Abstract

본 발명은 전차선로의 고장점 표정방법 및 그 시스템에 관한 것으로서, 전차선로의 고장 발생시 고장지점의 검출 및 계전기의 고장시에도 고장지점을 정확히 검출할 수 있는 고장점 표정방법 및 그 시스템에 관한 것이다. 본 발명의 전차선로의 고장점 표정방법으로서, 전차선로상 제1 지점에서 제2 지점까지 거리에 따른 순방향 임피던스 및 역방향 임피던스를 측정하여 거리의 임피던스 함수로 저장하는 단계와, 고장 발생시 측정된 제1 지점에서의 순방향 임피던스 및 제2 지점에서의 역방향 임피던스를 이용하여 제1 지점으로부터 순방향 임피던스 함수에 의하여 대응되는 제1 거리 및 제2 지점으로부터 역방향 임피던스 함수에 의하여 대응되는 제2 거리를 연산하여, 상호 매칭되는 위치를 고장지점으로 판단하는 단계를 포함하는 것을 특징으로 한다.
