摘要
利用两两节点的相对压力差值,建立管网水压的相似系数矩阵,并通过聚类分析,实现了节点的分组与测压点选择.该方法能够准确反映节点水压的区域分布特性,为管网的监控调度奠定基础.同时,以Delphi7为平台,编制了动态的测压点布置应用程序,即根据用户需要实现管网测压点的合理配置,以满足不同的管网监测需求.实例计算表明,基于压差相似系数法的测压点布置较为合理,具有一定的代表性.所开发的测压点优化布置程序,运行稳定、结果准确,是实现准确的管网状态模拟、优化调度和事故预警的有效辅助工具.
The pressure similarity method is proposed for optimal layout of pressure measurement points in water supply networks. The relative difference between any two nodal heads is used to establish the matrix of pressure similarity coefficient. Thus, nodes are grouped by clustering analysis and pressure measurement points can be selected out. This kind of distribution can correctly reflect the regional characteristics of network pressure and become the basis of network control and scheduling. Moreover, a software system is developed with Delphi 7 to provide automatic distribution according to users＇ needs and monitoring requirements. The application on a practical network showed that the pressure similarity method generated reasonable and representative results. The developed software was stable during the running and was useful for network simulation, optimal scheduling and warning of accident in advence.
