摘要
基于永磁直驱风力发电系统中风力机与永磁同步发电机的直接耦合特性,利用直流电动机模拟风力机特性,通过永磁同步发电机进行最优转速控制,实现最优功率跟踪,提出在额定风速以下的一种新型的风力模拟系统控制方法。提出功率外环、转矩内环的双闭环直流电动机控制方法模拟风机特性,并给出相应的仿真和实验验证。
Abasing on the characteristic in direct-drive PMSG wind generation that the fan couples with the PMSG directly, a new method was p to control the fan imitation system below the rating wind speed, which used the DC motor to imitate the Fan characteristic by controlling its maximum power without controlling its speed which was controlled by the PMSG. The paper proposed the DC motor double close-loops control method with the outside power loop and the inside torque loop to imitate the Fan characteristic, and gave the validation by simulation and experiment.
