In this paper, first, the operation principle of doubly-fed VSCF wind power generation system was analyzed, in which it especially introduced the doubly-fed generator's AC- excited system based on a structure of dual PWM converter. Then, a vector control strategy was presented, which adopted different vector control between the grid-side converter and the rotor side converter, in order to achieve various control goals. Finally, the simulation on EMTDC/PSCAD software showed that adopting this control strategy this article presented, it was able to track the largest wind power and achieve the decoupling control of wind power system's active and reactive power, ensure the stability of output power and make the wind farms operate on high power factor.
