Title (EN) DAMPING WIND TURBINE TOWER OSCILLATIONS
(FR) AMORTISSEMENT D'OSCILLATIONS DE TOUR D'ÉOLIENNE
Abstract:
(EN) Damping wind turbine tower oscillations It is described a method for damping a side-side oscillation (5) of a tower (1) of a wind turbine (20) having a generator (29) connected to a converter (33), the method comprising: measuring an acceleration value (51) of the tower (1); determining, based on the acceleration value (51), at least one frequency value (53) of at least one tower oscillation mode, including a second tower oscillation mode; controlling the converter (33) of the wind turbine (20) based at least on the acceleration value (51) and the frequency value (53).
(FR) L'invention concerne un procédé d'amortissement d'oscillations côté latéral (5) d'une tour (1) d'une éolienne (20) ayant un générateur (29) connecté à un convertisseur (33). Le procédé comprend: la mesure d'une valeur d'accélération (51) de la tour (1); la détermination, sur la base de la valeur d'accélération (51), au moins d'une valeur de fréquence (53) d'au moins un mode d'oscillation de tour, comprenant un second mode d'oscillation de tour; la commande du convertisseur (33) de l'éolienne (20) sur la base au moins de la valeur d'accélération (51) et de la valeur de fréquence (53).
