This paper presents a method of energy saving control of centrifugal pump running in a multi-pump parallel inverter under the same pipe network. It is a suitable method to simulate the number of stations in a series of working conditions which consumes the lowest energy. Taking the simulation calculation and pipe network analysis of the pump system as a means, the comprehensive evaluation of various water pump system scenarios is carried out. At the same time, this paper analyzes the control method and its calculation process. Combined with the case, the pump energy consumption under this control method in variable units was introduced.
