Study on the New Maximum Power Tracking for Variable Speed Wind Generator system


In view of the problems that tip speed ratio (TSR) control can't achieve maximum output power and hill climb searching (HCS) control could not meet both rapidity and accuracy at the same time, this paper proposes a novel wind energy maximum power point tracking (MPPT) approach combining TSR control with search algorithm. The approach has not only the characteristics of simple and easy to implement, but also has advantages of fast convergence and high precision to mode search control. Speed tracking controller is designed by the feedback linearization to quickly track to optimized speed. According to the results of experimental tests, the control strategy could achieve maximum output power with the fast dynamic response.
