Abstract
A method of operating a wind turbine comprising a generator in the event of a voltage dip is disclosed. The method comprises detecting an end of the voltage dip, determining an acceleration of a rotor of the generator, and increasing a torque of the generator when the end of the voltage dip is detected according to a selected torque profile. The selected torque profile is selected from a plurality predetermined torque profiles, wherein the predetermined torque profiles describe torque as a function of time. The selected torque profile is selected based on the determined acceleration of the rotor of the generator. Also provided are wind turbines configured for such methods.
