摘　　要：以复杂网络理论为基础,对电力通信网进行拓扑建模、基本参数计算和网络特性分析,对于确保电力系统安全运行和加强电网健壮性有重要影响。针对电力通信网的业务特点,依据度数、介数指标找出网络脆弱点,修改传统效能函数,并以此函数作为衡量网络脆弱性的指标,确定网络脆弱点。最后,以某2个实际电力通信网为例进行了网络特性分析,针对不同故障模式对其进行攻击脆弱性仿真。根据仿真结果,分析了异构网络的本质脆弱性,总结了影响电力通信网脆弱性的因素。Based on complex network theory,this paper analyses the topology modeling,basic parameters and network performance of power communication network.In view of the service characteristics,it finds out the vulnerabilities of the power communication network and revises the traditional efficiency function regarded as the index to measure the vulnerability of the network.In the paper,the network performances of two cases are analysed and simulation of vulnerability attack at different failure modes are carry on.Finally, on the basis of simulation results, the factors which have influence on the vulnerability of power communication network is summarized.
