- 13 - Abstract Minimization Of The Effects Of Yaw Oscillations In Wind Turbines 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 settings 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. H-1192
