The energy-saving program for a sewage pumping station in Shanghai was discussed in this paper.The overview of common sewage pumping station and the existing pump variable frequency control technology were briefly introduced.According to the existing operating conditions of the pump station,the necessity of variable frequency operation for feed pumping stations and drainage pumping stations was analyzed,and the fundamental principles of the energy-saving for variable frequency operation in drainage pumping stations were studied.The energy-saving control program of variable frequency pump was then proposed according to the original control basis.The pump was also optimally controlled using the minimum shaft power method,which favored improving the energy consumption level for the pump station.This study could make the pump meet the standards of safe operation,as well as the high efficiency and the energy-saving.
