ABSTRACT:
A wind turbine drives the squirrel-cage rotor of a capacitively excited induction generator. The amount of excitation is controlled in accordance with the output voltage of the stator and hence the speed of the wind turbine. The generating system is capable of operating at high efficiency over a wide speed range, since the electrical output frequency is allowed to vary with the rotor speed. The electrical power supplied by the induction generator is used for heating purposes within a nearby building.
