。More specifically, in elements 1o and 11, necessary data is initialized 1. as described above. The predicted demand for water supply during H period and the maximum/minimum Honda discharge by one company are -Fjλ, and based on these data, Δ is always calculated as described above at 1fiJ i6. Here, it is assumed that 1 m of pump installation consists of a constant number of rotational speed pumps with a valley ψ and a large discharge amount, and two types of pumps are considered as the operating method. As shown in Fig. 4, the pump discharge amount is always set between the maximum pop discharge amount 21 and the minimum pop discharge amount 22, but first of all, as the first operating method, the pump discharge amount is set to be between the maximum pop discharge amount 21 and the minimum pop discharge amount 22. From the current point t, the pop discharge amount ahead of ΔtII 1i41 is the maximum.
Minimum discharge - If the curve is the same, the number of pumps in continuous operation should not be changed (No. 4, No. 23), and the operation method II is to increase the maximum and minimum discharge from the lowest point of operation cost. This is a method (41st numeral 24) of switching the number of bongs to be as close to the minimum discharge amount as possible between the volume curves.

Find out the best way to drive in this situation! The operation adopted there will be adopted at the current time.・In general, there are six operating methods (switching time, variable discharge rate, number of starting/stopping pumps, volume of peaches, etc.), and the most suitable (minimum operating cost) is selected from all of them. It is not possible to choose the driving method. For this reason, we have selected several cases in advance and selected the most suitable case from among the seven. First, by determining the maximum and minimum pump discharge amounts, it is possible to ensure a stable pop-up operation range, a limited range of water level fluctuations in the water distribution tank, and a stable flow of water. In addition, the operating method is limited to 1 and 1, and the case with the least number of pump pumps and the lowest operating cost is selected. By changing the pump promotion interval consideration from 1 to K, the optimum switching time can be selected. Regarding the pump buildings and number of pumps when switching over, we have selected a combination that requires fewer switches and is more efficient in operation than all combinations of existing equipment. Based on the above, from among the operating methods for the 2/K case, the operating method that minimizes the pump operating cost and has the least amount of praise in history has been determined. The driving method performed in the first time step of the driving method is implemented at the present moment (1) //I! 1, it is possible to continuously switch the number of units at the current time for optimal operation at 1 yaw Ibj.

間隔1fJに行なうことを特色とするポンプ運転方法。Consulting l-111, lJ + Hiyaku Anhod Water-, set the Mondai and Minimum end ng discharge - Song IH, and set the maximum and minimum effusion from the current time to the previous maximum and minimum effusion + 1th1 gland. The continuous operation cost and the number of switching times are evaluated for each time step for each of the minimum number of pump switching methods and the minimum continuous rotation method that brings the number of pumps close to the minimum discharge curve. Considering the number and capacity of the pumps, from all combinations of the number of units that can be started or stopped when switching pumps, select the number that will minimize the number of units to be switched and maximize operating efficiency, and Yuzu 1.
Using the daily forecast from the current time as a pattern, we calculate the case with the minimum cost from the above-mentioned minimum operating cost continuous method, and the case where the minimum number of pumps is switched from the minimum number of pumps switching method using the daily lr + J plan. A pump operating method characterized in that the bong cutting at the current time is performed at a predetermined rectangular time interval of 1 fJ.
