During the period when the active crowbar is activated, the DFIG operates as a wound rotor induction generator
(WRIG) with increased rotor resistance but no control over both active and reactive power output.
The adaptive control system aims to maintain a constant voltage at the induction generator
Doubly Fed Induction Generator
. The one-phase equivalent electric circuit of the DFIG rotor and stator is shown in Figure 2.
Wind power captured from the wind turbine transfers into electric power through the gear box and the induction generator
. The induction generator
is quite special since it has a dual converter which is made of electric devices such as IGBTs.

The wind turbine model is composed of three sub models connected together, aerodynamic rotor, drive train and induction generator
The S111-140m and S120-140m WTGs feature the time tested Doubly Fed Induction Generator
(DFIG) technology that efficiently integrates wind turbines into the utility network, to meet the grid requirements.
