Method and apparatus for judging substation failure

摘要

The present invention relates to a method and an apparatus for judging substation faults, and an object thereof is to quickly find a part corresponding to a fault facility. If it is determined that there is operation information of the protection relay among the data obtained from the alarm database, it is determined whether the protection facility of the operated protection relay is the transmission line if there is operation information. If the protection information is the line protection relay, If it is determined that there is a failure in the transmission line, it is determined that the protection relay is operated due to the failure of the substation connected to the nearby protection relay, and the substation to be determined as the faulty substation is determined. If it is not a relay, the substation where the operation relay is installed is determined as the substation to be fault-detected. If there is no protection relay operation, the breaker operation is judged to be caused by human operation, not by fault occurrence.
