Inventor: ICHIKAWA MASAHIDE
IPC: G05B11/18
Filed: 1989-07-20
Abstract: PURPOSE:To perform proper conveying pump operation and obtain a proper a water reservoired amount by calculating the upper and lower limit water levels of a distributing reservoir of a specific time at optional time from demand prediction, planning the number of conveying pumps to be operated for water storage, and putting the conveying pump in operation according to the plan. CONSTITUTION:The quantity of water stored of the specific time at the optimum time is calculated from the demand prediction and the target water level of the distributing reservoir is calculated from the found amount. The target water levels are the lower limit water level at which water is stored for a certain time and the upper limit water level calculated from the stored quantity of a longer period. Then conveying pump operation is so planned that the water level of the distributing reservoir is in the range between the target water levels. Consequently, water can be stored in the distributing reservoir by the optimum amount corresponding to daily demand and even when the demand is small, water can be fed with a proper water level, so the power cost for the pumps is reduced.
