摘要
随着光缆在电力系统中的大量应用,光纤保护通道的可靠性逐渐引起电力系统的重视。故障树分析法(FTA)可以通过构建故障树对系统的可靠性进行分析和预测。文章介绍了故障树的基本原理及可靠性的基本概念,建立了实际光纤保护通道的故障树。通过Relex公司生产的RelexStudio软件仿真,得到了光纤保护通道的有效性和通道中各个部件的重要度,并对不同保护通道的可靠性做了比较。
With the wide application of optical cable in electric power system, great attention has been paid on the reliability of optical fiber relay protection channel. FTA （fault tree analysis） method can be used to analyze and predict the reliability of a system through building a drafting fault tree. This paper introduces the basic principle of FTA and the concept of reliability. And the fault tree of optical fiber protection channel is formed. Through simulation with Relex Studio software produced by Relex Company, the effectiveness of optical fiber relay protection channel and essentiality of each component are obtained. The reliabilities of different relay protection channels are compared.
