依据CIM的电网母线-支路模型,提出了一种基于母线群搜索的电磁环网拓扑辨识方法,并介绍了实现的具体步骤。研究了通过深度优先搜索实现同电压等级母线群搜索和母线间连通性的搜索,在此基础上提出了电磁环网存在性判定及环网的边路径搜索方法。最后结合电网实例分析验证了方法的正确性,可准确判断出电网中电磁环网的存在,并可搜索得到具体的环网路径设备。

An Electromagnetic Loop Network Topology Identification Method Based on Bus -batch Search

On the basis of a CIM-based grid bus/branch model,this paper presents an electromagnetic loop network topology identification method based on bus -batch search,and describes specific steps of this approach.It discusses how depth -first search is used to realize bus -batch search for the same level of voltage as well as search of connectivity between buses.Furthermore,the paper presents methods for judging existence of the electromagnetic loop network as well as its side path search.Finally,through analysis of actual grid cases,it is verified that the method is correct and that it can accurately judge the existence of the electromagnetic loop network in the grid,and search and locate the specific routing equipment of the looped network.
