Novel rotor-side control scheme for Doubly Fed Induction Generator to ride through grid faults

A simplified transient model of the Doubly Fed Induction Generator (DFIG) is used to investigate the effects when the voltage sags impose to the DFIG generation system. It is identified that the symmetrical transient voltage sag creates a DC component in the magnetic field which causes over currents in both the stator and rotor windings. The characteristics of the DC flux component are investigated and new control strategy is presented. Computer simulation is used to verify the expanded ride-through capability of the novel strategy.
