十分ではなく、エネルギロスが大きい問題点があった。However, the actual heat load often deviates from the heat load prediction due to the abnormal heat load due to the weather. However, in the conventional heat source control device, such a prediction error occurs. However, there was a problem that it was not equipped with a flexible correction function, and it was not possible to control as desired in response to the actual heat load. In addition, there is a heat source control device that performs heat source control while correcting the load prediction and the heat source operation plan in order to cope with the misprediction.However, in such a conventional heat source control device, it is possible to correct the misprediction. Since the required calculation load becomes large, correction processing of a long time span, for example, every hour, is performed, and there is a problem that fine control is not sufficient and energy loss is large.

In the time zone of 00:00 to 15:00, the heat storage amount of almost 100% is maintained, and the heat storage amount is gradually reduced as the heat consumption is gradually reduced.
At 22:00, which is the end time, a transition plan is set so that it becomes almost 0.

In every same cycle in accordance with an operation command based on the heat production plan from the operation planning unit 9. However, there are many cases where the heat consumption by the heat load 2, 2, ... Group deviates from the prediction depending on the weather of the day and other factors. In that case, according to the flowchart shown in FIG. The necessary operation plan is revised every fixed period.

As shown by the broken line i, if the actual heat load is separated to the side larger than the predicted heat load, the transition of the integrated heat storage amount calculated by the heat storage amount calculation unit 10 is shown by the broken line ii in FIG.

Therefore, the control execution unit 11 corrects the time when the number of operating the refrigerators 3, 3, ... Group of the heat source is increased to the time t2 ′ indicated by the broken line which is earlier than the originally scheduled time t2, and thereby the heat storage amount. The operation plan is modified to make up for the shortfall from the plan. If a shortage of heat storage amount is detected at the time when the number of operating units of the refrigerators 3, 3, ... Group is approaching, the number of operating units before the number of operating units is reduced by the time to compensate for the shortage. Corrective operation will be performed to extend the time.

テップS1)。The current actual heat storage amount is calculated from the heat storage amount calculation unit 10, compared with the planned heat storage amount of the heat storage amount transition planning unit 8, and necessary corrections are added to the operation plan from the operation planning unit 9 according to the magnitude. While controlling the number of refrigerators 3, 3, ... (Step S1).

6)。However, in the comparison of step S1, if the current heat storage amount is smaller than the planned heat storage amount by exceeding the allowable range b / 2, the actual heat load is larger than predicted and the heat storage amount is insufficient. Since it has occurred, it is necessary to increase the amount of heat production, and the operating number of the refrigerators 3, 3, ... Group is increased from the initially planned number. Therefore, if the stop time of one refrigerator 3 is scheduled to arrive before the next control cycle, the stop time is extended to the next cycle for operation (steps S3, S4). On the contrary, if the stop time of one refrigerator 3 does not arrive before the next control cycle, one new refrigerator 3 is newly activated to increase the heat production (step S5). , S

Since it has occurred, it is necessary to reduce the amount of heat production in order to save energy, and the operating number of the refrigerators 3, 3, ... Group is reduced from the initially planned number. Therefore, if the start time of one refrigerator 3 is scheduled to arrive before the next control cycle, the start time is deferred until the next cycle (steps S7 and S8), and vice versa. If the activation time of one refrigerator 3 does not arrive within the control cycle of step 1, the one refrigerator 3 is immediately stopped to perform control to reduce the heat production amount (step S).

However, in the case of heat storage amount control of warm heat, contrary to the above embodiment,
If the current heat storage amount is smaller than the heat storage planned amount, the operation control of the heat source of the boiler or heater is performed so as to increase the heat production amount, and if the current heat storage amount is larger than the heat storage planned amount, the heat production amount is suppressed.

The heat storage amount change planning unit plans the time change of the heat storage amount required for the heat storage amount, and the heat storage amount that matches the heat storage amount transition plan in the heat storage tank based on the correspondence relationship between the change in the predicted heat load amount and the change in the heat storage amount. A heat production plan for storing heat is established by the heat production planning unit, and the actual heat storage amount detected by the heat storage amount detection unit and the heat storage amount planned value planned by the heat storage amount transition planning unit are constantly maintained by the heat production plan correction unit. The heat source operation control unit is compared with the heat production planning unit established by the heat production planning unit according to the deviation, and based on the heat production plan established by the heat production planning unit and the correction command of the heat production plan correcting unit. Control the operation of the heat source. The fluctuation of the heat storage amount of the heat source can be monitored, and if a deviation occurs, the heat production plan can be corrected immediately and the heat source operation can be carried out. You can control.
