Although the heat storage plant 19 is not shown in the figure, a heat source device such as a heat pump for generating heat, a heat storage tank for storing the heat generated by the heat source device, and heat generated by the heat source device or heat storage device. It is composed of a supply system for supplying heat stored in the tank to customers. The heat source device operation control device 17,
It is connected to the input device 1 and the output device 2, and is also connected to the heat source device control device 18 via a transmission device (not shown).

The heat source equipment operation control device 17 receives information from the input device 1 and an input portion 15 for taking in data with the heat source equipment control device 18 via a transmission device and an output portion 16 for sending out data. It has a man-machine input unit 3 for receiving and a man-machine output unit 4 for outputting information to an output device 2.

The process amount of the heat storage plant 19 obtained by the input unit 15 is partially calculated and statistically processed and stored in the process value storage unit 11 as process data, and the weather information is input from the input device 1 through the man-machine input unit 3. Is stored in the weather information storage unit 5, and the weather information and process data stored in these storage units 5 and 11 are stored in the load prediction unit 8
Be taken into. The load prediction unit 8 executes a calculation of heat demand prediction based on the weather information and the process data and the information obtained from the calendar 6, and the load predicted value obtained as a result is stored in the load predicted value storage unit 9. .

Further, the equipment information of the equipment specifications and configuration of the heat storage plant 19 is taken in from the input device 1 to the equipment information editing unit 7 through the man-machine input unit 3, and the equipment information edited here is stored in the equipment data. It is stored in the unit 10.

The process data stored in the process value storage unit 11, the predicted load value stored in the predicted load value storage unit 9 and the facility data stored in the facility data storage unit 10 are transferred to the operation plan creation unit 13, respectively. The operation plan created here and the current operation plan are stored in the operation plan data storage unit 14 as operation plan data.

The operation plan creating unit 13 prepares the operation plan according to a request from the monitoring unit 12 which monitors the operation when the heat source equipment is operated in the operation plan of the plant equipment from the process data taken from the process value storage unit 11. It can be modified.

The operation plan data stored in the operation plan data storage unit 14 is output from the output unit 16 to the heat source device control device 18 via the transmission device and the man-machine output unit 4 to the output device 2. Next, the operation of the heat source device operation control device configured in this manner will be described.

First, the heat source plant 1 is operated by the input unit 15.
The process measurement value 9 is input, and if necessary, calculation and statistical processing are performed and stored in the process value storage unit 11. In addition, the weather information storage unit 5 stores information about the weather up to N hours ahead, which is input from the input device 1 through the man-machine input unit 3.

When the data is stored in each storage unit in this way, the load predicting unit 8, the monitoring unit 12, the operation plan creating unit 13, and the facility information editing unit 7 perform the following processing based on each data. To be executed. (1) Processing in the load prediction unit 8

The load predicting unit 8 predicts the heat demand of the customer up to N hours (for example, 24 hours) ahead using the weather information, the information obtained from the calendar 6 and the process data, and the result is the predicted load value. Is stored in the predicted load value storage unit 9. In this case, the demand of heat consumers is often classified into several patterns depending on the day of the week, the weather, etc. Based on that pattern, the results of the day before, the day before the day, the minimum and maximum temperatures of the day, the weather, etc. To fine tune and predict the load value. (2) Processing in the monitoring unit 12

The monitoring unit 12 is activated at regular intervals, and whether stable supply and efficient operation of the heat source plant can be performed when the heat source equipment is operated with the state of the plant equipment and the current operation plan using the process data. If necessary, the operation plan creation unit 13 is requested to correct the current operation plan.

Here, the flow of processing of the monitoring unit 12 will be described with reference to the flow charts shown in FIGS. First, in FIG. 2, when the activation is started, in step ST1, the predicted heat load value, the residual heat storage amount, and the current operation plan are input, and based on these, the cold / hot water heat storage capacity, the heat source heat production capacity, the heat storage target, and the target. The allowable error is used as a parameter to determine whether there is a defect amount (heat excess or deficiency) in the predicted heat storage amount from the present to 22:00, and request it when the plan needs to be revised. In addition, when the error between the actual heat storage amount and the planned heat storage amount at every hour in the heat storage and heat radiation operation is an allowable error abnormality, a message of failure information (failure amount, predicted time of failure) is output.

After the plan correction request is issued in step ST1 or when it is determined that there is no defect amount, step ST1
In 2, the cold temperature switching state of the temperature storage tank in the heat storage tank is input to determine whether there is an abnormality in the temperature profile (inversion of the gradient). If there is no abnormality, the process directly proceeds to step ST3,
If there is an abnormality, a warning message is output and the process proceeds to step ST3.

In step ST3, the heat source inlet / outlet temperature, the heat source operating state, the heat storage amount, the operation plan and the predicted heat load value are input, and the heat source inlet temperature (or the heat source inlet temperature (or the heat alarm heat production capacity, trip warning temperature) is used as a parameter. (Exit temperature) has reached the trip warning temperature, and if it has not reached the trip warning temperature, a direct step ST4
If so, an alarm or message warning is output and the process proceeds to step ST4.

In step ST4, the heat source inlet / outlet temperature and the heat source operating state are input, and if the prescribed water supply temperature is not used as a parameter, the prescribed water supply temperature is not reached, or if it is predicted that the water supply prescribed temperature is not reached. It is determined that there is an abnormality in the side temperature, an alarm or a message alarm is output, and the process proceeds to step ST5.
Proceed to T5.

In step ST5, the heat source failure status, the heat source operating status, and the operation plan are input to determine whether or not a tripped or failed heat source is detected during the planned operation, and a tripped or failed heat source is detected. In this case, an alarm or message warning is output and the process proceeds to step ST6 shown in FIG.
Proceed to 6.

In step ST6, the water supply temperature and the return water temperature are input, and whether or not there is an abnormality in the water supply temperature and the heat storage tank outlet side temperature of each system using the water supply warning temperature, the return water warning temperature, and the specified water supply temperature as parameters. If there is no abnormality, the process directly proceeds to step ST7, and if there is an abnormality, a warning message warning is output and the process proceeds to step ST7.

In step ST7, the power consumption is input,
Power consumption (30
It judges whether or not the minute or integrated value for one hour exceeds 95% of the demand power. If it exceeds, it outputs an alarm or a message warning and goes to step ST8. If it does not, go directly to step ST8. .

In step ST8, the amount of change in the secondary water flow rate and the amount of change in the secondary water flow rate are input, and it is determined whether or not the amount of water flow near the load rise time suddenly changes by using the amount of change threshold value as a parameter, and the sudden change occurs. If so, an alarm or a message alarm is output, and if there is no sudden change, the processing of the monitoring unit 12 is terminated. (3) Processing in operation plan creation unit 13

The operation plan creation unit 13 is activated at a predetermined time or when a plan correction request is received from the monitoring unit 12, and uses the predicted load value, the process value, the facility data, and the current operation plan, Improve use of nighttime electricity Efficient operation of heat storage tank Reduce heat production cost

The operation plan is created and modified in accordance with the main points such as the above. The operation plan created here is the man-machine output unit 4
Is displayed on the output device 2 and transmitted from the output unit 16 to the heat source device control device 18. In this case, the equipment data used to create the operation plan is processed by the equipment of the heat storage plant and the plant configuration, which is processed without editing the equipment information 7, and the operation plan creation processing is separated from the equipment data. Therefore, even if the equipment data is changed, it is not necessary to change the operation plan creation process. Here, in the operation plan creating unit 13, first, the processing contents when creating a plan at a predetermined time will be described with reference to the flowchart shown in FIG.

In FIG. 4, when the operation plan creation unit 13 is activated, the load prediction value, the process value, the current operation plan, the equipment data, etc. are read from each storage unit in step ST9, and the process proceeds to step ST10.

In this step ST10, the predicted value of the heat source is taken in, and the heat storage transition is maximum at the daytime operation start time with the heat source-heat storage tank connection relationship, cold / hot water heat storage capacity, and heat source heat production capacity as parameters. Decide the heat storage target of cold and hot water and the heat storage of each time zone, the heat radiation initiative operation index so as to be the minimum at the end time, and output these as nighttime heat storage plan data. Then, in step ST11, the heat storage transition achieves the target. To determine the heat production target required to output, and output this as residual heat control plan data, and step ST12
Proceed to.

In step ST12, the heat production target necessary for achieving the heat storage target by taking in the heat source predicted value and using the heat source production capacity as a parameter is distributed to the open system heat source and the closed system heat source, and these are supplied to the heat supply plan data. Is output and the process proceeds to step ST13.

In step ST13, in order to efficiently perform the heat recovery operation by taking in the heat production target and the heat storage target and using the heat source heat production capacity and the cold / hot water heat storage capacity as parameters, the operation index of the cold / heat / heat recovery heat source. As a result, the cold / hot water initiative operation indexes are determined, and these are output as cold / hot water management plan data, and the process proceeds to step ST14.

In step ST14, the predicted heat load value is taken in, and the cold and hot water heat storage capacity, the heat source heat production capacity, and the scheduled adjustment time are used as parameters, and the heat production target amount in the scheduled adjustment contract time zone and the heat storage at the start and end times of the time zone are stored. Set goals,
These are output as scheduled adjustment contract operation guideline setting data, and the process proceeds to the next step ST15.

In step ST15, the heat load prediction value, the heat storage target, the heat storage, the heat radiation driven operation index, and the cold / hot water driven operation index are taken in, and the heat source heat production capacity, the cold / hot water heat storage capacity, and the contracted power are used as parameters to set the heat source operation pattern. The hourly heat source operation schedule is generated by heuristics. Then, these schedules are evaluated for leveling (peak cut, scheduled adjustment contract, etc.), continuous operation (reduction of start-up loss), and cold / hot water management (improvement of heat recovery efficiency), and the schedule that best fits the policy is selected. Output the heat source operation schedule (1 hour unit), and step ST
Proceed to 16.

In step ST16, the heat source operation schedule (in units of 1 hour), the heat storage target, and the predicted value of the heat load are fetched, and the heat source operation schedule is set in units of 1 hour using the heat source heat production capacity, the cold / hot water storage capacity, and the operation method as parameters. The expected heat storage amount at that time is calculated, and the deviation from the heat storage target created in the operation guideline is absorbed by correction in units of M minutes. At this time, the fine-tuned know-how is used to shorten, extend, and make the schedule continuous, and the finely adjusted heat source operation schedule (in units of M minutes) is output to end the operation preparation plan. Next, the processing contents when the plan correction request from the monitoring unit 12 is received will be described with reference to the flow charts shown in FIGS.

In FIG. 5, when it is activated by a plan correction request from the monitoring unit 12, the load prediction value, the process value, the current operation plan, the equipment data, etc. are read from each storage unit in step ST17, and the process proceeds to step ST18. .

In this step ST18, the heat storage amount and the residual heat amount are taken in, and the defective item of the present plant is checked from the monitoring results using the heat source-heat storage tank connection relationship, the heat storage amount upper and lower limit values, and the residual heat target value as parameters. If there is no defective item, the process proceeds to step ST20. If there is a defective item, the heat storage control amount and the residual heat amount deviation are output, and the process proceeds to step ST19.

In this step ST19, the failure / non-operation heat source number, the operation plan, and the predicted heat load value are fetched, and the operation of the heat source in which the failure or non-operation is detected in step ST18 is canceled by using the heat source heat production capacity as a parameter. The estimated heat storage amount is recalculated to output the corrected operation plan and the estimated heat storage amount. FIG. 6 is a flowchart showing this step ST19 in detail. In FIG. 6, in order to deal with a failure or non-operation of the heat source, it is first determined in step ST19-1 whether there is a failure heat source, and if there is no failure heat source, step ST19
-3, if there is a failure heat source, the failure heat source plan is canceled in step ST19-2 and the operation proceeds to step ST19-3. In this step ST19-3, it is determined whether or not there is a non-operating heat source, and if there is no non-operating heat source, the step ST19
19-5, if there is an inoperative heat source, step ST19
-4 to change the non-operating heat source plan, and step ST19
Go to -5. In this step ST19-5, the estimated heat storage amount is recalculated.

After the failure / non-operation countermeasure is taken in step ST19 as described above, or when it is determined in step ST18 that there is no defective item in the current plant from the current monitoring result, there is a heat storage defect in step ST20. If it is determined that there is a heat storage problem, the process proceeds to step ST21.

In this step ST21, the following processing is performed by taking in the operation plan, the heat storage expected amount, the heat storage target, the power demand, the heat load predicted value, the residual heat amount deviation, and using the heat source heat production capacity and the heat storage amount upper and lower limit values as parameters. I do. That is, when it is expected that the predicted heat storage amount at the time when the heat storage target is set deviates from the target by more than the allowable error, the correction is made by adjusting the start and stop times of the current operation plan. In addition, if the abnormal amount cannot be eliminated only by adjusting the start and stop times of the current plan, the start of the current plan will be canceled and the plan will be set according to the operation plan creation process of "when started at a predetermined time". To output the corrected operation plan data and the estimated heat storage amount. 7 and 8 are flowcharts showing this step ST21 in detail.
In FIG. 7, the step ST is the first step for dealing with the abnormal heat storage amount.
21-1 checks the heat storage amount, and step ST21
-2, it is determined whether or not there is a problem with the heat storage, and if there is no problem, prepare for the next abnormality in the amount of heat storage, and if it is determined that there is a problem, the process proceeds to step ST21-3, where the heat storage problem is resolved. Is performed, and the process proceeds to step ST21-4. In step ST21-4, it is determined whether or not the problem has been resolved. If not, step ST21-4
Return to 21-1, and if it has been resolved, step ST21-
Request re-planning according to No. 5, and prepare for the next abnormality in the heat storage amount.

In step ST21-3, the heat storage defect solving process as shown in FIG. 8 is performed. Step ST2
The heat storage defect resolution process in 1-3 is performed in step ST21-
In 3a, the correction target is determined and the correction target time zone is determined. In step ST21-3b, the modifiable plan is selected, and the process proceeds to step ST21-3c. This step ST21-3
In c, it is determined whether there is a correctable plan, and if there is no correctable plan, it is determined that the solution has failed and the next heat storage failure is resolved. If it is determined that there is a modifiable plan, a correction candidate is created in step ST21-3d, and it is determined in step ST21-3e whether there is a correction candidate. When it is determined in step ST21-3e that there is no correction candidate, it is determined that there is a correction candidate in preparation for the next heat storage defect resolution as a solution failure and step ST2.
The adoption plan is determined in 1-3f, and then step ST21.
Update the unit plan with -3g to prepare for the next heat storage failure.

When the abnormality of the heat storage amount is dealt with in this way, returning to FIG. 5 again, it is judged in step ST22 whether there is a re-planning request, and if there is a re-planning request, a re-planning request is made and output in step ST25. Create a file. If there is no re-planning request, it is determined in step ST23 whether or not there is a plan modification. If there is no modification, an output file is created in step ST25. I do.

That is, in step ST24, if the time at which the operation plan and the correction plan must actually be applied from the current time is within L time from the current time, the correction plan such as the corrected operation plan and the estimated heat storage amount is output. Otherwise, it outputs a message telling you to look at the situation for a while. FIG. 9 is a flowchart showing this step ST24 in detail. FIG.
In step ST24-1, the correction execution time is calculated, and in step ST24-2, it is determined whether the correction execution time ≦ current time + margin time is satisfied, and if it is satisfied, the correction is executed and the correction time must be satisfied. For example, the revision will be postponed in preparation for the next revision decision. (4) Processing in the equipment information editing unit 7

Information relating to equipment specifications and equipment configuration of the heat storage plant is edited by the equipment information editing unit 7 via the input unit and stored in the equipment data storage unit 10 as equipment data.

As the recent equipment data, information about the equipment whose specifications and configuration may be changed when the heat storage plant is operated is developed and stored in a form that the operation plan creation unit 13 can easily use. To do. The following describes how to develop the heat storage tank and heat source equipment as an example.

The heat demand of the customer greatly depends on the season,
A lot of cold water is needed in summer, and a lot of hot water is used in winter. In order to respond to such changes in demand, many heat storage plants are equipped with multiple heat storage tanks, and the number of heat storage tanks for cold water heat storage and hot water heat storage tanks is adjusted according to the demand. There is. If the operation plan creation unit 13 manages each of these heat storage tanks directly, it becomes necessary to change the operation plan creation process when the number of allocated heat storage tanks changes at the turn of the season.

In order to avoid this, the equipment information editing unit 7 generates a logical heat storage tank for each heat type from a physical heat storage tank that depends on the heat storage plant. That is, the specifications of all heat storage tanks used for cold water heat storage are integrated to generate logical cold water tank data as if one cold water tank exists. By similarly creating the logical hot water tank data, the operation plan creating unit 13 can always consider one cold water tank and one hot water tank to create an operation plan.

One heat source device can be used for cold water production or hot water production depending on the season. Further, the heat recovery type heat pump can produce cold water and hot water at the same time, but if the heat recovery operation is not performed, only cold water is produced. As described above, the heat source device has different types of heat that can be produced at one time depending on how it is operated.

Normally, the types of heat that can be produced are called "modes", which are a cold water mode, a hot water mode, and a heat recovery mode. The facility information editing unit 7 checks the modes that one heat source device can have from the specifications of one heat source device, creates logical heat source device data for each mode, and which mode is available in the current plant state. Information is added and stored in the facility information data storage unit. The operation plan creation unit 13
Since the operation plan is created using the logical heat source device that can be created at present, when the mode is changed, the equipment information editing unit 7
By simply changing the type of mode currently available,
It is possible to create an operation plan of the heat source device in the new mode without changing the operation plan creation process.

As described above, even if the usage pattern or configuration of the equipment changes, the operation plan creation process can be made without any change and the operation plan can be created in accordance with the new plant configuration, and the heat storage plant supplies heat. When the heat consumption pattern of existing consumers has changed significantly and cannot be covered without adding new heat source equipment, the specifications of the new heat source (apparatus type, heat production capacity, power consumption, etc.) are added. By inputting the configuration of the subsequent plant (connection relationship between heat source and heat storage tank, etc.), it is possible to create the operation plan of the heat source equipment in the new plant configuration without changing the process for creating the operation plan. .

When a new heat storage plant is installed,
It is not necessary to recreate the operation plan creation unit 13 from the beginning, and the operation plan can be created by only inputting the specifications of the new facility and the plant configuration.

The above is a description of the operation of each main part of the operation control device of the heat source device. In particular, in the present invention, the predicted heat load value, the current heat storage amount, the heat storage tank capacity, and the heat production capacity of the heat source device are used. When the information about the change of the equipment configuration is received separately from the operation plan creation unit 13 of the heat source device after the current time, the information is changed to the equipment configuration data and stored in the equipment data storage unit 10. This is because the changed equipment configuration data stored in (3) is given to the operation plan creation unit 13. Therefore, even if the specifications of the equipment of the heat storage plant are changed or the configuration of the heat storage plant is changed, these pieces of information are managed separately from the operation plan creation unit 13, so that the operation plan creation is performed. It is possible to create an operation plan of the heat source device and monitor the plant in the changed plant configuration without any modification to the processing of the unit 13. The present invention can be applied not only to the heat source device but also to the control of the valve of the supply system, the water pump, and the like.

[0054]

As described above, according to the present invention, the information about the equipment of the heat storage plant is managed separately from the operation plan creation unit, so that the specifications of the equipment may be changed, Even if there is a change in the configuration of the heat storage plant, a heat source that can create an operation plan for the heat source equipment in the changed plant configuration and monitor the plant without any modification to the processing of the operation plan creation unit An operation control device for equipment can be provided.
