According to the dynamic characteristics of doubly-fed induction generator (DFIG) which is changing with the wind speed, the dynamic mathematical models of DFIG wind turbines major subsystems’ have been established, which includes the aerodynamic subsystem, drive train subsystem and generator subsystem. The whole nonlinear time-varying parameters dynamic mathematical model would be obtained to integrate the major subsystems’ dynamic mathematical models, and the whole linear time-varying parameters dynamic mathematical model can be obtained to linearize the whole linear time-varying parameters dynamic mathematical model. To take the 2MW DFIG wind turbine as example, the proposed model is validated by the study on the dynamic characteristics of DFIG with wind speed variation, and the results show that the proposed model could provide a theoretical support for optimal control of the DFIG wind turbines.
