Doubly fed induction generator (DFIG) wind turbines are widely utilized in large wind plants. Research of the dynamic behaviors of DFIG wind turbine is of great importance. In this paper

the 8th

5th and 3rd order models of DFIG wind turbines are discussed respectively. The 8th order model includes the complete drive train

the stator and the rotor models. The 5th order model contains the stator and the rotor models

as well as a reduced drive train model. The 3rd order model

with the stator transients being neglected

comprises the rotor model and a reduced drive train model. These three types of DFIG wind turbine are modeled in MATLAB/Simulink software package. Two cases of simulation are conducted to verify the models and compare their responses. The simulation results demonstrate that the 8th order model is the most precise model

but needs the longest simulation time; the 3rd order model is a good approximation and the most timeeffective; the 5th order model is suitable for most studies that require both fast computation speed and relatively high precision.
