Abstract
(EN) A hybrid damping module, a vibration suppression device, a vibration suppression method, and a wind turbine set. The hybrid damping module comprises a first damping unit (8). The first damping unit (8) comprises a rotor portion (8a) and a stator portion (8b) that is provided parallel to the rotor portion (8a). The rotor portion (8a) is configured to capable of rotating relative to the stator portion (8b) so as to generate electromagnetic damping. A flow passage is formed in at least one of the rotor portion (8a) and the stator portion (8b). The hybrid damping module comprises a second damping unit (10) comprising a liquid damper. The liquid damper communicates with the flow passage and forms a circulation loop. A liquid (10p) in the liquid damper can cyclically flow in the circulation loop. In the hybrid damping module, a combined vibration suppression solution that combines a TMD and TLD is provided. By means of using a TMD and TLD in combination, the vibration suppression effect of the hybrid damping module can be increased. Furthermore, the problem of the attenuation of damping force caused by increasing temperature in a permanent magnet eddy current damping device is addressed.
(FR) Module d'amortissement hybride, dispositif de suppression de vibrations, procédé de suppression de vibrations et ensemble d'éoliennes. Le module d'amortissement comprend une première unité d'amortissement (8). La première unité d'amortissement (8) comprend une partie rotor (8a) et une partie stator (8b) qui est disposée parallèlement à la partie rotor (8a). La partie rotor (8a) est conçue pour pouvoir tourner par rapport à la partie stator (8b) de manière à générer un amortissement électromagnétique. Un passage d'écoulement est formé dans la partie rotor (8a) et/ou la partie stator (8b). Le module d'amortissement hybride comprend une seconde unité d'amortissement (10) comprenant un amortisseur liquide. L'amortisseur liquide communique avec le passage d'écoulement et forme une boucle de circulation. Un liquide (10p) dans l'amortisseur liquide peut s'écouler cycliquement dans la boucle de circulation. Dans le module d'amortissement hybride, une solution combinée de suppression des vibrations qui combine un AMA et un ALA est fournie. Grâce à l'utilisation d'un AMA et d'un ALA en combinaison, l'effet de suppression des vibrations du module d'amortissement hybride peut être augmenté. En outre, le problème de l'atténuation de la force d'amortissement provoquée par l'augmentation de la température dans un dispositif d'amortissement à courant de Foucault à aimant permanent est adressé.
