摘要
介绍了电力系统继电保护中存在的隐形故障问题。通过介绍隐形故障的概念和特点,说明了隐形故障的危害性,在此基础上介绍了评价隐形故障危害性的方法,通过采取对隐形故障进行监测和控制的方法来减少隐形故障的发生,从而也就降低了系统发生大面积故障的可能性。最后还介绍了目前电力系统中对于隐形故障分析的应用情况。
This paper introduces the problem of hidden failures in relay protection of power systems. Based on the concept and characteristics of hidden failures, the method to evaluate the hazard of hidden failures is put forward. The supervision and control of hidden failures will lower the occurrence of hidden failures, consequently the chances of the wide-area system failures are reduced. At the same time, the status of application of hidden failure analysis in current power systems is described briefly.
