| 摘 要： | 以双馈式感应风力发电机组(DFIG)为对象,分析了DFIG的建模和控制问题。该模型包括风力机模型、传动系统模型和发电机模型。提出了风力机的桨距角控制策略和发电机的转速控制策略。发电机转速控制采用dq同步旋转坐标下的矢量控制。用MATLAB/Simulink软件建立了DFIG模型,并且根据所提出的控制策略对风速随机变化以及系统电压突变时机组的运行情况进行了仿真。仿真结果验证了模型的合理性及控制策略的科学性和可行性。

| Abstract: | The paper addresses modeling and controlling of wind turbines with doubly￣fed induction generator(DFIG).A complete model of DFIG has been built,which included wind turbine model,drive train model and generator model as well.In accordance with the variation of wind speed,strategies for pitch angle control and rotational speed control were developed.For the rotational speed controller,vector control method in the dq synchronous rotational frame was employed.The model of DFIG and the proposed control strategies have been realized with the engineering software,MATLAB/Simulink.Simulation for the cases of fluctuating wind speed and sudden change in grid voltage verifies the validity of the model and the feasibility of the control strategies. |
