Abstract
The protection algorithm of DC line grounding for the subway is proposed in this paper. Compared to the conventional protection algorithm, the proposed algorithm has a advantage that can distinguish the difference between service line and faulted line. The contents of the proposed algorithm are by using blocking filter and PLC(Power Line Carrier). Results of the simulation show that the proposed algorithm is very useful.
