A method and apparatus for converting wind generated electricity to constant frequency electricity for supplying it to a utility grid. use a wind turbine generator having a doubly fed induction generator. Above the synchronous speed of the generator, the electricity from the rotor is converted to direct current (dc) electricity and the de electricity is converted back to alternating current (ac) electricity at a fixed unity power factor. Below synchronous speed, electricity flows to the rotor from the utility grid also at a fixed unity power factor. The current of the ac electricity is adjusted to be in phase with the utility grid voltage, wherein the ac electricity is maintained substantially at unity power factor.
