摘要
随着计算机技术、通信技术和电力系统一体化设备的发展,传统的变电站二次系统已经发展成为以设备智能化、信息传输网络化、信息模型及通信协议标准化为特点的一体化智能变电站二次系统。时间同步系统作为变电站非常关键的部分,对其开展可靠性的分析和研究显得尤为重要。本文阐述变电站时间同步系统运行过程中的各种事故,分析与总结影响系统可靠性的各种因素,在此基础上文章研究一种基于主成分分析(Principal Component Analysis,PCA)和故障树分析(Fault Tree Analysis,FTA)的时间同步系统可靠性分析方法。
With the development of computer technology,communication technology and integrated equipment of power system,traditional secondary system in substation has been developed into an integrated intelligent secondary system with the characteristics of intelligent equipment,network information transmission,information model and standardized communication protocol.Time synchronization system is a key part of the substation,so it is very important to carry out the reliable analysis and research.So this paper describes many kinds of operation accidents of time synchronization system,then analyses and summarizes the factors that affect the system reliability,finally this paper studies on an analytical method for reliability of time synchronization system based on Principal Component Analysis（PCA） and Fault Tree Analysis（FTA）.
