Abstract：Traction power supply system is an important subsystem of high-speed railways.Its safe and efficient operation is an important guarantee for the reliability of the high-speed railway.This article discusses the detail mathematical and circuit equivalent model of traction power supply system,builds a all-paralleling AT traction power supply simulation system based on DDRTS (Digital Dynamic Real-Time Simulator),analyzes and compares various types of faults with practical test.Simulation and experimental tests show that the system can accurately simulate current distribution under different types of actual faults and the different locations of actual faults.The system can provide the important theoretical basis for engineering design and application.
