The detailed model structure and generic model structure of doubly-fed induction generator (DFIG)-based wind turbines are compared. It is found that the capacitor

grid-side converter controller

and stator and rotor dynamics of the generator are ignored in generic model. Based on the eigenvalue technology and time-domain simulation analysis

it is reasonable to neglect the dynamics of capacitor and grid-side converter controller. The analysis also shows that negligence of stator and rotor dynamics of the generator in the generic model only has impact on the fast dynamics of rotor-side controller. This paper further indicates that the generic model can also ignore the dynamics of current control inner-loop of rotor-side controller. The dynamic behaviors of different drive system models

and the impact of rotor-side controller parameters on the dynamic behavior of DFIG-based wind turbines is also studied. This work is supported by National Basic Research Program of China （973 Program）(No. 2013CB228204)
