针对内置变速永磁同步发电机(IPMSG)的风力发电系统，提出了一种输出最大化控制方法。采用最大功率点跟踪控制，根据发电机转速控制发电机转矩。对IPMSG电流矢量进行控制，使发电机损耗最小，输出功率最大，同时考虑变流器容量。此外，为了提高输出功率，在高速区将逆变器的控制方式从正弦脉宽调制(PWM)控制切换为方波工作。所提出的输出最大化控制无需风速传感器和位置传感器等机械传感器即可实现。通过仿真和实验验证了所提出的发电系统的性能。
This paper proposes an output maximization control for a wind generator system with a variable speed interior permanent magnet synchronous generator (IPMSG). The generator torque is controlled according to the generator speed by employing maximum power point tracking control. The IPMSG 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 pulse width modulator (PWM) control to square-wave operation in the high-speed region to increase output power. The proposed output maximization control is achieved without mechanical sensors such as wind speed sensors and position sensors. The performance of the proposed generation system is examined by simulations and experiments.
