    摘要: A wind turbine including a control system and at least one wind turbine blade having a pressure measurement system is disclosed. The pressure measurement system includes a pressure probe that provides a measurement of inflow angle to the control system. The control system adjusts the blade pitch angle of the at least one turbine blade in response to the inflow angle measurement to improve energy capture. The pressure probe is mounted by a probe support structure at a predetermined position from the leading edge of the at least one wind turbine blade.

    摘要: The present invention relates to a method of controlling the aerodynamic load of a wind turbine blade by controlling the tip speed ratio (TSR) and/or blade pitch setting of the wind turbine blade so as to optimize power production. A wind turbine blade undergoes an aero-elastic response including deflection and twist that is a function of the blade loading. The blade loading is dependent on the wind speed, TSR, and pitch setting. The aero-elastic response requires a different TSR and/or pitch to be selected throughout the power curve in order to maintain the optimum power production and to improve energy capture.
