Negative Impedance Converter for Reducing Rail Potential in Urban Rail Transit

Guo, Wei / Yang, Xiaofeng / Gu, Jingda / Zheng, Trillion Q.

In conventional traction power supply system (C-TPSS), the traction current returned to the substation through the running rail. Running rail current leaks into the earth forming stray current, which inevitably serious corrosions on the buried metals and endangers personal safety. In order to solve this problem, this paper proposes the negative impedance converter traction power supply system (NIC-TPSS). Based on configuration and operation principle analysis of NIC-TPSS, the working modes of negative impedance converter (NIC) are described in detail. The simulation results show that, compared with C-TPSS, NIC-TPSS can solve the stray current and rail potential problems.
