配电网GIS中的拓扑分析研究

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。本文就所开发的配电网G IS项目中,提出了基于图论的一种在G IS上构建配电网拓扑模型的算法并给出了其数据结构,将影响配电网拓扑结构的开关、T接点看作节点,将配电变压器和馈线段看作边,利用从属关系反映他们间的连接关系。这种算法节省了拓扑分析的计算时间,适合实时应用。最后,以电源点回溯的实现算法来说明拓扑分析方法的具体应用。经过实际应用表明,基于G IS的配电网拓扑分析方法具有很大的实用性和推广价值。

Study on the topology analysis in distribution network based on GIS

Topology analysis is one of the most essential parts of the advanced software of the distribution management system.Its research is of great value in theory and application.On the distribution network developed by the GIS project,the paper proposed a topology model algorithm and gave its data structure based on graph theory.The switching,T taps as nodes,distribution transformers and feeder lines as lines in distribution network topology,reflectd their connecting relations by affiliation.This method saved th...
