Abstract:In order to solve the electrified railway harmonic pollution problem and a high negative sequence content in V/V traction power supply system,a railway static power conditioner is used.After analyzing its basic structure and compensation principles,a proposed inner loop current control method deadbeat control is focused on and the combination forecasts are repeated.The introduction of this method is such that the inner ring can improve the robustness of the system and reduce the control deviation of the delay and the inductor current distortion,and suppress harmonic current.A simple and convenient PI outer loop control engineering to is selected ensure the stability of RPC DC side.Finally,the simulations proves the correctness of the method.
