摘　　要：供水企业向来是城市的用电大户 ,其用电量主要体现在泵站水泵机组的电耗上。供水泵站的高效运行对节约电能、安全供水具有极为重要的意义。文章对供水泵站的效率优化问题进行了探讨 ,在提出用指数曲线准确地拟合水泵性能曲线的基础上 ,建立了供水泵站效率优化问题的数学模型 ,并设计了相应的遗传算法进行求解 ,仿真实验结果表明了该算法合理、有效。Water supply enterprise consumes much of electric energy in the city, and the quantity it consumes mainly depends on the pumps of pumping stations. So it is important to optimize operation of water supply pumping stations, for safety water supply and saving energy. This paper presents an optimal scheduling model of water supply pumping stations based on approximation of exponent curve. Corresponding to the model, solutions based on genetic algorithm are introduced. The simulation resuls illustrate its validity. [
