| 摘 要： | 传统双馈风力发电机(DFIG)控制存在抖振现象,容易造成系统的不稳定。为了减轻控制抖振现象,提高控制的稳定性,在分析了DFIG动态特性的基础上,建立了DFIG的数学模型,设计了超螺旋二阶滑模控制器,并研究了突变风的情况下滑模控制器的控制性能。通过MATLAB/Simulink工具进行了仿真验证。仿真结果证明:滑模控制器具有良好的最优转矩跟踪能力和无功调节能力,与一般的控制方法相比鲁棒性较强,转子控制电压连续,控制产生的抖振可以大幅减轻,系统的稳定性大大提升。

| Abstract: | Traditional doubly fed induction generator (DFIG) control had chattering phenomenon, which was easy to cause instability of the system. In order to reduce the chattering phenomenon of control and improve the stability of control, the mathematical model of DFIG was established on the basis of analyzing the dynamic characteristics of DFIG. The superhelix secondorder sliding mode controller was designed, and the control performance of the sliding mode controller in the case of sudden wind was studied. Simulation was carried out using MATLAB/Simulink. Simulation results showed that the sliding mode controller had good abilities of tracking optimal torque and adjusting reactive power. Compared with general control methods, it had strong robustness of rotor continuous voltage control. Furthermore, this sliding mode controller could significantly reduce the chattering and greatly improve the stability of the system. |
