Abstract: Put forward a control method to maximizing the system output, for a small wind energy conversion system composed of a new type of permanent magnet synchronous generator(PMSG).With this method, the wind turbine torque vs rotate speed characters could be indirectly controlled via adjusting the machine electromagnetic torque vs rotate speed characters,and the wind turbine operation with the optimum tip-speed ratio(TSR)and the maximum power point(MPP)was automatically tracked.A 1000W power conditioner prototype was designed and constructed.The experimental results indicate the effectiveness of this method during maximum power tracking.
