ABSTRACT

The partition of complex Water Distribution Systems (WDSs) is required in order to simplify and facilitate the routine cumbersome management tasks. As a representative community detection algorithm, the Fast-Newman Algorithm (FNA) can efficiently partition the network into District Metered areas (DMAs) based on the modularity index. However, only the topological attribute is considered in the classic version. In this work, the modularity index and corresponding mergence mechanism of FNA are modified first to improve water demand similarity among DMAs; then, an optimal selection of cut positions where flow meters or gate valves will be installed is conducted to further improve water demand similarity among DMAs; finally, the inflow pipes of DMAs are optimally selected considering economy and the impact on hydraulic performance of WDSs. The proposed approach is applied to three cases and the results reveal the superiority of this method.

摘要

为了简化和简化日常繁琐的管理任务，需要对复杂的水分配系统（WDS）进行分区。作为一种代表性的社区检测算法，快速纽曼算法（FNA）可以基于模块化指数将网络有效地划分为区域计量区域（DMA）。但是，经典版本仅考虑拓扑属性。在这项工作中，首先修改FNA的模块化指标和相应的合并机制，以提高DMA之间的需水相似性；然后，对将要安装流量计或闸阀的切割位置进行最佳选择，以进一步提高DMA之间的需水相似度；最后，考虑到经济性和对WDS水力性能的影响，对DMA的进水管进行最佳选择。
