Abstract The far-ranging application of high-speed train with four-quadrant converter brings profound influence to the high-speed train and traction power supply grid coupling system. The study of the dynamic interaction between the high-speed train and the traction power supply grid based on impedance analysis was presented in this paper. For high-speed train four-quadrant converter using predictive current control, high-speed train equivalent model is established. Based on the control principle, the high-speed train can be equivalent to the impedance related to current loop control strategy. Based on the equivalent model, influence of traction power supply grid parameters, the high-speed train control parameters, and the number of high-speed train on the stability of the whole system are analyzed, respectively.
