As a renewable, clean energy, wind energy has attract more and more attention. It has become a common understanding of the world to vigorously develop wind energy. In order to guarantee the safety and reliability for wind power integration operation, it is of great significance to establish an appropriate wind power generator system model and analyze its electromagnetic transient characteristics. This paper analyzes the control strategy of doubly-fed induction generator (DFIG) based wind generator. Vector decoupling control technology has been adopted to establish the mathematical model of DFIG based wind generator. Furthermore, an electromagnetic dynamic simulation model of DFIG based wind generator is established based on the platform of PSCAD/EMTDC. A short circuit fault is simulated to study the dynamic response of DFIG based wind generator. Finally, transient characteristic of DFIG is analyzed by this paper.
