ABSTRACT:
A wind electric generator employs a freewheeling clutch and an induction generator having several synchronous speeds. By selecting the synchronous speed as a function of the ambient wind speed, the generator can be made to operate more efficiently and without overloading. The freewheeling clutch which connects the generator to the wind turbine prevents the generator from acting as a motor when connected to a power grid, and wasting energy in turning the wind turbine.
