Abstract[English]
A first aspect of the invention provides a method of monitoring a blade of a rotor of a wind turbine, the method comprising: obtaining a bending value by measuring bending of the blade as the rotor rotates; obtaining an azimuth value associated with the bending value by measuring an azimuth angle of the blade; determining a cosecant of the azimuth angle; determining a gravity component on a basis of the bending value and the cosecant of the azimuth angle; and using the gravity component to determine whether a blade weight anomaly exists and generate a corresponding output.[French]
Un premier aspect de l'invention concerne un procédé de surveillance d'une pale d'un rotor d'une éolienne. Ledit procédé comprend les étapes consistant à : obtenir une valeur de flexion par mesure de la flexion de la pale lorsque le rotor tourne ; obtenir une valeur d'azimut associée à la valeur de flexion en mesurant un angle d'azimut de la pale ; déterminer une cosécante de l'angle d'azimut ; déterminer une composante de gravité sur la base de la valeur de flexion et de la cosécante de l'angle d'azimut ; et utiliser la composante de gravité pour déterminer si une anomalie de poids de pale existe et générer une sortie correspondante.
