Abstract
L'invention concerne un procédé d'amortissement d'oscillations de tour d'une éolienne à zone de rotor variable. L'éolienne comprend une tour, un rotor ayant une ou plusieurs pales de rotor qui sont disposées de manière articulée à un angle de pivotement réglable, l'angle de pivotement étant réglable en fonction d'une force de pivotement variable ou d'un moment de pivotement fourni par un actionneur de pivot. Le procédé comprend la détection d'une oscillation de tour, et en fonction de l'oscillation de tour détectée, la réduction ou l'augmentation de l'angle de pivotement pour obtenir une réduction de l'oscillation détectée.
