Due to the increasingly widespread distribution of electrified railways, as AC-DC-AC electric locomotives are put into use in large numbers, the mixed running of AC-DCAC electric locomotives has more and more serious impacts on the power quality of the grid. Each component of the traction power supply system is equivalently processed, and the equivalent model of each part of the traction power supply system is simulated in Matlab/Simulink, and the vehicle-network joint simulation model of the AT traction power supply system is built. The rationality of the simulation model is verified according to the level of catenary pressure. On this basis, simulation analysis of locomotive power changes and typical mixed running conditions of electric locomotives are carried out to simulate and analyze the current harmonic order, harmonic content and current distortion rate of the grid side current, and the impact on the grid side current harmonic distortion Perform analysis.
