Abstract :
A new simple control strategy of tracking the maximum power point in variable speed constant frequency (VSCF) wind-power generation system is proposed, through the analysis on the relationship between wind speed and the power output of the wind turbine, the decoupling between the excited current and the torque current, the requires on the generation control for tacking the maximum power point. Then, the program of this method is programmed. By this program, the feasibility of this strategy is testified. At last, a stator-flux oriented vector control model and a control system for tracking the maximum power point in VSCF wind generation is built.
