According to the present invention, a system and a method for detecting and isolating a faulty load in an auxiliary power supply for an electric railway vehicle comprises: a plurality of load groups for receiving power from an auxiliary power supply; the auxiliary power supply for supplying power, required to drive loads belonging to the plurality of load groups; and an integrated train control device for detecting and isolating a load causing a ground fault among loads that can be cut off if ground fault information is received from the auxiliary power supply. Therefore, the system can detect and isolate a grounding (line-to-line short circuit) occurrence area by simply changing only a software logic without any additional wiring work or installation of additional devices, and then enables normal operation, thereby improving train operation safety and preventing vehicle operation failures with a simple logic change.

    본 발명에 따른 전기철도차량 보조전원장치 고장부하 탐색 및 격리 시스템은 보조전원장치로부터 전원을 공급받는 복수의 부하군; 복수의 상기 부하군에 속하는 부하들이 구동하는데 필요한 전원을 공급하는 보조전원장치; 및 상기 보조전원장치에서 접지고장 정보가 올라오면 차단이 가능한 부하들 중, 해당 접지고장을 발생시키는 부하를 탐색하여 격리시키는 열차종합 제어장치;를 포함하는 것을 특징으로 하는 전기철도차량 보조전원장치 고장부하 탐색 및 격리 시스템.;를 포함하여 별도의 배선작업이나 추가적인 장치 설치 없이 소프트웨어 로직 변경만으로 접지(선간단락) 발생부위를 찾아 격리시킨 후 정상운행이 가능하게 하므로 간단한 로직 변경만으로 열차 운용 안전성을 향상 및 차량 운행장애를 예방할 수 있는 효과가 있다.
