摘　　要：从交流励磁双馈发电机的数学模型出发,介绍了双馈发电机定子磁链定向矢量控制技术,推导了变速恒频双馈风力发电机空载并网的控制策略。在Matlab/Simulink环境下建立了系统模型,进行了发电机空载并网、最大风能追踪、有功无功独立调节等情况的仿真研究,仿真结果验证了控制方案的可行性。According to the mathematical model of AC excited doubly fed induction generator （DFIG）, this paper presents the principle of stator flux oriented vector control of DFIG. The no load grid-connected control strategy for the DFIG was made. Several simulation models such as no load grid-connected, maximum power point tracking, independently control of active and reactive power was established in Matlab/Simulink. The simulation results validated the feasibility of the control strategy.
