针对现有研究忽视或较少考虑泵站优化配置问题的现状，在分析城市变频调速给水泵站工况的基础上，提出了可行泵的概念，并应用工况点流量分析法来确定泵站配置过程中可行泵的范围．从实际情况出发，得出泵站配置的约束条件，进而建立了以泵站年运行能耗最小为目标函数的优化配置模型。同时给出了该优化配置模型的求解方法．仿真实验表明，提出的给水泵站的优化配置模型简便有效，精确度高，因而对指导城市给水泵站的建设工作有积极的意义．

英文摘要：

For the neglected and seldom considered optimal configuration in recent research, the concept of a feasible pump is proposed based on the analysis of the urban water-supply operation with variable frequency speed control. Then the method of operation-point flow rate is used to determine the range of feasible pumps. According to the engineering requirement, the optimal configuration model and its solution is given with the least total energy consumption of the pump station as the target function. The simulation results show that the optimizing configuration model is convenient and effective with high precision, which contributes much to the configuration of urban water-supply pump stations.
