基于故障树的电力通信网络拓扑可靠性分析

摘要

电力通信网络的拓扑对系统可靠性有较大的影响.文中同时考虑通信设备和通信链路的有效度,应用故障树的方法分析通信网络拓扑的可靠性,并且在分析过程考虑了通信链路失效事件的相关性.结果表明考虑通信链路的有效度后,相对于只考虑通信设备的有效度,不同网络拓扑的可靠性有了明显的区别.此外,文中基于考虑或者不考虑通信链路失效事件的相关性,对网络拓扑可靠性造成的影响进行了对比分析.%The topology of communication network has significant influence on system reliability.In this paper,based on fault tree methodology,the reliability of the communication network topology is analyzed by considering the validity of the communication equipment and the communication link.And the correlation of the communication link failure event is also considered in the analysis process.The results show that after considering the validity of the communication link,the reliability of network topologies are obviously different from that of considering only the validity of the communication equipment.In addition,it also compares the reliability of network topology on whether or not the correlation of communication link failure events is considered.
