Abstract
Wind turbine comprising: a tower () and a nacelle () housing a generator () driven by a wind rotor; measuring devices of at least wind speed V, generator speed Ω, pitch angle θi of each blade, power P, wind turbine accelerations in two perpendicular directions Ax, Ay, yaw angle Yw; azimuth position of the wind rotor AZ in which the control system connected to said measuring devices and to at least pitch and torque control actuators is also arranged for performing an active pitch angle regulation when the wind turbine is in an idling situation above Vchanging the pitch angle θi of each blade for minimizing the wind turbine vibrations depending at least on the measured values of wind speed V, wind turbine accelerations Ax, Ay in two perpendicular directions, yaw angle Yw, azimuth position of the wind rotor AZ and pitch angle θi of each blade.
