摘　　要：提出了一种双馈风力发电系统并网控制策略。给出了双馈电机在同步旋转坐标系里的数学模型,采用电网电压定向矢量控制对双馈电机的数学模型进行了简化。结合交流励磁双馈电机风力发电系统并网的实际情况,提出了分段并网控制策略,给出了各个控制器的设计方法,在实验室所搭建的变速恒频双馈电机风力发电试验平台作了相应的验证性试验。试验结果证明,所提出的方法可以使双馈电机实现平滑并网。A novel grid connection strategy of double- fed induction generator （DFIG） wind generation system is proposed. Mathematical model of DFIG in synchronous coordinale system were made. Grid voltage oriented vector control strategy was implemented to control DFIG. Stagewise control stralegy was proposed for connecting DFIG to the grid. Overall controllers were designed and implemented. The control strategy was implemented on a simulation platform of AC excited DFIG wind generation system. Experiment results verified the proposed control strategy.
