摘要：针对双馈风力发电机组网侧系统的复杂性，稳态性差等弊端，提出一种滑模变结构控制方法，将此控制策略应用到网侧PWM变换器进中。在Matlab/Simulink仿真软件中，将此方法与传统的PI控制进行比对。将滑模控制方法在双馈风力发电机组实验平台中进行测试。结果表明，采用滑模变结构控制策略使得直流母线上的电压更加稳定，而且系统的响应速度也得到了提高。

Abstract: Aiming at the disadvantages of the grid side system of DFIG, such as complexity, poor stability, etc. A sliding mode variable structure control method was proposed to apply the control strategy to the grid side PWM converter. In the Matlab/Simulink simulation software, this method was compared with the traditional PI control. The sliding mode control method was applied to the experimental platform of doubly fed induction generator (DFIG). The results show that the sliding mode variable structure control strategy makes the voltage on the DC bus more stable, and the response speed of the system is also improved.
Key words: doubly fed wind turbine generator; set smvs; DC bus
