Title: Control method for operation of water supply/exhaust pump
Inventor: MAEDA TETSUO
IPC: H02J3/14
Filed: 1982-11-22
Abstract: PURPOSE:To avoid operation of water supply/distribution pumps during a period around the peak of power consumption by putting water supply and exhaust pumps in operation compulsorily before the power reception attains its peak, and by keeping the supply and exhaust water tanks either full or empty under the peak. CONSTITUTION:A central control unit 1 shall give a compulsory operation command to a pump through pump control devices 4, 5 while power supply is not yet critical, in order to keep a supply water tank full and an exhaust water tank empty. Thus the water service is covered only by the supply water and exhaust water tanks during a period around the peak of power consumption so as to avoid overloading through operation of pumps. In the daytime when power supply is likely to be critical, power consumption is monitored on a power reception meter 10, and water service is commenced by operating the water supply and exhaust pumps compulsorily at the timing when the power supply has become roomy. Thus operation of pumps can be avoided under the peak of power consumption.
