Abstract


Wide area adaptive backup protection needs to locate fault element and fault section before backup protection action, and prepare for modifying fixed value of backup protection. The fault localization that works for wide area adaptive backup protection is the precondition of adaptive backup protection. Recently, numerous experts and scholars have done extensive studies on power grid alarm processing and fault diagnosis, however all of these methods utilized action information from protection or circuit breaker that is fulfilled after protection action. In this paper, according to different kinds of failures, we will study an effective fault identification technique for electrical engineering. Ill. 1, bibl. 14, tabl. 1 (in English; abstracts in English and Lithuanian).
