METHOD AND SYSTEM FOR DETERMINING A MASS CHANGE AT A ROTATING BLADE OF A WIND TURBINE |
摘要 |
It is described a method for determining a mass change at a rotating blade of a wind turbine, the method comprising: measuring a vibration quantity representative of a vibration of the wind turbine; measuring an azimuthal quantity representative of a rotation angle of the blade; determining a frequency quantity representative of a vibration frequency of the blade from the vibration quantity and the azimuthal quantity; determining the mass change at the blade based on the frequency quantity. |
