- Abstract:
- A single-phase and three-phase combined transformer power supply system applied to electrified railways was studied. The structure and working principle of the single three-phase combined power supply system, as well as capacity utilization and negative sequence characteristics, were analyzed. The transformer of the single three-phase combined power supply system was first simulated using Matlab/Simulink, and the simulation results showed that the structure and principle of the single three-phase combined power supply system were in line with theoretical analysis. Secondly, Simulation verification was conducted on the same phase power supply system composed of combined transformers, and the simulation results showed that the compensation scheme was effective
