Abstract

Complex control progress, large amounts of calculation and complex modulate strategy is the problems when modular multi-level railway power conditioner (MPRC) improves the quality of electric energy in traction network. In order to overcome these problems, this paper constructed the dc hysteresis control strategy of MPRC on the basis of dc-ac electric hysteresis control strategy. In this strategy, the closest electric level approximation principle is used to output port voltage to offset high voltage on the traction side, and the current error is used to modulate sub-module pulse signal of bridge arm on the compensation side to realize the no static tracking of compensation current. The new hysteresis control strategy has some advatages: easily debugging, small amount of calculation, strong robustness. The simulation results verified the correctness and effectiveness of the proposed control strategy.
