摘　　要：为了抑制直流母线电压波动,提高交-直-交变流器的动态性能,需对其采用协调控制策略。本文对现有协调控制策略进行了总结,从功率平衡的角度,研究了交-直-交变流器的静态与动态模型。并在分析异步电动机动态模型的基础上,进行了交-直-交协调控制策略的仿真分析,仿真结果表明,这种控制算法具有直流母线响应速度更快、波动小等特点。In order to suppress the DC bus voltage fluctuations and increase dynamic performance of the back to back converters,cooperative control strategy should be adopted.This paper analyzed the existing control strategies,and the static and dynamic models of the converter were researched respectively according to the power balance principle.Simulation of the cooperative control strategy was established based on the dynamic model of the asynchronous motor,and the simulation results prove the validity of the algorithm.
