摘　　要：双馈异步风力发电(doubly-fed induction generator简称DFIG)技术是目前风力发电的主导技术。针对DFIG的功率解耦控制,提出了基于最优估计的最大功率控制方法,解决了传统控制技术中最大功率捕捉的问题。设计了基于该方法的MATLAB仿真系统。从仿真实验结果可以看出该方法的正确性和实用价值。Doubly-fed induction generator（DFIG） is the leading technology in wind power currently. In this paper, decoupling control of DFIG was studied and a new method based on optimal Estimation was used to DFIG system＇s maximum power control. And compared with the traditional control method, the new method has a good characteristic in maximum power point tracking. In this paper, a simulation system based on this method was designed in the MATLAB, the experimental results of simulation could be seen that the method was correct and has practical value.
