Abstract :
The use of the Doubly-fed Induction Generator (DFIG) in large wind turbines is growing rapidly, the wind farms are today required to participate actively in grid operation by an appropriate generation control. The study focuses on the direct power control (DPC) of the DFIG active and reactive powers (DPC) using the so-called sliding mode control (SMC). A model has been developed, including the mechanical, the induction generator and the control parts. The DFIG control strategies and the response of the system during grid disturbances are tested with large grid disturbances due to voltage sags.
