The VSCF wind turbine as the research object, according to the national standard (GB/Z19963 - 2011), in the analysis of double fed wind turbine structure based on the established mathematical model and control model of dfig. In order to obtain the optimal benefits for wind power, active power control, the torque and pitch angle joint control strategy, and Simulation of joint control torque and pitch angle; for reactive power control, gives the unit power factor control optimal strategy. Simulation and experiment show that this method achieves good control effect.
