The decoupling control for active and reactive power in doubly-fed wind generators is crucial to variable speed constant frequency (VSCF) wind power generation system. The realization method of the stator flux oriented control was put forward based on analyzing the deeoupling control rules for the active and reactive power of the doubly- fed induction generator ( DFIG), and the control strategy was simulated by using Matlab. The results proved the con- trol strategy efficient.
