Title (EN) HYDRAULIC TRANSMISSION METHODS AND APPARATUS FOR WIND TURBINES
(FR) PROCÉDÉS ET APPAREILS DE TRANSMISSION HYDRAULIQUE POUR ÉOLIENNES
Abstract: front page image
(EN)A hydraulic transmission for a wind turbine that includes a rotor, one or more blades mounted to the rotor, a hydraulic pump mechanically connected to the rotor, and a hydraulic motor. The hydraulic pump and the hydraulic motor are connected to one another by a high pressure circuit. The hydraulic pump maybe a variable displacement hydraulic pump and the hydraulic motor may include a variable displacement hydraulic motor. The wind turbine, including the rotor, the blades of the rotor, the hydraulic pump, and the hydraulic motor may be controlled according to different approaches.
(FR)La présente invention se rapporte à une transmission hydraulique destinée à une éolienne qui comprend un rotor, une ou plusieurs pales montées sur le rotor, une pompe hydraulique mécaniquement reliée au rotor, et un moteur hydraulique. La pompe hydraulique et le moteur hydraulique sont reliés l'un à l'autre par un circuit haute-pression. La pompe hydraulique peut être une pompe hydraulique à déplacement variable et le moteur hydraulique peut comprendre un moteur hydraulique à déplacement variable. L'éolienne, comprenant le rotor, les pales du rotor, la pompe hydraulique et le moteur hydraulique, peut être commandée selon différentes approches.
