Influence factors analysis of rail potential in urban rail transit

Microelectronics Reliability, 2018
Abstract Rail potential is affected by a variety of influence factors in the urban rail transit. This paper proposes a state space average (SSA) model of the traction power system to explore the effects caused by the traction network resistance, inductance, capacitance and rail-to-ground resistance.
