Structure Scheme and Control Strategy Design of Advanced Traction Power Supply System

The traditional traction power supply system has electric phase separation, which restricts the train speed. At the same time, negative sequence, harmonic and reactive power problems will affect the safety of system operation. Firstly, this paper studies the structure scheme of advanced traction power supply system. Then the control strategy and modulation strategy of the system are designed. Then the Matlab/Simulink simulation model of advanced traction power supply system is established. Finally, a low-power experimental platform was built to verify. The simulation and experimental results verify the feasibility of the advanced traction power supply system.
