故障信息处理系统中继电保护装置的可靠性研究

Reliability study of protective relays in relay protection and fault information system

针对继电保护装置的工作特点拟定了继电保护装置可靠性的特征量。建立了继电保护装置可靠性的马尔可夫模型,运用状态空间法进行可靠性分析。最后提出了如何利用故障信息处理系统中大量丰富的信息实现继电保护装置可靠性分析的方法。

This paper offers reliability indices of protective relays based on characteristic of protective relays. A Markov probability model is established. Using the state space method, the reliability of protective relays is evaluated. This paper also proposes a method of analyzing reliability of protective relays based on relay protection and fault information system.
