Research on Wind Power System with Adaptive Speed Control of MPPT Algorithm

MPPT (Maximum Power Point Tracking) is one of the most important technologies in the wind power system. It analyses the wind power system’s model. Based on properties of wind machine’s mechanical and electrical, around the rotor dynamics and the excitation winding voltage, this paper researches the automatic tracking algorithm of rotational speed. By dynamically changing winding voltage it controls the generator reaction torque, then the rotational speed is adjusted and it develops a new nonlinear adaptive transmission control model for wind power generator. This control model can adjust the excitation winding of the alternator voltage dynamically and make wind turbines to achieve the maximum power point tracking rapidly.
