Patent ID: 8680700

Claim:
Wind turbine comprising: a tower ( 13 ) and a nacelle ( 21 ) housing a generator ( 19 ) driven by a wind rotor formed by a rotor hub ( 15 ) and at least one blade ( 17 ); 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; a control system connected to said measuring devices and to at least pitch and torque control actuators, the control system being arranged for performing a regulation of the wind turbine according to a predetermined power curve ( 25 ) for wind speeds below the cut-out wind speed V out ; characterized in that the control system is also arranged for performing an active pitch angle regulation when the wind turbine is in an idling situation above V out changing 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 in two perpendicular directions Ax, Ay, yaw angle Yw, azimuth position of the wind rotor AZ and pitch angle θi of each blade.
