Active & reactive power output of AC-exited VSCF wind power generator can be controlled independently by applying vector transformation control technique. The maximal wind power can be captured based on generator power control. Appropriate selection for reference power of generator is critical to the generator power control. Not only the method of active & reactive reference power was discussed in this paper. The optimal power control scheme was fully given out at last. Simulation investigation shows that not only the maximal wind power is captured, but also copper loss decreases, run efficiency and performance are greatly improved through the optimal power control, which is based on optional reference power calculation and vector control technique.
