Abstract :
In order to investigate the transient response of doubly fed induction generator (DFIG) under grid disturbances, an accurate model is required. This paper uses available DFIG models and investigates the influence of various model parameters and simplifications for both mechanical (two-mass model) and electrical (saturation) subsystems on DFIG based wind plant transient response. Then, the factors that affect stator over current due to voltage sag are investigated using complete model.
