| Abstract: | 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. |
