Abstract :
In order to investigate the transient response of doubly fed induction generator (DFIG) under grid disturbances, an accurate model is required. In this paper transient response of DFIG during voltage sag considering saturation effect of leakage flux for different order models is simulated. It´s shown that if the saturation effect is neglected, simulation result display less current than real one. Then, rotor over-current due to voltage sag and factors that affect it is investigated using saturated model.
