METHOD AND SYSTEM FOR DETERMINING A MASS CHANGE ON A ROTATING BLADE OF A WIND TURBINE |
摘要 |
A method for determining a mass change at a rotating blade of a wind turbine is provided. The method includes 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, and determining the mass change at the blade based on the frequency quantity. |
