雨水泵站水泵机组启停优化

为解决雨水泵站运行过程中存在的水泵频繁启停问题, 提出一种水泵机组启停优化方法.该方法通过分析泵站的设计参数和水泵机组运行原理, 建立启泵水位优化模型, 并运用暴雨洪水管理模型(storm water management model, SWMM)和粒子群优化算法(particle swarm optimization algorithm, PSO)对模型求解, 最终得到水泵机组的最优启泵水位.通过实例将优化方法与传统的人工调试方法进行对比, 验证了其可行性.研究结果表明：采用优化方法得到的启泵水位可使机组启停次数达到最小, 实现了较好的水泵启停效果.同时优化方法也避免了复杂的人工调试过程, 得出的优化结果为雨水泵站启泵水位的选取提供参考
A pump start-stops optimization method was proposed to realize the frequent start-stops in rainwater pump station. Through analyzing the design parameters and operation principles, the optimization model of pump start water level was obtained by SWMM(storm water management model) and PSO(particle swarm optimization algorithm). The feasibility of the optimization method was verified by comparing with manual debugging method. The research results show that the optimization method can minimize the start-stop frequency, achieve a better effect of bump start-stops and get rid of the complex manual debugging process, which will provide reference for the pumping water level selection of rainwater pumping stations
