| Abstract: | The characteristics of wind turbine, permanent magnet direct drive motor model, converter control strategy and the advantages and disadvantages of various power tracking control algorithms were analyzed. An optimization of maximum power point tracking (MPPT) control based on climbing search was proposed. The permanent magnet direct drive wind power generation system model was established and the tracking effect of the control method on the maximum power point was simulated by using MATLAB/Simulink. The result showed that the tracking control method could made the system get to new operating point fast and steady when the wind tubine starts or the wind speed changes and it could capture the maximum power of the wind energy. The control method and the correctness and effectiveness of the model had been verified. |
