Research on Energy-Saving Operation of Variable Frequency Speed Regulation System for Water Supply Pump Station

In order to explore the optimized energy-saving operation mode of variable frequency speed regulation system for water supply pump station, taking unilateral water consumption as the assessment target, the operation principle of water supply system was analyzed. Based on the measured data of the water supply pump station system, the Matlab was used to fit the mathematical equations and curves. Taking the Botou water supply pump station in Cangzhou as an example, the energy loss and distribution of the water supply system were analyzed. The efficiency model was put forward under the same operating conditions. The unilateral water consumption of different schemes was calculated and compared, and the optimal operation scheme was determined. The results show that the optimal operation scheme under the same working conditions can improve the efficiency of water supply and reduce energy consumption.
