摘要

The present invention relates to a ?l ground fault protection relay system for a DC traction power supply system and a method of controlling the relay system, which can predict feeders, in which a ground fault is occurring when a ground fault accident occurs in the DC traction power supply system, and can primarily trip the predicted feeders, thus minimizing damage caused by the accident, and promptly and precisely determining the feeder in which the ground fault is actually occurring. The ?l ground fault protection relay system for a DC traction power supply system according to an embodiment of the present invention includes one or more ground fault sensing units (20a, 20b, and 20c), one or more feeder identification units (30a, 30b, and 30c), and one or more ground fault feeder control units (40a, 40b, and 40c).
