(FR) COMMANDE DE LA PROFONDEUR DE FONCTIONNEMENT D'UN DISPOSITIF
Abstract
(EN)
A method is described of controlling a tethered, underwater, water current-driven turbine, power-generating device. A predetermined maximum depth and a predetermined minimum depth are set. In response to sensing depth of the device, an ascend protocol or a descend protocol is selectively invoked. These protocols maintain an operating depth of the device that is midway between the predetermined maximum depth and the predetermined minimum depth. The turbine includes variable-pitch rotor blades. A maximum allowable drag force load on the turbine rotors is selected. The pitch of the variable-pitch rotor blades on the turbine is adjusted such that the drag force loading of the device does not exceed a maximum design level.

La présente invention concerne la commande d'une génératrice d'énergie immergée ancrée comportant une turbine entraînée par le courant d'eau. On définit une profondeur maximale et une profondeur minimale. En réaction à la profondeur détectée du dispositif, on appelle sélectivement un protocole de montée ou un protocole de descente qui conservent le dispositif à une profondeur de fonctionnement à mi-chemin entre la profondeur maximale et la profondeur minimale. Les pales équipant le rotor de la turbine étant à pas variable, on définit une charge de traînée maximum admise devant s'exercer sur les rotors de la turbine, et on règle le pas des pales pour une charge de traînée du dispositif n'excédant pas un niveau maximum calculé.
