Abstract:
A wind energy converter configured for transmitting power to an electric grid includes a variable ratio gear system mechanically coupled between a rotor and a generator. A control system is configured to mechanically control a rotational speed of the generator so that, during a low voltage event, the wind energy converter can continue to operate and supply power to the grid.
