摘要： A rotor blade assembly for mitigating stall-induced vibrations of a wind turbine during standstill includes at least one protrusion secured to the leading-edge of a rotor blade and defining an extended leading edge. The protrusion(s) wraps around a portion of the rotor blade from the suction side to the pressure side of the rotor blade. The protrusion(s) has a root-side face and a tip-side face disposed opposite thereof. The root- side face is arranged at an angle relative to a chordwise reference line. The angle is greater than zero degrees and less than or equal to 45 degrees with respect to the chordwise reference line. The protrusion(s) is configured to affect a chordwise airflow and thereby mitigate a stall-induced vibration.

摘要： A method for the calculation of a wind turbine blade deflection is described. The method utilises a known blade modal profile in the calculation of the blade deflection, such that the a priori knowledge of the blade excitation modes can be used with a simple distance measurement to determine the blade deflection shape. The calculated blade deflection can then be used as an input to control wind turbine operation, e.g. where it is likely that the deflected blade might result in a tower strike.
