직류급전시스템에서의 누설전류 및 레일전위 관리방안 연구

초록

This paper presented a rail potential and leakage current model using propagation equation based on shunt energization model for analysing rail potential and leakage current according to the grounding scheme in DC feeding system. we analyzed the change of rail potential and leakage current due to the change of parameters such as rail resistance, conductances between rail and earth, return current and distance between substations in case one electric car runs between substation. And we investigated a management method of rail potential and leakage current to satisfy of the international standards
