Abstract

본 발명은 전력 계통 보호계전기의 모니터링장치에 관한 것으로서, 종래의 경우 스테이션 유니트(SU)에서 데이타를 분석하기 고장을 해석하기 때문에 통신이 두절되었을 경우에 고장해석과 같은 데이타 분석을 할 수 없으며, 현장에서 보호제어유니트(PCU)의 간단한 고장분석을 할 수 없다는 문제점을 감안하여 본 발명은 발, 변전소등 전력계통현장에서 사용되는 디지탈 보호계전기의 운전상태, 계전기 상태, 기기 상태, 사고시의 고장 데이타, 정정치의 정정등을 보호계전기의 모니터링 소프트웨어가 실린 PC를 이용하여 모니터링 및 정정할 수 있도록 한 것이다.The present invention relates to a monitoring device for a power system protection relay, and in the conventional case, because the station unit (SU) analyzes data and analyzes a failure, it is impossible to analyze data such as a failure analysis when communication is lost. In view of the problem that a simple failure analysis of a protection control unit (PCU) cannot be performed in the present invention, the present invention provides an operation state, a relay state, a device state, a fault data in case of an accident, and a digital protection relay used in a power system site such as a foot and a substation. Correction of the correction values can be monitored and corrected using a PC equipped with the monitoring software of the protection relay.
