| 摘 要： | 根据矢量控制方法,基于积分切换函数的滑模变控制,设计了变速恒频风力发电机的并网控制策略,使系统在全局范围内对参数摄动和外部扰动都具有很好的自适应能力.在控制器中引入了饱和函数,降低了控制增益的大幅切换,保证了定子电压的稳定性.对并网前的动态响应、并网时的过渡过程以及该控制方法对外部扰动的不灵敏性,用PSCAD做了相应的仿真研究,并与传统的PI控制进行对比. |
| 关 键 词： | 滑模控制 并网 双馈风力发电机 鲁棒性 |

| Abstract: | According to the vector control method,based on sliding mode variable structure control of integral switching function,designs the strategy to control variable speed constant frequency doubly-fed wind generator connecting electric grid.This strategy makes system have good self-adaptability to the parameter perturbation and external disturbance in global range.Introduces the saturation function into controller,reduces the wide-range switch of control gain,ensures the stability of stator voltage.Simulates the dynamic response before connecting electric grid,transient process at connecting electric grid,the robustness to all kinds of external disturbance with PSCAD,compares this strategy with traditional PI control. |
| Keywords: | sliding mode control connecting electric grid doubly-fed wind generator robustness |
