摘　　要：电力通信网是服务于电力系统的通信专网,它的可靠程度对电力系统安全、稳定运行非常重要。首先介绍了电力通信网的特点及复杂网络,其次重点从生存性和抗毁性两个方面来研究电力通信网的可靠性评估方法,采用平均距离法来衡量网络拥塞时的生存能力,抗毁性方面通过对拓扑图中节点和链路的重要度的计算来分析拓扑结构对网络可靠性的影响。最后通过南京市电力光纤传输网北环拓扑算例,分析验证改进的节点重要度评估法和链路重要度评估法的可行性。The degree of reliability of the electric power communication network,dedicated for the electric power system,is of great importance for safe and stable operation of the power system. First,this paper introduces the characteristics of the power communication network and its complex networking. Second,it discusses the methods for evaluating the reliability of the power communication network in terms of survivability and invulnerability. The survivability during network congestion is judged in the average distance method,while in the respect of invulnerability,the affection of the topological structure on the network reliability is analyzed through calculation of the degree of importance of nodes and that of links in topological graphs. Finally,taking the north loop of Nanjing Power Fiber Transmission Network as an example for topology calculation,this paper analyzes and verifies the feasibility of the improved methods for evaluating degree of importance of nodes and degree of importance of links.
