Abstract
In order to analyze correctly the effect of different models for induction generators on the transient performances of large wind power generation, Wind turbine driven squirrel cage induction generator (SCIG) models taking into account both main and leakage flux saturation and skin effect were proposed. A two-mass lump equivalent model of a wind turbine shaft system was also used to considering shaft flexibility. The transient behaviors of the wind generator system with the different models were investigated and compared with the software platform Matlab/Simulink, under conditions of a large mechancical disturbance and a grid voltage sag, respectively. Simulation results have shown that the effect of the flux saturation is obvious on the transient behavious of the wind power generator system, especially for a grid voltage sag studies.
