The simulation platform of 24-pulse rectification and supply system based on train drive system was established, and the principle of phase-shifting of 24-pulse rectifier was analyzed and modeled. The vector control traction drive system based on SVPWM three-level inverter As a load, the simulation of the operation of the motor at ideal mains power and 24-pulse power is simulated. At the same time, the harmonic and DC voltage of the grid under various operating conditions are analyzed. The simulation results show that the 24-pulse power supply is good, and the co-simulation platform can effectively analyze the interaction between AC side, DC side and train operation.
