Title (EN) DAMPING OF TORSIONAL OSCILLATION IN A MULTI-ROTOR WIND TURBINE
(FR) AMORTISSEMENT DE VIBRATION DE TORSION DANS UNE ÉOLIENNE À ROTORS MULTIPLES
Abstract:
(EN) The invention relates to a method for damping torsional oscillations in a multi- rotor wind turbine. The multi-rotor wind turbine comprises a plurality of wind turbine modules mounted to respective support arms of the multi-rotor support structure. The method includes steps of obtaining a torsion signal indicative of a torsional movement of at least one of the support arms, determining pitch modification signals for the rotor blades of at least one of the wind turbine modules based on the torsion signal, and applying the pitch modification signals to the pitch-adjustable rotor blades of the at least one of the wind turbine module so as to dampen the torsional oscillations.
(FR) L'invention concerne un procédé d'amortissement de vibrations de torsion d'une éolienne à rotors multiples. L'éolienne à rotors multiples comprend une pluralité de modules d'éolienne montés sur des bras de support respectifs de la structure de support à rotors multiples. Le procédé comprend les étapes consistant à: obtenir un signal de torsion indicatif d'un mouvement de torsion d'au moins un des bras de support, déterminer des signaux de modification de pas pour les pales de rotor d'au moins l'un des modules d'éolienne sur la base du signal de torsion, et appliquer les signaux de modification de pas aux pales de rotor à pas réglable du ou des modules d'éolienne de façon à amortir les vibrations de torsion.
