Dynamic Response of Grid-Connected Wind Turbine with Doubly Fed Induction Generator during Disturbances

Conference contribution, 2004

The use of the Doubly-fed Induction Generator (DFIG) in large wind turbines (MW-class) is growing rapidly. In order to investigate the dynamic response of a wind turbine with DFIG connected to the power system during grid disturbance, a model has been developed. This model includes aerodynamics, the mechanical drive train, the induction generator as well as the control parts. The response of the system during grid disturbances is studied. An inclusion of saturation effect in the generator during faults is included as well.
