摘要
利用双馈感应电机具有在转速不断改变的条件下输出频率恒定的电压信号的优点,使得双馈感应电机在分布式发电领域得到广泛的应用。在介绍双馈感应发电系统的基本结构及其控制方法的基础上,重点对独立运行条件下双馈感应发电机定子侧输出电压的PI控制技术进行了详细的阐述。通过采用传统的矢量变换与性能优良的PI调节器相结合的控制技术,在Matlab/Simulink平台上仿真实现定子侧三相电压的稳定输出。证明定子电压采用双闭环结构进行控制,最终得到理想的电压幅值和频率。
Because of the advantage that it can output constant frequency signal for variable rotor speed, Doubly Fed Induction Motors are wildly used in distributed generation. The structure of Doubly Fed Induction Generation （DFIG） system and control theory were described in this paper, and the interpretation for PI control technology stan- dalone DFIG were given more attention. On the foundation of vector conversion control technology, and connected with advanced PI control technology, the stator voltage can be regulated stably based on Matlab/Simulink simulation platform. The control of stator voltage adopts double-closed loop structure for the perfect peak voltage and frequency.
