摘　　要：以双馈风力发电机为例,为了最大限度利用风能,增加风力发电机组发电量,简要介绍了双馈风力发电系统结构及其部分数学模型,分析了最大风能追踪的机理及最大风能追踪的实现过程,并给出了采用双馈电机定子磁链定向的矢量控制策略实现最大风能追踪的方法。最后利用Matlab/Simulink对控制策略的可行性进行仿真验证并得出该方案可行的结论。Take double-fed induction generator （DFIG） as example, to make use of wind energy for the high limit and increase generating capacity, the system structure and parts of mathematical model of DFIG were introduced, the principle and process of capture the maximum wind energy were analyzed, and the control strategy of vector control of the stator-flux oriented was given to carry out capture the maximum wind energy of variable speed constant frequency （VSCF） wind generation system with DFIG. Finally, the validity of the mathematical model and its control strategy are confirmed by Matlab/Simulink, and come to a conclusion.
