This paper discribes the operating characteristics of a mechanical governor installed for blade pitch control, rotor speed control and generator power control in a variable-speed wind turbine generator system (VWTG). The VWTG is equipped with a 2-bladed teetered rotor of 15-meter in diameter and a 22-kW generator. Since the centrifugal forces of the weight-elements of the governor are utilized as direct control forces, the control are performed firmly and rapidly. The operation data show that the governor works satisfactorily to regulate rotor rotational speed and the generator power within the designed range of operation.
