to each of the pump stations 57-2 and 57-3. FIG. 8 shows an example of deriving the revision policy.

As shown in FIG. 8, when the water distribution range from each pump station 57 is left as the actual value, the amount of water supplied from the pump stations 57-2 and 57-3 to the demand point 55-1 is increased by 65, respectively. It is expected that the operation will be modified. Further, in this case, it is assumed that the operation is modified to reduce the amount of water sent from the pump station 57-3 to the demand point 55-2 by 30.

That is, the correction policy derivation unit 130 targets the pump stations 57-2 and 57-3 for further correction of operation. Then, the correction policy derivation unit 130 requests the correction contents of the operation such that the amount of water to be sent is changed for each of the pump stations 57-2 and 57-3 as described above.

In the above example, it was assumed that the increase / decrease in the amount of water was evenly distributed to each of the pump stations 57-2 and 57-3. However, the increase or decrease in the amount of water assigned to each of the plurality of pump stations 57 may be different.

For example, different amounts of water may be increased or decreased for each of the plurality of pump stations 57 according to the performance of each of the pump stations 57. Further, the increase / decrease in the amount of water assigned to each of the plurality of pump stations 57 may be changed based on the magnitude of the difference between the plan and the actual result in the pipeline 56 to which each of the pump stations 57 sends water.

Further, when the water distribution range of the pump station 57 differs between the plan and the actual result, the correction policy derivation unit 130 may derive a correction policy for changing the water distribution range. That is, the demand point 55 included in the water distribution range of a certain pump station 57 may change before and after the revision of the operation plan.

In this case, the amendment policy derivation unit 130 derives the amendment policy so as to change the water supply direction of the pipeline 56 included only as a water distribution route with respect to the demand point 55 included either before or after the amendment. .. In other words, the correction policy derivation unit 130 derives the correction policy so as to change the water supply direction of the pipeline 56 which is not included as the water distribution route to the demand point 55 included both before and after the correction. FIG. 9 or FIG. 10 shows an example of deriving the correction policy by the correction policy deriving unit 130 in this case.

FIG. 9 shows an example of deriving the correction policy when the actual water distribution range of the pump station 57 is larger than the plan. That is, FIG. 9 is an example in which the water distribution range by the pump station 57 is reduced.

As shown in the area enclosed in the upper part of FIG. 9, the actual water distribution range of the pump station 57-2 is the demand points 55-1, 55-4 and 55-5. On the other hand, as shown by the area enclosed in the lower part of FIG. 9, in the plan, the water distribution range of the pump station 57-2 is the demand points 55-4 and 55-5. In this case, the correction policy derivation unit 130 derives the correction policy so that the water distribution range of the pump station 57-2 is two of the demand points 55-4 and 55-5.

In this case, the correction policy derivation unit 130 first identifies the pipeline 56 that serves as the water supply route from the pump station 57-2 to the demand point 55-1. Then, the correction policy derivation unit 130 divides the pipeline 56, which is the water supply path, for each branch point.

Subsequently, the correction policy derivation unit 130 sets the water supply route to the demand point (hereinafter, may be referred to as “immutable demand point”) included in both the planned and actual water distribution ranges among the divided pipelines 56. Identify a conduit 56 that is not included and is not a terminal conduit. That is, the correction policy derivation unit 130 identifies the pipeline 56 that is not the terminal pipeline that is the route to the demand point 55 that is included only in the actual results, among the pipelines 56 included in the water distribution range of the pump station 57. The pipe line 56, which is the terminal pipe line, is a pipe line 56 connected to the demand point.

In the example shown in FIG. 9, the pipeline 56 that connects the branch points D and E and is shown thicker than the other pipelines 56 is not included in the water supply route to the constant demand point and is at the end. Corresponds to a non-pipeline. The correction policy derivation unit 130 derives the correction policy so as to change the water supply direction of the pipeline 56.

In this case, the correction policy derivation unit 130 derives, for example, a correction policy for changing the setting of the valve or the like provided in the pipeline 56 described above. That is, the correction policy derivation unit 130 targets the valve provided in the above-mentioned pipeline 56 as a target for which the operation should be corrected. Then, the correction policy derivation unit 130 requests the correction content of the operation related to the control of the valve so as to change the water supply direction in the pipeline 56.

In this case, the correction policy derivation unit 130 derives the correction policy by the above-mentioned procedure or the like so that the amount of water supplied to the demand points 55-4 and 55-5 is in line with the plan together with the change of the water supply direction. do.

FIG. 10 shows a case where the actual water distribution range of the pump station 57 is smaller than planned. That is, FIG. 10 is an example in which the water distribution range by the pump station 57 is increased.

As shown in the area enclosed in the upper part of FIG. 10, in the actual situation, the water distribution range of the pump station 57-3 is the demand points 55-1, 55-2 and 55-3. On the other hand, as shown in the area enclosed by the lower side of FIG. 10, in the plan, the water distribution range of the pump station 57-3 is the demand points 55-1, 55-2, 55-3 and 55-4. Is. In this case, the correction policy derivation unit 130 derives the correction policy so as to expand the water distribution range of the pump station 57-2 to four demand points 55-1, 55-2, 55-3 and 55-4.

The correction policy derivation unit 130 identifies the pipeline 56 that is not included in the water supply route to the invariant demand point and is not the terminal pipeline, as in the above-mentioned example. In the example shown in FIG. 10, similarly to the example shown in FIG. 9, the branch points D and E are connected, and the pipe line 56 shown thicker than the other pipe lines 56 reaches the invariant demand point. Corresponds to the route not included in the water supply route of. The correction policy derivation unit 130 derives the correction policy so as to change the water supply direction of the pipeline 56. The correction policy derivation unit 130 derives, for example, a correction policy for changing the setting regarding the water supply direction of the valve or the like provided in the above-mentioned pipeline 56. Further, the correction policy derivation unit 130 obtains the pipeline 56 whose water supply direction should be changed by specifying the pipeline 56 connected from the original water distribution range to the demand point 55 which is the new water distribution range, and obtains the pipe 56. A modified policy for changing the water supply direction of the road 56 may be derived.

The correction policy derivation unit 130 may derive a correction policy that is different from the procedure described above. The correction policy derivation unit 130 may derive a correction policy different from the policy of changing the operation method of the pump station 57 so that the difference between the plan and the actual result becomes small. The correction policy derivation unit 130 may derive a correction policy for changing the operation method of other equipment provided in the water distribution network 50 so that the difference between the plan and the actual result becomes small.

As described above, in the distribution network 50, each of the facilities may be operated independently. Then, when the condition of the distribution network changes from the plan due to, for example, a change in demand, the operation of each facility is changed individually. Therefore, it may be difficult to change the operational state of the entire distribution network 50 so as to approach the ideal plan.

On the other hand, the correction policy derivation unit 130, for example, as described above, makes a large difference between the plan and the actual result, in other words, the correction content of the operation related to the equipment which is likely to be inefficiently operated. Ask individually. Then, the requested modification contents are individually applied to each facility. The correction policy derivation unit 130 makes it possible to derive an operation correction policy that can be applied to the operation of the actual water distribution network and can improve the operation of the water distribution network 50.

Subsequently, an operation example of the operation support system 100 in the present embodiment will be described with reference to the flowchart shown in FIG.

The processes from steps S101 to S103 are processes for acquiring data necessary for deriving the correction policy. First, the distribution network information acquisition unit 151 acquires information regarding the set value in the distribution network 50 and the configuration of the distribution network 50 (step S101).

Next, the water distribution plan acquisition unit 152 acquires the water distribution plan in the water distribution network 50 (step S102).

Next, the actual value acquisition unit 153 acquires the actual value regarding the operating state of the equipment in the distribution network 50 (step S103).

The processes from steps S104 to S106 are processes in which the operation support system 100 derives a correction policy using the data acquired in steps S101 to S103.

The divergence calculation unit 110 obtains the difference between the plan and the actual result regarding the water distribution state based on the water distribution plan acquired in step S102 and the actual result obtained in step S103 (step S104).

The water distribution range estimation unit 120 estimates the water distribution range of each pump station for each of the plan and the actual result based on the water distribution plan acquired in step S102 and the actual result obtained in step S103 (step S105). ). The water distribution range estimation unit 120 estimates the water distribution range for each of the planned value and the actual value.

The correction policy derivation unit 130 derives an operation correction policy based on the difference between the plan and the actual result regarding the water distribution state obtained in step S104 and the water distribution range obtained in step S105 (step S106). ).

The derived operation modification policy is transmitted to, for example, the water distribution operation system 10 and each facility of the water distribution network 50. Then, in each facility of the water distribution network 50, the water distribution network 50 is operated according to the correction policy.

Further, the operation of the operation support system 100 described above may be repeated. For example, when a modification policy for some facilities of the distribution network 50 is derived by the above operation, the operation of the facilities is modified. Modifications to operations may change the difference between planned and actual. In this case, when the operation support system 100 operates, a correction policy for other equipment is derived. It is expected that the operation results of the water distribution network 50 will approach the plan by repeatedly modifying the operation of the operation support system 100 and the operation of the equipment.

As described above, the operation support system 100 in the present embodiment relates to the operation of the distribution network based on the difference between the plan and the actual result in each of the equipment of the distribution network and the relationship between the equipment and the demand point regarding each water distribution. Derive the revision policy. The amendment policy regarding the operation of the distribution network brain includes the equipment for which the operation should be amended and the contents of the amendment.

As mentioned above, distribution networks generally have complex configurations. In addition, the state of the distribution network changes according to demand and the like. Then, each operation of the water distribution network equipment may be performed individually. Therefore, even if an operation plan that optimizes the operation of the entire distribution network is required, it may be difficult to apply such a plan to actual operation.

In the present embodiment, the operation support system 100 specifies the equipment whose operation should be modified based on, for example, the difference between the optimized ideal plan and the operation. Then, the operation support system 100 derives an operation correction policy for the equipment.

By deriving the amendment policy for each facility, the derived amendment policy can be easily applied to the actual operation even when each operation of the equipment of the distribution network is performed individually. In addition, the correction policy is derived based on, for example, an optimized ideal plan. Therefore, it is expected that the operation of the distribution network will approach the optimized ideal distribution plan by operating the distribution network in accordance with the derived revision policy.

That is, the operation support system 100 makes it possible to derive a correction policy regarding the operation of equipment that makes the operation of the distribution network more efficient.
