Output Maximization Control for Wind Generation System with Interior Permanent Magnet Synchronous Generator

This paper proposes an output maximization control for a wind generation system with a variable speed interior permanent magnet synchronous generator (IPMSG). The generator torque is suitably controlled according to the generator speed by employing maximum power point tracking control. The IMPSG current vector is controlled so as to minimize generator losses and maximize output power while considering converter capacity. Moreover, the converter control method is switched from sinusoidal PWM control to square-wave operation in the high speed region to increase output power. The experimental results verify the effectiveness of the proposed control method
