摘 要:供水管网的分区管理是实现压力调控和主动漏损控制的重要技术手段,已在众多大城市得以实践。然而,传统分区方案大多依赖人工经验,缺乏科学依据。随着优化分区算法的发展,供水管网智能化分区具有显著优势,但这些算法通常用于未分区管网的初始划分,而如何对既有分区进行优化尚待研究。本文提出一种基于混合社区发现算法的既有管网分区优化重构方法,该方法创新性地融入虚拟管径以提高算法对既有边界的再利用率,并引入Jaccard指标量化既有分区与智能分区的相似度。结果表明:该方法能够综合考虑分区质量、边界再利用率和方案相似度;获得最优的重构方案,为既有管网的分区重构提供了技术支撑。Partition management of water distribution networks is critical for effective pressure regulation and active leakage control,widely implemented in many big cities.Traditional zoning approaches,however,largely rely on manual experience,often lacking scientific rigor.Recent advancements in optimized partition algorithms demonstrate significant potential for intelligent network partitioning,although their applications are generally based on unpartitioned networks.This study proposes an optimized reconstruction method for existing network partitions based on a hybrid community detection algorithm,which integrates virtual diameters to enhance the reutilization of existing boundaries.Besides,the Jaccard index is proposed to quantify the similarity between existing partitions and intelligent partitions.The results demonstrate the effectiveness of the method in obtaining an optimal reconstruction scheme that comprehensively considers partition quality,boundary reutilization,and scheme similarity,providing a more scientific guidance for the reconstruction of existing network partitions.
