Faults and reliability analysis of negative resistance converter traction power system

摘要

To analyse the reliability of negative resistance converter traction power system (NRC-TPS), this paper discusses the short-circuit and open-circuit faults of its components. NRC-TPS is adopted to mitigate rail potential and stray current for the urban rail transit. The simulation results show that NRC-TPS can still mitigate rail potential and stray current at most faults. NRC-TPS is reliable for the urban rail transit to solve rail potential and stray current issues.
