Optimal Pump and Inverter Control for Drinking Waterand Wastewater Treatment Systems

摘要

The method for minimizing energy of the inverter driven pumps to realize energy savingsand cost reductions is highly significant for the drinking water and wastewater treatment systems.This paper presents a systematic optimization method based on topological and geometric propertiesof the objective function for obtaining multiple local optimal solutions of the inverter driven pumpsystems. For the purpose of illustrating the proposed method, the inverter driven two-pump system isstudied numerically. The three local optimal solutions are obtained, and one of the obtained solutionsleads the lowest active electric power consumption. The numerical result shows the effectiveness ofthe proposed method.
