Title (DE) WINDKRAFTANLAGENBLATTVERSTELLSYSTEM
(EN) WIND TURBINE BLADE ADJUSTMENT SYSTEM
(FR) SYSTÈME D'AJUSTEMENT DE PALE D'ÉOLIENNE
Abstract:
(DE) Die Erfindung betrifft ein Windkraftanlagenblattverstellsystem (300; 300`; 300``; 300```; 300````) für eine Windkraftanlage, aufweisend: -wenigstens einen mittels eines Wechselrichters (41, 42, 43, 401, 402, 403) ansteuerbaren Elektromotor (51, 52, 53); wobei -der Wechselrichter (41, 42, 43, 401, 402, 403) mittels eines Gleichrichters (20) ansteuerbar ist; und wobei -der Gleichrichter (20) und der Wechselrichter (41, 42, 43, 401, 402, 403) im Windkraftanlagenblattverstellsystem (300; 300`; 300``; 300```; 300````) örtlich voneinander getrennt angeordnet sind.
(EN) The invention relates to a wind turbine blade adjustment system (300; 300'; 300''; 300'''; 300'''') for a wind turbine, comprising at least one electric motor (51, 52, 53), which can be controlled by means of an inverter (41, 42, 43, 401, 402, 403), wherein the inverter (41, 42, 43, 401, 402, 403) can be controlled by means of a rectifier (20) and the rectifier (20) and the inverter (41, 42, 43, 401, 402, 403) are spatially separated from each other in the wind turbine blade adjustment system (300; 300'; 300''; 300'''; 300'''').
(FR) L'invention concerne un système d'ajustement de pale (300 ; 300' ; 300'' ; 300''' ; 300'''') d'éolienne pour une éolienne, qui comporte : au moins un moteur électrique (51, 52, 53) pouvant être piloté au moyen d'un onduleur (41, 42, 43, 401, 402, 403). L'onduleur (41, 42, 43, 401, 402, 403) peut être piloté par un redresseur (20). Le redresseur (20) et l'onduleur (41, 42, 43, 401, 402, 403) sont disposés séparément spatialement l'un de l'autre dans le système d'ajustement de pale (300 ; 300' ; 300'' ; 300''' ; 300'''') d'éolienne.
