Title (EN) BEARING PROTECTION ARRANGEMENT
(FR) AGENCEMENT DE PROTECTION DE PALIER
Abstract:
(EN) The invention describes a bearing protection arrangement (10, 1) of a journal bearing (22L, 22F) arranged between a housing (21) and a rotary component (20) of a wind turbine (2), which bearing protection arrangement (10, 11) comprises a wind speed monitor (10) arranged to monitor wind speed (S) in the vicinity of the wind turbine (2) and to generate a wake-up signal (W) when the wind speed (S) exceeds a predefined minimum (Smin); a mode switch module (11) of a backup battery (24) arranged to provide restart power to an auxiliary (23) of the wind turbine (2), which mode switch module (11) is adapted to switch the backup battery (24) from a normal-power mode (M1) into a low-power mode (M0) to conserve sufficient restart power after low wind-speed conditions, and to switch the backup battery (24) from the low-power mode (M0) into a normal-power mode (M1) in response to the wake-up signal (W). The invention further describes a wind turbine (2); and a method of protecting a journal bearing (22L, 22F) of a wind turbine (2) during standstill.
(FR) L'invention concerne un agencement de protection de palier (10, 1) d'un palier lisse (22L, 22F) disposé entre un boîtier (21) et un composant rotatif (20) d'une éolienne (2), lequel agencement de protection de palier (10, 11) comprend un dispositif de surveillance de vitesse du vent (10) agencé pour surveiller la vitesse du vent (S) au voisinage de l'éolienne (2) et pour générer un signal d'alarme (W) lorsque la vitesse du vent (S) dépasse un minimum prédéfini (Smin); un module de commutation de mode (11) d'une batterie de secours (24) agencée pour fournir une puissance de redémarrage à un auxiliaire (23) de l'éolienne (2), lequel module de commutation de mode (11) est conçu pour commuter la batterie de secours (24) d'un mode de puissance normale (M1) en un mode basse puissance (M0) pour conserver une puissance de redémarrage suffisante après des conditions de faible vitesse du vent, et pour commuter la batterie de secours (24) du mode basse puissance (M0) au mode de puissance normale (M1) en réponse au signal d'alarme (W). L'invention concerne en outre une éolienne (2); et un procédé de protection d'un palier lisse (22L, 22F) d'une éolienne pendant l'arrêt.
