摘要：双馈异步电机运行控制的核心就是其变换器的控制。首先阐述了双馈异步电机双PWM变换器的工作原理及对应控制策略，随后建立了双馈异步电机及转子侧变换器的模型，继而分析了网侧变换器的控制模型，并据此分别设计出了结合前馈解耦的变换器双闭环控制结构框图。在Matlab/Simulink平台下，建立1.5MW双馈异步电机用双PWM变换器仿真模型，仿真结果实现了双馈异步电机用双PWM变换器控制的控制目标，验证了仿真模型和控制策略的可行性和正确性。

Abstract: The core of operation control of the doublyfed induction motor is the control of converter. Firstly the working principle and the corresponding control strategies of dualPWM converter used in doublyfed induction motor were expounded.Then the model of the doublyfed induction motor and the rotor side converter are established ,and then the control model of the network side converter was analyzed. And accordingly,combining feedforward decoupling,the converter double closed loop control structure diagrams are designed.In Matlab/Simulink platform, the dualPWM converter used in doublyfed induction motor whose power is 15 MW was established, the simulation results achieved the control targets of the dualPWM converter used in doublyfed induction motor and validated the feasibility and correctness of the simulation model and control strategy.
