First, an example of a water distribution network assumed in each embodiment of the present invention will be described. It is assumed that each device 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 via the pipeline 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 called consumers) who use the water distributed through the water distribution network 50.

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 set in the water purification plant 53-1 or 53-2 or the water supply station 54-1 or 54-2. It is assumed that equipment for changing is provided.

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 be a single pump.

It is determined according to the demand for water in each case. The setting related to the operation of the distribution network 50 including the set water pressure, the flow rate of water, and the like may be referred to as an operation setting value. The setting defined as the operation setting value is not limited to the above, and may include the pressure, flow rate, and the like of the water sent at each point of the pipeline 56.

Then, equipment such as a pump provided in a facility such as a water purification plant 53-1 or 53-2 or a water supply station 54-1 or 54-2 so as to satisfy the pressure, flow rate, etc. of water in the set water distribution network 50. A water distribution plan for each of the above is decided.

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. 2 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 include a configuration used when formulating a water distribution plan.

(First Embodiment)
First, the first embodiment of the present invention will be described. FIG. 2 is a diagram showing an operation support device according to the first embodiment of the present invention. Further, FIG. 3 is a diagram showing another configuration of the operation support device according to the first embodiment of the present invention.

As shown in FIG. 2, the operation support device 100 according to the first embodiment of the present invention includes a deviation degree evaluation unit 110 and a priority determination unit 120. The divergence degree evaluation unit 110 evaluates the degree of divergence between the assumed value and the actual value for each of the facilities based on the assumed value and the actual value regarding the operating state of the equipment in the distribution network. The priority determination unit 120 determines the priority for modifying the operation setting value, which is the setting for the operation in the distribution network, based on the information regarding the deviation and the configuration of the distribution network. The operating state of the equipment includes the power consumption of the equipment or the amount of power consumed in a certain period when the distribution network 50 is operated based on the above-mentioned water distribution plan, the actual pressure and flow rate of water in each of the equipment, etc. Is included.

Further, in addition to the above-mentioned elements, the operation support device 100 may have a configuration for acquiring information used by the above-mentioned deviation degree evaluation unit 110 or priority determination unit 120. As an example, as shown in FIG. 3A, the operation support device 100 may further include a set value acquisition unit 130, a water distribution plan determination unit 140, and an actual value acquisition unit 150.

The setting value acquisition unit 130 acquires the operation setting value. As described above, the operation setting value is a setting related to each operation of the equipment in the distribution network 50. The values determined according to the water demand, such as the water pressure and the flow rate of water at the facilities provided in the water distribution network 50 such as the water purification plant 53 and the water supply station 54, and the pump stations provided by these facilities, are appropriate for the equipment. Relatedly, it is set as an operation setting value.
The operation set value may include the demand at each of the demand points 55 included in the distribution network 50, the predicted value thereof, and the like.

The set value acquisition unit 130 may acquire information regarding the configuration of the water distribution network 50 in addition to the operation set value. 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. Further, the information representing the configuration of the water distribution network 50 may include the upper limit and the lower limit of the flow rate of the pipeline 56 and the amount of water stored in the water supply station 54 and the like. The set value acquisition unit 130 acquires the above-mentioned information via an arbitrary input means such as a keyboard, mouse, or touch panel, a communication network, or the like.

The water distribution plan determination unit 140 obtains a water distribution plan in the water distribution network 50 based on the operation 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 determination unit 140 requests the water distribution plan so that the operation set values for each of the facilities are satisfied. The water distribution plan includes the amount of purified water per unit period at the water purification plant 53, the flow rate at each of the pipelines 56 during a certain period, and the like. In addition to this, the water distribution plan determination unit 140 may request the operation procedure of the pump provided in the water distribution network 50, the operation procedure of the valve, and the like as the water distribution plan.

The water distribution plan determination unit 140 preferably determines an optimized water distribution plan based on an arbitrary index. For example, the water distribution plan determination unit 140 requests a water distribution plan that minimizes the power consumption of the equipment in the water distribution network 50 in a certain period of the water distribution plans that satisfy the operation set values. As a method for formulating a specific water distribution plan by the water distribution plan determination unit 140, any known method is used. In addition, a certain period is appropriately determined according to the demand of the distribution network 50, the operation status, and the like.

The operation method of the pump station specified in the water distribution plan includes, for example, the operating time zone of the pump station where water is sent at the pressure and flow rate specified in the operation set value, the number of operating units, and the combination of pumps to be operated. The number of revolutions etc. is included. The specification of parameters related to the equipment provided in the other distribution network 50 may be included in the distribution plan.

As an example, the water distribution plan determination unit 140 requests a water distribution plan that minimizes the power consumption of the equipment provided in the water distribution network 50. More specifically, the water distribution plan determination unit 140 reduces the power consumption of the pump station in a certain period when the pump station provided in the water distribution network 50 is operated according to the water distribution plan, for example. Ask for a good water distribution plan. When the degree of deviation is evaluated by the degree of deviation evaluation unit 110, for example, an assumed value is determined based on the obtained water distribution plan.

The actual value acquisition unit 150 acquires the actual value regarding the operating state of the equipment including the pump and the like in the distribution network. The actual value acquisition unit 150 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 value is used in the deviation degree evaluation unit 110.

The information acquired by the actual value acquisition unit 150 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 value and the like acquired by the actual value acquisition unit 150 are not limited to these. The actual value acquisition unit 150 may acquire other actual values required by the deviation degree evaluation unit 110 or the priority determination unit 120.

Further, in the present embodiment, as described above, it is assumed that the water distribution operation system 10 controls the water distribution of the water distribution network 50 of the water supply. In this case, the water distribution operation system 10 generally needs information indicating the operation set value and the configuration of the water distribution network 50 when operating the water distribution network 50. In addition, the water distribution operation system 10 may need to formulate a water distribution plan and acquire actual values. Therefore, the water distribution operation system 10 may include elements corresponding to the above-mentioned set value acquisition unit 130, water distribution plan determination unit 140, and actual value acquisition unit 150.

FIG. 3B shows an example in which the water distribution operation system 10 includes a set value acquisition unit 13, a water distribution plan determination unit 14, and an actual value acquisition unit 15. Each of the set value acquisition unit 13, the water distribution plan determination unit 14, and the actual value acquisition unit 15 corresponds to the set value acquisition unit 130, the water distribution plan determination unit 140, and the actual value acquisition unit 150 in FIG. 3 (A), respectively.

In the configuration of the water distribution operation system 10 shown in FIG. 3B, the set value acquisition unit 13 and the water distribution plan determination unit 14 are mainly used for acquiring the operation set value and formulating the water distribution plan. Further, in the configuration of the water distribution operation system 10 shown in FIG. 3B, the actual value acquisition unit 15 is mainly used when acquiring the water distribution status in the water distribution network 50.

In the configuration shown in FIG. 3B, the deviation degree evaluation unit 110 or the priority determination unit 120 of the operation support device 100 may use the values acquired or determined by each element of the water distribution operation system 10 described above. ..

In the examples shown in FIGS. 3A and 3B, the water distribution operation system 10 may include other elements (not shown) related to water distribution control in the water distribution network 50. In the example shown in FIG. 3B, the water distribution operation system 10 may have an operation support device 100.

Subsequently, the deviation degree evaluation unit 110 and the priority determination unit 120, which are the main components of the operation support device 100 according to the first embodiment of the present invention, will be described.

The divergence degree evaluation unit 110 evaluates the degree of divergence between the assumed value and the actual value for each of the facilities based on the assumed value and the actual value regarding the operating state of the equipment such as the pump provided in each facility of the distribution network 50. do. The operating state indicates, for example, the state and value of each of the facilities of the water distribution network 50 when the water distribution network 50 is operated according to the water distribution plan.

The divergence degree evaluation unit 110 targets the power consumption of the equipment provided in each facility of the distribution network 50 in a certain period as an example of the operating state. The equipment includes a pump. That is, the divergence degree evaluation unit 110 evaluates, for example, the degree of divergence between the assumed value and the actual value regarding the power consumption of the pumps provided in each facility of the distribution network 50 in a certain period. In the following description, the degree of dissociation described above may be referred to as "dissociation degree" or simply "dissociation". In this case, the deviation degree evaluation unit 110 may evaluate the deviation between the assumed value and the actual value with respect to the operating state of other equipment that may affect the power consumption of the pump in a certain period.

The assumed value is a value related to the state of operation assumed when the distribution network 50 is operated according to, for example, a water distribution plan obtained in advance. Assumed values are assumed, for example, in units of a certain period. The divergence degree evaluation unit 110 obtains an estimated value for the target equipment based on the water distribution plan obtained by the water distribution plan determination unit 140 or the water distribution plan determination unit 14 provided in the water distribution operation system 10. The divergence degree evaluation unit 110 may acquire the assumed value obtained based on the water distribution plan by the water distribution plan determination unit 140 or the water distribution plan determination unit 14 provided in the water distribution operation system 10.

The water distribution plan that serves as the reference for the assumed value is also a plan that has been obtained in advance by the water distribution plan determination unit 140 and the like. Further, when the demand for water at each of the demand points 55 of the distribution network 50 changes, the deviation degree evaluation unit 110 uses the water distribution plan newly obtained by the water distribution plan determination unit 140 or the like according to the change in demand as a reference. You may use the assumed value of.

The actual value is a value related to the operating state of each of the facilities when water is actually distributed in the water distribution network 50. As the actual value, a value related to the operation state acquired by the actual value acquisition unit 150, the actual value acquisition unit 15 included in the water distribution operation system 10, and the like is used.

An example of evaluation of the degree of dissociation by the dissociation degree evaluation unit 110 will be described with reference to FIGS. 4A and 4B. 4 (A) and 4 (B) are graphs showing the relationship between the flow rate of the pump station and the power consumption in a certain period. In each of FIGS. 4A and 4B, the horizontal axis represents the flow rate of the pump station, and the vertical axis represents the power consumption of the pump in a certain period. In the examples of FIGS. 4A and 4B, for example, 15 minutes is assumed as a fixed period. The graph of FIG. 4 is obtained for each pump station provided in, for example, the water distribution network 50. In the graphs shown in FIGS. 4A and 4B, the pump station is simply referred to as a pump.

In the graph of FIG. 4 (A), the solid line indicates the flow rate and consumption of the pump station assumed for a certain period when the pump station is operated according to the water distribution plan obtained by, for example, the water distribution plan determination unit 140 or the like. An example of the relationship with the amount of electric power is shown. This relationship is required for each pump station that is the target of the water distribution plan, for example. The deviation degree evaluation unit 110 sets the solid line in FIG. 4A as an assumed value of the relationship between the flow rate and the power consumption in a certain period for each of the pumps provided in the distribution network 50.

Further, in the graph of FIG. 4A, each of the square marks is a value actually obtained from each of the pump stations provided in the water distribution network 50 via, for example, the actual value acquisition unit 150 or the like. The deviation degree evaluation unit 110 sets each of the squares in FIG. 4A as the actual value of the relationship between the flow rate of each of the pumps provided in the distribution network 50 and the electric energy consumption in a certain period.

The actual value represents a value actually obtained in the operation of the distribution network 50. The actual value is obtained in units of a fixed period such as 15 minutes. The fixed period is determined according to, for example, the length of the situation in which the demand is expected to be substantially constant. The graph of FIG. 4A shows, for example, assumed values and actual values in a 15-minute period such as from 8:00 to 8:15.

When the equipment of the distribution network 50 is operated according to the water distribution plan obtained by the water distribution plan determination unit 140 or the like, the relationship between the flow rate of the pump station and the power consumption is approximately in line with the assumed value. .. However, in response to changes in conditions such as changes in water demand, specifications for parameters and the like related to the operation of equipment provided in the distribution network 50 including the pump station may be changed for each site.

In addition, the operating status of one facility may be affected by the operating status of another facility. As a result, the relationship between the flow rate of the pump and the amount of power consumption in a certain period may deviate from the assumed value, and a large amount of power may be consumed as compared with the assumed value.

As shown in FIG. 4A, in most of the actual values, the relationship between the flow rate and the power consumption is generally in line with the assumed value. However, with respect to the actual value included in the area surrounded by the dotted line in the figure, the power consumption with respect to the flow rate is larger than the assumed value. That is, it is considered that the pump stations corresponding to these consume a large amount of electric power as compared with the assumed value.

As an example of the evaluation of the degree of divergence, the divergence degree evaluation unit 110 obtains the coordinate distance between the above-mentioned actual value and the assumed value as shown in FIG. 4 (B). The deviation degree evaluation unit 110 obtains, for example, the coordinated distance between the actual value and the assumed value for a certain period. The fixed period is, for example, a period of 15 minutes as described above. In the graph shown in FIG. 4 (B), the assumed value and the actually measured value are represented in the same manner as the graph shown in FIG. 4 (A). Further, in the graph shown in FIG. 4 (B), the triangular marks represent individual assumed values for pumps whose actually measured values deviate from the predicted values.

In the example shown in FIG. 4B, the deviation degree evaluation unit 110 evaluates the deviation degree based on, for example, the coordinate distance between the assumed value and the actually measured value as described above. For example, the divergence evaluation unit 110 determines, for each of the equipment such as a pump station, an assumed value in a certain period indicated by a triangular mark and an actually measured value in a certain period indicated by a square mark. Find the distance on the coordinates. The divergence degree evaluation unit 110 obtains the sum of the coordinated distances obtained at regular intervals as described above in a predetermined period such as one day. Then, the divergence degree evaluation unit 110 sets the obtained sum as the divergence degree for each of the facilities provided in the water distribution network 50 such as a pump.

The divergence degree evaluation unit 110 may use another index relating to the difference between the actual value and the assumed value as the divergence degree. Further, for each of the assumed value and the actual value, the period for which the distance is to be calculated and the period for which the difference is calculated for the degree of dissociation are not limited to the above examples. Further, the period of the predetermined period described above is not limited to one day or the like, and may be different. Each of the above-mentioned periods may be determined according to the state of the distribution network 50 including changes in the demand of the distribution network 50 and the like.

Further, when the actual value of the power consumption in each facility of the water distribution network 50 in a certain period is smaller than the assumed value, it is assumed that no particular problem will occur. Therefore, when the divergence degree evaluation unit 110 determines the divergence degree with respect to the power consumption amount, the divergence degree is increased so that the divergence degree becomes large when the actual value of the power consumption amount in a certain period is larger than the assumed value. May be determined. When the actual value of the power consumption in a certain period is smaller than the assumed value, the deviation degree evaluation unit 110 may determine the degree of deviation so that the actual value is treated as being in line with the assumed value.

The priority determination unit 120 determines the priority regarding the correction of the operation set value in the water distribution network 50 based on the degree of dissociation evaluated by the dissociation degree evaluation unit 110 and the information on the interrelationship described later in the water distribution network 50.

As described above, the deviation degree evaluation unit 110 evaluates the deviation degree between the assumed value and the actual value. If the degree of divergence is large, for example, there is a possibility that a larger amount of power is consumed than expected. In this case, it is preferable that the operation setting value of the equipment provided in the distribution network 50 is changed based on the degree of dissociation, for example, so that the power consumption in a certain period is reduced. Then, when changing the operation setting value, it is assumed that the operation setting value for the equipment having a large degree of deviation is selected as the target of the change.

However, the distribution network 50 generally has a complex network structure. If the designation of the operation method, etc. of the equipment is changed so that the operation state of the equipment in one water distribution network 50 such as a pump is changed, the operation state of other equipment may be affected by the change. .. In this case, if the designation of the operation method, etc. for the equipment is changed so that the power consumption of the equipment with a large degree of divergence decreases in a certain period, the power consumption of other equipment in the certain period increases. There is a possibility of doing so.

For example, if the operating state is changed so as to reduce the power consumption of a facility having a large degree of divergence over a certain period of time, the power consumption required for the operation of the entire distribution network 50 may increase. be. Therefore, when the operation setting value is changed based on the equipment such as a pump having a large degree of deviation, it may be necessary to consider other equipment affected by the change in the operating state of the equipment.

In the following description, equipment whose degree of dissociation satisfies a predetermined condition and equipment affected by a change in the operating state of the equipment may be collectively referred to as "equipment that interacts". In addition, the relationship between each of the facilities that interact with each other may be referred to as an interaction. That is, the equipments that are in a mutual relationship are the equipments that can influence each other's operating conditions.

First, the priority determination unit 120 extracts equipment whose degree of dissociation satisfies a predetermined condition and equipment which is affected by a change in the operating state of the equipment. That is, the priority determination unit 120 extracts the equipment whose degree of deviation satisfies the predetermined condition and the operation setting value related to the group of equipment interrelated with the equipment as the target for determining the priority.

The above-mentioned interrelated equipment is, for example, equipment located upstream or downstream of equipment having a degree of divergence satisfying a predetermined condition in a distribution network 50 or the like. These facilities are, for example, pump stations, but may be other types of equipment such as valves that affect water distribution, and the types of equipment are not limited. For the positional relationship of the upstream or downstream, the configuration of the water distribution network 50, the flow of water according to the water distribution plan obtained by the water distribution plan determination unit 140, etc., the measured value acquired by the actual value acquisition unit 150, etc. are used. Determined based on the flow of water obtained.

The priority determination unit 120 obtains information necessary for identifying equipment having an interrelationship, that is, information on the interrelationship in the water distribution network 50, such as a set value acquisition unit 130, a water distribution plan determination unit 140, and an actual value acquisition unit 150. Obtain from as appropriate. The information required for identifying the equipment that interacts includes, for example, information on the configuration of the distribution network 50 and information on the flow of water in the distribution network 50.

Further, the priority determination unit 120 may acquire information on the mutual relationship from the set value acquisition unit 13, the water distribution plan determination unit 14, the actual value acquisition unit 150, and the like included in the water distribution operation system 10. Further, the priority determination unit 120 may acquire from the deviation degree evaluation unit 110 and use information that can be used as information on the mutual relationship among the information acquired by the deviation degree evaluation unit 110.

The equipment in which the degree of dissociation satisfies a predetermined condition is, for example, the equipment having the largest degree of dissociation. Alternatively, the equipment whose degree of dissociation satisfies a predetermined condition may be equipment whose degree of dissociation is larger than a predetermined threshold value. When there are a plurality of facilities whose degree of dissociation satisfies a predetermined condition, the priority determination unit 120 extracts, for example, facilities that are mutually related to each of the plurality of facilities.

The priority determination unit 120 prioritizes the operation setting values related to these interrelated equipments based on the degree of divergence for each of the interrelated equipments and the number of the interrelated equipments. stipulate. For example, the priority determination unit 120 determines the sum of the degree of dissociation obtained for each of the equipment in which the degree of dissociation satisfies a predetermined condition and the equipment in a group of interrelated facilities, for the number of these equipments. The priority is determined based on the magnitude of the value obtained by dividing by the sum.

That is, the priority determination unit 120 first extracts the equipment related to the operation set value to be the target of the priority determination based on the magnitude of the deviation degree. In this case, not only the equipment satisfying the predetermined conditions such as the largest degree of divergence, but also a group of equipment having a mutual relationship is extracted. Then, the priority determination unit 120 determines the priority based on the sum of the deviation degrees obtained for each of the group of interrelated equipment. By doing so, it is more likely that the operational settings associated with a group of interrelated equipment, including equipment with a large degree of divergence, will be given higher priority. Therefore, it is easy to avoid an increase in power consumption in the operation of the entire distribution network 50, which may occur when only the operation setting value related to the equipment having a large degree of deviation is changed.

On the other hand, when the priority is determined based on the sum of the divergence degrees described above, the sum of the divergence degrees may become a large value when the number of the target group of interrelated equipment is large. .. Then, there is a possibility that a high priority is set for the operation setting values related to such a group of equipment. However, if the number of facilities that are interrelated is large, a large amount of man-hours may be required to change the operation setting value or change the operation status based on the change in the water distribution plan due to the change in the operation setting value. There is. Therefore, when operating the distribution network 50, it is preferable that a large effect can be obtained by changing the operating state for a small number of facilities.

Therefore, the priority determination unit 120 determines the sum of the deviation degrees with respect to the equipment related to the operation setting values having a large deviation degree and the operation setting values related to each of the equipments interrelated with the equipment, for the number of these equipments. The priority is determined based on the value obtained by dividing by the sum. For example, the priority determination unit 120 determines the priority in the order of the magnitudes of the values obtained as described above. By doing so, when determining the priority, both the effect of improvement by changing the operation setting value and the time and effort required for improvement are taken into consideration.

The priority determination unit 120 may determine the priority by a different procedure. The priority determination unit 120 may determine the priority based on either the degree of divergence from each of the interacting equipment or the number of interacting equipment. Further, the method used by the priority determination unit 120 to calculate the priority may be different from the above-mentioned example. For example, when the effort for changing the setting is small, the priority determination unit 120 may give a high priority to the operation setting value related to the group of equipment having the largest sum of deviations. Alternatively, the priority determination unit 120 may give a high priority to the operation setting values related to the group of equipment including the equipment having the largest degree of divergence.

In addition, the priority determination unit 120 may determine the priority for all the operation setting values, and the priority is given to the operation setting values related to some facilities whose operation status needs to be changed. May be determined. When the priority determination unit 120 determines the priority for the operation setting values related to some equipment, for example, it is related to the equipment that is operated in an appropriate state and does not need to change the operation state. The operation setting value may be excluded from the target of the priority determination.

With reference to FIG. 5, an example of equipment affected by a change in the operation setting value related to one equipment, that is, equipment having a mutual relationship will be described. In the example of the distribution network 60 shown in FIG. 5, it is assumed that the water purified at the water purification plant 63 is supplied to each of the demand points 65-1 to 65-7 via the pipeline 600. Water supply stations 64-1 to 64-4 are provided in the pipeline 600.

In the water distribution network 60 shown in FIG. 5, each of the water purification plant 63, the water supply station 64, and the demand point 65 is a facility of the same type as the water purification plant 53, the water supply station 54, and the demand point 55 shown in FIG. Further, it is assumed that each of the water purification plant 63, the water supply station 64, and the demand point 65 is provided with at least a pump station. Further, in FIG. 5, the arrows attached to each of the pipelines 600 indicate the flow of water at each point. The water flow is determined based on the water distribution plan obtained by the water distribution plan determination unit 140 and the like, the actual measurement value acquired by the actual value acquisition unit 150 and the like, and the like.

In this example, it is assumed that the deviation degree evaluation unit 110 evaluates that the deviation degree is large with respect to the pump station provided in the water supply station 64-4. There is a water supply station 64-1 in the water distribution route from the water purification plant 63 to the water supply station 64-4. In this case, the priority determination unit 120 extracts these equipments as equipments that interact with each other by changing the operating state of the pump provided in the water supply station 64-4. That is, in this example, the pump stations provided in the water supply station 64-4, the water supply station 64-1 and the water purification plant 63 are interrelated equipment.

Both the water purification plant 63 and the water supply station 64-1 exist on the upstream side of the water distribution route to the water supply station 64-4. However, if there is equipment equipped with a pump station or the like in the route on the downstream side of the water supply station 64-4, the priority determination unit 120 is the equipment located on the downstream side of the water supply station 64-4 as described above. May be extracted as interrelated equipment.

The priority determination unit 120 determines the priority based on the sum of the deviations of the water supply station 64-4, the water purification plant 63 and the water supply station 64-1 divided by 3, which is the number of facilities. When there are other groups of interrelated equipment in the distribution network 60, a value obtained by dividing the sum of the degrees of divergence by the number of equipment is obtained for those groups of equipment. Then, for example, the priority determination unit 120 determines the priority based on the magnitude of the obtained value.

When the priority is determined, the priority is notified to the water distribution operation system 10 and the managers of related facilities. Then, the operation setting value in the water distribution network 50 is updated according to the magnitude of the priority and the like. When the operation set value is updated, a new water distribution plan is requested by the water distribution plan determination unit 14 and the like. Then, based on the new water distribution plan requested, the parameters and the like of the equipment provided in the water distribution network 50 are appropriately modified by the equipment manager and the like.

Subsequently, the operation of the operation support device 100 according to the first embodiment of the present invention will be described with reference to the flowchart shown in FIG.

First, the divergence degree evaluation unit 110 acquires information necessary for evaluating the divergence degree (step S101). In step S101, the deviation degree evaluation unit 110 acquires at least the assumed value and the actual value regarding the operating state of the equipment in the water distribution network 50 described above.

Next, the divergence degree evaluation unit 110 evaluates the divergence degree using the information acquired in step S101 (step S102).

Next, the priority determination unit 120 determines the priority regarding the correction of the operation set value based on the degree of deviation obtained in step S102 and the information regarding the mutual relationship (step S103). In step S103, the priority determination unit 120 appropriately acquires information on the mutual relationship from the set value acquisition unit 130, the water distribution plan determination unit 140, the actual value acquisition unit 150, and the like. Further, the priority determination unit 120 may use the information regarding the configuration of the water distribution network 50 or the like acquired in step S101 as the information regarding the mutual relationship.

The operation support device 100 may repeat the operations from steps S101 to S103 periodically or in response to changes in demand and the like.

As described above, the operation support device 100 according to the first embodiment of the present invention determines the priority regarding the correction of the operation set value based on the degree of deviation regarding the operation state. When the priority determination unit 120 determines the priority, the configuration of the distribution network is taken into consideration. That is, when determining the priority, the mutual relationship of the equipment when the operation setting value in the distribution network 50 or the like is changed is taken into consideration. Therefore, for example, it is possible to determine the priority so as to avoid an increase in the power consumption of the entire distribution network 50.

Therefore, the operation support device 100 in the present embodiment enables efficient operation of the water distribution network.

(Second embodiment)
Next, a second embodiment of the present invention will be described. FIG. 7 is a diagram showing an operation support device according to a second embodiment of the present invention. Further, FIG. 8 is a diagram showing another configuration of the operation support device according to the second embodiment of the present invention.

As shown in FIG. 7, the operation support device 200 according to the second embodiment of the present invention includes a deviation degree evaluation unit 110, a priority determination unit 120, and a set value update unit 260. The divergence degree evaluation unit 110 and the priority determination unit 120 are elements similar to the elements with the same reference numerals provided in the operation support device 100 in the first embodiment. The setting value update unit 260 updates the operation setting value related to each facility based on the priority for each facility and the operation history of the distribution network.

Further, the operation support device 200 in the present embodiment may include an operation history storage unit 261. The operation history storage unit 261 stores the operation history in the water distribution network 50.

That is, the operation support device 200 in the present embodiment is different from the operation support device 100 in the first embodiment in that at least the set value update unit 260 is further provided.

The operation support device 200 in the present embodiment may further include a set value acquisition unit 130, a water distribution plan determination unit 140, and an actual value acquisition unit 150, similarly to the operation support device 100 in the first embodiment. .. FIG. 8A is a diagram showing a configuration when the operation support device 200 includes these elements.

Further, when the water distribution operation system 10 includes elements corresponding to the water distribution plan determination unit 140 and the actual value acquisition unit 150, the operation support device 100 may use the values acquired or determined by these elements.

FIG. 8B shows an example in which the water distribution operation system 10 includes a set value acquisition unit 13, a water distribution plan determination unit 14, and an actual value acquisition unit 15. Similar to the example in the first embodiment, each of the set value acquisition unit 13, the water distribution plan determination unit 14, and the actual value acquisition unit 15 has the set value acquisition unit 130, the water distribution plan determination unit 140, and the water distribution plan determination unit 140 in FIG. 8A. Corresponds to the actual value acquisition unit 150, respectively.

Subsequently, among the components of the operation support device 200 according to the second embodiment of the present invention, the elements not included in the operation support device 100 according to the first embodiment will be described.

The setting value updating unit 260 sets the operation setting value related to each of the facilities provided in the water distribution network 50 or the like based on the priority determined by the priority determination unit 120 and the operation history in the water distribution network 50. Perform the processing required for updating.

The operation history includes a history of past operations of the equipment in the water distribution network 50, such as operation contents for equipment such as a pump station based on a water distribution plan, a change in demand in the water distribution network 50, and the like. The processing required for updating the operation setting value includes, for example, determination and output of a candidate for the operation setting value to be updated or a specific value of the operation setting value, the operation setting value in the water distribution operation system 10 and the like, and the operation setting. Includes updates such as water distribution plans that are determined based on the values.

In the present embodiment, as described above, it is assumed that the operation support device 200 includes the operation history storage unit 261 as an example. The operation history storage unit 261 stores the history related to the operation of the equipment in the water distribution network 50. The operation support device 200 may acquire the operation history of the water distribution network 50 from the water distribution operation system 10 or the like as necessary via a communication network or the like.

As an example, the operation history storage unit 261 is configured as a knowledge base in which the operation history is patterned. In this case, the operation history storage unit 261 classifies and stores the history of changes in the operation setting values when the degree of deviation is large from a plurality of viewpoints.
For example, the history of changes in the operation setting value depends on the equipment related to the operation setting value, the magnitude of the deviation related to the equipment, and the changed value or change of the water distribution plan changed based on the change of the operation setting value. It is stored in the operation history storage unit 261 according to the result and the like. Further, the history of changes in the operation setting values may be classified according to demand, date and time, time zone, etc. and stored in the operation history storage unit 261.

In addition, the history of changes in the above-mentioned operation setting values may be accompanied by information on the appropriateness of countermeasures according to the status of changes in power consumption due to the changes.

For example, if the power consumption consumed in the entire operation of the distribution network 50 is reduced due to the change in the operation setting value, it is appropriate to take appropriate measures against the history of the change in the operation setting value. Information is attached. In addition, when the power consumption consumed in the entire operation of the distribution network 50 increases due to the change in the operation setting value, it is appropriate for the history of the change in the operation setting value. Information that it is not a countermeasure may be attached.

As an example, the setting value updating unit 260 determines the operation setting value to be updated and the candidate of the specific value of the operation setting value as follows.

The setting value updating unit 260 acquires the history of changes in the operation setting values related to the equipment given the high priority by referring to the operation history storage unit 261 or the like. In this case, it is preferable that the set value updating unit 260 refers to the history related to the demand, time zone, etc. related to the equipment to which the high priority is given. The number of histories acquired by the set value update unit 260 is not particularly limited.

Then, the setting value updating unit 260 is updated with the setting update value to be updated based on the history when, for example, the magnitude of the deviation degree , the demand, the time zone, etc. are approximate and appropriate measures are taken. Determine the value of the setting update value. For example, the setting value updating unit 260 uses the updated operation setting value included in the history when appropriate measures are taken as the value of the setting update value to be updated or the value of the setting update value to be updated.

The setting update value to be updated is not limited to the setting update value related to the equipment having a high degree of deviation or priority. It is conceivable that there may be equipment with a large priority or divergence due to the operating status of the equipment that is adjacent to the equipment with a high priority and is not considered by the priority determination unit 120. Therefore, the setting update value to be updated may include a setting update value related to the equipment adjacent to the equipment having a high priority and not considered by the priority determination unit 120.

Further, the candidate of the setting update value to be updated and the specific value of the setting update value to be updated is not limited to one. For example, when a plurality of histories relating to the case where appropriate measures are taken are stored, the setting value update unit 260 sets the setting update value to be updated and the setting to be updated based on each of the plurality of histories. Candidates for the value of the update value may be determined.

Further, the history used by the setting value updating unit 260 is not limited to the history when appropriate measures are taken. For example, statistical values such as average values for past operation history related to equipment given a high priority may be used.

When a candidate for the setting update value to be updated or a specific value of the setting update value to be updated is determined, the setting value update unit 260 outputs the determined candidate or plans the water distribution in the distribution network 50 based on the determined candidate. Update etc.

As the output of the determined candidate, the set value updating unit 260 controls, for example, to display it on an arbitrary type of display or the like. The setting value updating unit 260 may be controlled so that the determined candidate is output to a display or the like provided in another device connected via the communication network.

The operator of the equipment provided in the water distribution operation system 10 or the water distribution network 50 appropriately determines a new operation setting value for the water distribution network 50 based on, for example, the result of the output setting value update unit 260.

Further, the water distribution plan in the water distribution operation system 10 and the like is updated as follows, for example. In this case, the set value updating unit 260 inputs a new operation set value to the water distribution plan determination unit 140 or the water distribution plan determination unit 14 provided in the water distribution operation system 10. The water distribution plan determination unit 140 or the water distribution plan determination unit 14 included in the water distribution operation system 10 requests a new water distribution plan based on the acquired new operation set value.

When the water distribution plan determination unit 140 of the operation support device requests a new water distribution plan, the water distribution plan determination unit 140 may input the requested new water distribution plan into the water distribution operation system 10. The water distribution operation system 10 acquires a new water distribution plan and operates equipment in the water distribution network 50 such as a pump station based on the acquired water distribution plan.

When the water distribution plan determination unit 14 included in the water distribution operation system 10 requests a new water distribution plan, the water distribution operation system 10 controls the equipment of the water distribution network 50 based on the new water distribution plan.

In any case, when a plurality of operation setting value candidates to be updated are determined, the setting value update unit 260 updates the operation setting value by appropriately selecting one of the plurality of candidates. do. In this case, for example, among the histories stored in the operation history storage unit 261, candidates are selected based on the history in which appropriate measures have been taken. Alternatively, in the water distribution plan required by the water distribution plan determination unit 140, a candidate may be selected so that the number of facilities related to the updated operation setting value is reduced.

Subsequently, the operation of the operation support device 200 according to the second embodiment of the present invention will be described with reference to the flowchart shown in FIG.

First, the divergence degree evaluation unit 110 acquires information necessary for evaluating the divergence degree (step S201).

Next, the divergence degree evaluation unit 110 obtains the divergence degree by using the information acquired in step S201 (step S202).

Next, the priority determination unit 120 determines the priority based on the degree of deviation obtained in step S202 and the information regarding the configuration of the distribution network 50 and the like acquired in step S201 (step S203).

The operations of steps S201 to S203 correspond to the operations of steps S101 to S103 of the operation support device 100 in the first embodiment, respectively.

Next, the set value updating unit 260 performs a process necessary for updating the operation set value related to each of the facilities provided in the water distribution network 50 or the like by appropriately referring to the operation history storage unit 261 or the like (step). S204). The operation of the water distribution operation system 10 is changed according to the process of step S204.

As described above, in the operation support device 200 according to the second embodiment of the present invention, the set value updating unit 260 is provided for each of the facilities provided in the water distribution network 50 and the like based on the priority and the operation history of the water distribution network 50. Performs the processing required to update the operation setting values related to. That is, in the operation support device 200 according to the second embodiment of the present invention, the operation setting value to be corrected related to the equipment provided in the water distribution network 50 is added to the operation history in the water distribution network 50 in addition to the above-mentioned priority. Determined based on. Then, by using the operation history when appropriate measures are taken, it becomes easy to appropriately correct the operation setting value.

Therefore, the operation support device 200 in the present embodiment has the same effect as the operation support device 100 in the first embodiment. Further, the operation support device 200 in the present embodiment enables more efficient operation of the water distribution network as compared with the operation support device 100 in the first embodiment.
