摘要
首先研究风力发电机组的空气动力特性,确定风力发电机组的最优工作点以及在各种风速下的控制策略;然后参照风能利用系数的特点确定自寻优控制策略;最后讨论了发电机的两种控制方式,即转速控制方式和力矩控制方式,结合空气动力学确定对双馈电机所采取的控制环节以实现最优工作点跟踪。
The wind turbine aerodynamics, optimal operation point of the generator and control strategy under variable wind speed were studied. Then the self-optimization control strategy was decided according to the feature Of the wind power coefficient. Finally two methods of controlling the doubly fed induction generator were discussed, which could track the optimal operation point.
