模块化多电平铁路功率调节器滞环控制策略
Hysteresis Control Strategy for Modular Multi-level Railway Power Conditioner
摘要
Abstract
To overcome the shortcomings of modular multi-level railway power conditioner(MRPC)in controlling the power quality of traction network,such as complex control,a large amount of calculation load and complex modulation strategy,a DC hysteresis control strategy for modular MRPC is constructed based on two-level hysteresis loop control in this paper.Under the recent level approximation strategy,the port voltage is output to offset the high voltage on the trac?tion side;meanwhile,the current error value on the compensation side is used to modulate the pulse signal from the sub-module of bridge arm and thus realize astatic track of compensation current.This hysteresis control strategy has the advantages of simple debugging,a small amount of calculation load and strong robustness,etc. Simulation results verify the correctness and effectiveness of the proposed control strategy.关键词
