摘　　要：电力通信网是一个典型的复杂网络,其关键节点对网络可靠性有较大影响。为准确评估节点重要性,文章从电力通信网的拓扑结构、承载的电力业务、节点类别和负荷以及根据运行统计数据得到的故障概率4个参数对节点重要性进行评估,并根据电力通信网拓扑结构的成环特性,提出了一种基于多指标最小环路的电力通信网重要节点判别方法。仿真结果表明,与其他方法相比,文章的算法能够更准确有效地评估节点重要性。The power communication network is a typical complex network,and its key nodes have a great influence on the reliability of the network.In order to evaluate the node importance accurately,this paper evaluates the node importance of the power communication network from four parameters:the topology,the power services carried by the network,the types and loads of the nodes,and the failure probability obtained from operating statistics.Based on the looping characteristics of the topology,an identification method of important nodes in power communication network based on multi-index minimum loop is proposed.The simulation results show that the proposed method can more accurately and effectively evaluate the node importance by comparing with other methods.
