变速恒频双馈异步风力发电机动态控制扰动方法

Dynamic disturbance control methods for variable speed constant frequency doubly-fed induction wind generators

风力发电系统中,风力发电机的控制方法是个关键环节。对双馈变速恒频异步风力发电机现有的控制方法进行了研究,提出一种新颖的控制扰动方法,即将四风速模型中的合成风速在轴系模型中产生的转矩引入功率控制扰动中。

The control method of the wind generator is key to the wind power system. The existing control methods for the variable speed constant frequency doubly-fed induction wind generator were studied, and a novel method for disturbance controlling was proposed which introduced the torque generated in the shaft system model by the resultant wind velocity into disturbance control.
