System and method for controlling a dual-fed induction generator in response to high-voltage grid events

In one aspect, a method for controlling a dual-fed induction generator (DFIG) 118 during a high-voltage grid event is provided. The method includes setting, by a controller 202, an output of a closed-loop portion of a rotor current regulator to a fixed value such that a predictive feed-forward path sets an internal voltage for the DFIG 118; and detecting, by the controller 202, a condition of high dc voltage on a dc link 224 or a condition predictive of high dc voltage on the dc link 224, and in response reduce a rotor torque producing current command to approximately zero, wherein the dc link 224 connects a line-side converter 222 connected to a system bus 216 and a rotor-side converter 220 connected to a rotor of the DFIG 118.
