为了提高城市供水管网漏失点定位检修效率,该文提出了一种基于供水管网压力监测点的漏失区域定位方法。该方法根据模糊聚类理论对管网节点进行漏失敏感分析,得出测压点的优化布置方案,在此基础上建立漏失区域定位模型,并通过遗传算法求解模型,确定漏失发生的位置。工程实例表明该方法简便易用,定位较为准确,能有效应用于供水管网的漏失区域定位中,缩小漏失检测范围,提高工作效率。

In order to improve leakage point location in water distribution systems efficiently,a method for locating leakage point based on pressure monitoring points was proposed. The method applied the theory of Fuzzy Clustering to carry out leakage sensitivity analysis for nodes in water distribution systems and obtained optimized schemes of pressure monitoring points. Then,a leakage location model was established and calculated by Genetic Algorithms,which could find out the leakage location. A practical example indicates that the proposed method is easy to use and has comparatively high accuracy,which can be applied in locating leakage effectively with greatly reducing the scope of leakage detection and improving working efficiency.
