The developing trend of wind power generating system was introduced. Comparison was made among the contemporary wind power generating groups. A vector control system and mathematical model of doubly fed induction generator were analyzed and a stator flux linkage orier＇ed vector control model was given accordingly. The control methods of the reactive power, the torque, and uncoupling control of the rotor current were described, and a system block diagram based on PID closed loops was given. The whole system was simulated by using the Simulink tool of Matlab software based on the mathematic model of DFIG.
