Pulse Width Modulation technology is widely used in China High-Speed Railway. The harmonic distribution caused by this technology is more extensive, the characteristic harmonics are more obvious, it increases the possibility of the network-train coupling resonance in the traction power supply system(TPSS). In this paper, the multi conductor chain network model of traction network is established based on the complex depth model and Carson theory, and the dynamic simulation model of train is established. According to the theoretical calculation, a simulation is built in Matlab to alalysis the impedance charactics of TPSS, the parameter sensitivity of autotransformer(AT) interval distance, equivalent inductance, power supply length and the harmonic amplification rule when the train arrive the end of the power supply interval. Finally, the real-time simulation of TPSS is carried out on the RT-lab, and it is proved that the analysis of the impedance characteristic has certain guiding significance to avoid the network-train coupling resonance.
