Abstract: Yaw (fishtail) oscillations in large wind turbines (10) are minimized by damping provided by a drive motor (65) connecting the turbine to the supporting tower (50) therefor at, for example, a yaw bearing (45). The drive motor drives the wind turbine in yaw and maintains desired yaw setting of the turbine. The motor is also capable of being driven by yaw oscillations of the wind turbine and in being so driven, dissipates the energy of such oscillations.

Abstract: Yaw trimming in large wind turbines is achieved by laterally offsetting the turbine yaw axis from the axis of rotation of the hub.

Abstract: A wind turbine adapted to rotationally drive a load such as an electric power generator 50 includes in the turbine drive train, resiliently mounted gearing 55 which isolates and damps the load from drive train disturbances caused by wind gusts and wind stream dyssemmetry and inherent torsional vibration without assistance from modulation of turbine blade pitch.

Abstract: A variable speed wind turbine includes a frequency converter which converts variable frequency AC from a turbine driven AC generator to fixed frequency AC for delivery to a power grid. The frequency converter is typically an electronic cycloconverter or rectifier-inverter and is also used to control the power flow from the AC generator to the grid which thereby controls the air gap torque between the generator stator and rotor. The turbine speed is maneuvered to increase efficiency by precisely controlling the air gap torque according to a schedule defining sensed generator speed versus sensed generated power.
