摘要

针对中国电网将出现1000 kV/500 kV电磁环网，甚至出现1000 kV/500 kV/220 kV多级电磁环网的情况，提出了一种基于网络社团结构特性量化分析的电磁环网分区方法。根据枢纽变电站分布情况及网络拓扑结构特性，应用GN分裂算法将电磁环网运行方式下低电压等级网络划分成若干分区;依据电力网络分裂过程中各个分区被划分出来的先后顺序形成电磁环网分区方案集合，并利用社团结构模块度指标衡量电磁环网分区质量。仿真结果表明，该方法能够有效反映电力网络社团结构特性，为形成电磁环网分区方案提供理论依据。

Abstract

The1000kV/500kV electromagnetic loop or1000kV/500kV/220kV electromagnetic loop may appear in Chinese power grid.A new method for electromagnetic loop partitioning based on quantitative analysis of network community structure characteristics is presented.According to the distribution of center substations and the topology structure of the network，several parts are separated from the low voltage level network in the operational mode of electromagnetic loop using GN dividing algorithm.The partition scheme set is formed in accordance with the sequence that every part separated from the network in the dividing process.And the modularity index of community structure is employed to evaluate the quality of the dividing results.Case studies demonstrate that the proposed method can effectively reflect the community structural characteristics and provides theoretical bases for electromagnetic loop partitioning.
