摘　　要：当前对电力通信网的可靠性研究主要集中在网络的可靠性分析评估上,缺少可靠性保障方面的研究成果,如何有效全面地保障电力通信网的可靠性仍是亟待解决的研究问题。文章针对网络拓扑结构和节点承载业务提出面向电力通信网的节点重要度评价方法,充分考虑节点在网络结构中的作用和网络中当前状态下节点承载的电力业务风险状态来综合评估计算节点的重要度;基于该节点重要度评价方法,提出了电力通信网的可靠性保障方法,面对电力通信网络中不同层级的优化采用不同的节点重要度考核指标。通过对该方法进行仿真验证,结果表明基于节点重要度的电力通信网可靠性保障方法可靠有效。At present,the research on the reliability of power communication network is mainly focused on the reliability analysis and evaluation of the network,with few research results on reliability guarantee.How to guarantee the reliability of power communication network is still an urgent problem.This paper presents an evaluation method of node importance for power communication network based on network topology and node carrying service.The method fully considers the role of the node in the network structure and the risk status of the power service carried by the node in the current state of the network to comprehensively evaluate the importance of nodes.Based on this evaluation method,a reliability guarantee method for power communication network is proposed.Different importance standards of nodes are adopted for the optimization of different levels of power communication network.The simulation results show that the reliability guarantee method based on node importance is reliable and effective.
