摘　　要：从风力机和双馈感应电机(DFIG)的基本原理入手,建立了风力机的数学模型,并建立了基于定子磁链定向的双馈风力发电机动态数学模型;针对DFIG双闭环控制系统功率外环PI调节器自适应能力较差的缺点,提出了用Fuzzy-PI控制器代替功率外环PI调节器.与传统PI控制器相比,Fuzzy-PI控制策略对有功功率跟踪速度快、超调量小,仿真结果也表明了Fuzzy-PI控制器具有优良的动、静态性能,并验证了控制策略的可行性.Starting with the principles of wind turbine and doubly-fed induction machine,the mathematic model of wind turbine is built,so it＇s the dynamic model of doubly-fed induction machine based on stator-flux oriented.According to the PI regulator＇s poor adaptive ability,it＇s proposed to use Fuzzy-PI controller in stead of power external ring controller.Comparing with traditional controller,the Fuzzy-PI control strategy has faster speed and smaller shoot.The simulation results shows the good characteristics and the feasibility of control strategy is verified.
