Research on active and reactive power's decoupled control strategy of the AC exited VSCF wind generation system

This paper focuses on the decoupled control of active and reactive power for variable speed constant frequency (VSCF) wind generation system. The principle of maximum wind power tracking for wind generation system is analyzed. Based on the mathematic model of doubly fed induction generator (DFIG) in two-phase synchronous coordinate system, the decoupled control of active and reactive power indirectly realizing maximum wind power tracking is further studied, using the method of stator field oriented vector control. An effective method of independent active power and reactive power control is proposed. Detailed simulation on MATLAB/SIMULINK verifies the feasibility and validity of the proposed control strategy.
