Abstract[English]
Wind turbines (10) and methods of controlling wind turbines (10) including cable supported rotors (22). The cable supported rotor (22) includes a plurality of blades (26) and a plurality of cable assemblies (32) that support the blades (26). A plurality of tension mechanisms (44) controls the amount of tension in each of the cable assemblies (32). At start up, the tension is increased until a tension setpoint is reached, and tension levels are balanced across the plurality of cable assemblies (32). Tension may be readjusted periodically, and may be actively controlled during operation of the wind turbine (10) based on functions of tension versus azimuth, wind speed, rotor or generator speed, and blade pitch angle.[French]
L'invention concerne des éoliennes (10) et des procédés de commande d'éoliennes (10) comprenant des rotors supportés par câble (22). Le rotor supporté par câble (22) comprend une pluralité de pales (26) et une pluralité d'ensembles câbles (32) qui supportent les pales (26). Une pluralité de mécanismes de tension (44) commande la quantité de tension dans chacun des ensembles câbles (32). Au démarrage, la tension est augmentée jusqu'à ce qu'une consigne de tension soit atteinte, et des niveaux de tension sont équilibrés à travers la pluralité d'ensembles câbles (32). La tension peut être réajustée périodiquement, et peut être commandée activement pendant le fonctionnement de l'éolienne (10) sur la base de fonctions de tension selon l'azimut, la vitesse du vent, la vitesse du rotor ou du générateur, et l'angle de pas de pale.
