직류전기철도 시스템에서 레일전위 억제 장치가 다른 역사의 레일전위에 미치는 영향 분석

초록

Nowaday, The rise of rail potential leads to damage for human and equipments in DC feeding system. In order to prevent the problems, this paper suggests rail potential limit device and addresses what operation of the device has an effect to the entire system. This paper simulates DC feeding system before and after the application of the device and analyzes the results in various cases. The results show when the device operates, rail potential of other places changes. So this paper presents effective operation of rail potential limit device.
