초록

전력설비 용량의 증가와 기술의 진보에 따라 회전기가 대용량, 고전압화 되고 있다. 그러므로 발전기 고장예방을 위한 진단시스템의 필요성이 점차 증대되고 있다. 따라서 본 논문에서는 동기발전기 불시 정지 사고에 따른 피해를 예방할 수 있는 고장진단 시스템을 개발하였다. 고장진단 시스템을 검증하기 위해 실제 동기발전기와 권선구조가 같은 소규모의 시험장비를 제작하였다. 또한 회전자권선의 단락을 진단하기 위해 홀센서와 검출시스템을 구성하여 정상상태 뿐 아니라 회전자권선 단락 등 다양한 고장상태에 대한 공극자속파형을 검출하였다.

As the increasing of capacity and technology of power facilities, rotating machines are getting higher at capacity and voltage scale. Thus the monitoring and diagnosis of generators for fault detection has attracted intensive interest. In this paper, we developed fault diagnosis system for monitoring the fault operations in bad power systems. In order to verify the performance of this fault diagnosis system, we made the small scaled testing system which has the same winding structure of the real synchronous generator. The magnetic flux patterns in air-gap of a small-scale generator under various fault states as well as a normal state are tested by hall sensors and the fault detection system.
