DFIG with simplified crowbar

simplified crowbar of doubly fed induction generator

Crowbar in this model is not built using IGBTs or ideal switches.
The cut-in and cut-out of crowbar circuit is modelled by
changing the reference voltages of rotor-side converter.
The model was created using MATLAB R2010a.
The control strategy is the most common decoupling
algorithm and MPPT, you can update it using your own strategy.
