Abstract
In the wind power generation system, the Doubly Fed Induction Generator (DFIG) has many advantages and has become a major model of wind energy development and utilization currently. However, the operation control strategy of wind power system based on the ideal grid environment cannot adapt to the requirements of the actual grid conditions. In this paper, firstly, the structure and operation principle of the DFIG system are analyzed, and the mathematical model of DFIG in three-phase static coordinate is established. Then, a PWM converter control simulation method is built on the MATLAB/Simulink platform, and the proportional-integral (PI) vector control strategy is used to carry out simulation experiments. The effectiveness of the proposed control strategy is verified by the final results.
