Optimal Valve Control in Water Distribution Systems Based on Cuckoo Search

针对城市给水管网漏损日益严重的问题,采用压力管理的策略,通过在管网中安装调压阀降低管网压力,从而达到减少管网真实漏损的目的.利用一个新的优化算法布谷鸟算法,建立管网调压阀优化模型,确定调压阀的数量、最优安装位置以及最优操作方式,并在算例管网中与遗传算法进行对比测试.结果显示:布谷鸟算法由于其调节参数少,随机搜索路径优,在调压阀优化设计中显示了更优秀的优化能力,显示了强大的算法应用可扩展性,使得对真实管网通过最优化算法来确定最佳阀门控制策略成为可能.

In order to solve the growing leakage problem of the city water distribution systems, control valves were proposed to be installed in the pipeline to decrease the pipe pressure. An optimized model was established by means of Cuckoo Search to determine the effective numbers of valves and their location. A comparative study was made to show the difference between Genetic Algorithm and Cuckoo Search. The results show Cuckoo Search has a better performance in terms of searching speed and parameter requirement, which reveals the potential of the proposed optimization model for control valves in a real-life water distribution system.
