Abstract

In this paper, according to the traction calculation, a stray current dynamic distribution model of multi-locomotives running under different operation conditions was established which based on the metro locomotives stray current static distribution model, then analyzed the dynamic distribution of rail potential and stray current under different operation conditions. The simulation results show that: locomotives operation conditions have a significant influence on the distribution of rail potential and stray current. The more locomotives running, the greater value and stronger fluctuation of stray current.
