摘　　要：对电力通信网的脆弱性作出评估,找到网络中的薄弱环节,是保证电力通信网络系统正常可靠运行的重要基础工作。在前人的研究基础上,提出了基于链路已用率的电力通信网脆弱性的研究方法。首先对电力通信网的拓扑结构脆弱性进行了分析。然后将网络运行时的主要参数归结为数据在链路中的带宽,对基于链路已用率的网络运行脆弱性进行分析,找到网络的薄弱点。最后将结构脆弱性和运行脆弱性结合,求出电力通信网络整体的脆弱性。并且通过对一个14节点网络的分析,得到每个节点的脆弱性以及网络整体的脆弱性,从而对基于链路已用率的电力通信网脆弱性研究方法进行了验证。Assessing the network vulnerability and finding out the weak links of network are the important basic work to keep the normal and reliable operation of power telecommunication network. On the basis of predecessors＇ research, a method of power telecommunication network vulnerability based on link used rate is proposed. Firstly, the vulnerability of topology structure is analyzed. Then the main parameters of network operation are ascribed to the link bandwidth. And the analysis of network vulnerability based on link used rate is made to find out the network weak spot. Finally, the topology structural vulnerability is combined with the operational vulnerability to calculate the vulnerability of power telecommunication network as a whole. And through the analysis of a network with 14 nodes, it can get the nodes fragility and the whole vulnerability of network. Then the research method of power telecommunication network vulnerability based on link used rate is verified.
