【摘要】 配电网络拓扑分析是配电管理系统高级应用软件的重要组成部分，其研究具有重要的理论和应用价值。它也是配网管理系统其它高级应用软件的基础，作为一个公用的基础模块，其性能直接影响配网管理系统中其他应用软件的运行。 本文详细地阐述了网络拓扑分析中两种常用的分析方法：邻接矩阵法和树搜索法。针对配电网络的特点，对两种方法分别提出了改进的算法。对邻接矩阵法，提出了节点消去法的拓扑分析方法；对树搜索法，将开关变位对网络拓扑结构的影响转化为支路的投切和母线的合并或分裂对网络拓扑结构的影响。实例表明，改进算法节省了配网拓扑分析的时间，适合于配网拓扑的实时分析。更多还原

【Abstract】 Topology analysis is one of the most essential parts of the advanced software of the Distribution Management System. The research on it is of great value in theory and application. It also is the base of other advanced software of the Distribution Management System. As a public module, its performance directly affects the use of other advanced software of the Distribution Management System.This paper sets forth the two methods for topology analysis: neighboring matrix method and tree_search method, which are in common use. According to the characteristic of the distribution network, this paper improves the two methods. To the neighboring matrix method, the paper puts forward a method, which decreases the number of the nodes step by step. To the tree_search method, the paper transforms the effect on the network topology of the switch’s state change into the effect on the network topology of the edge’s state change and bus’s combing or breaking up . The improved method saves the time of the distribution network topology analysis, and is suitable for the real_time applications.更多还原
