Title (EN) METHOD AND SYSTEM FOR HARNESSING WIND ENERGY USING A TETHERED AIRFOIL
(FR) PROCÉDÉ ET SYSTÈME D'EXPLOITATION DE L'ÉNERGIE ÉOLIENNE UTILISANT UNE VOILURE CAPTIVE
Abstract:
(EN) The present disclosure is directed at a method and system for harnessing wind energy using a tethered airfoil. During a traction phase, wind is allowed to extend a kite tether. Wind energy that is harnessed through extension of the kite tether is mechanically stored prior to using the wind energy that is stored to generate electricity. During a retraction phase, the wind energy that is mechanically stored during the traction phase is used to retract the kite tether. Beneficially, the mechanical storage allows the kite tether to be retracted without relying on electricity from an electrical grid.
(FR) La présente invention concerne un procédé et un système d'exploitation de l'énergie éolienne utilisant une voilure captive. Pendant une phase de traction, le vent étend un câble de cerf-volant. L'énergie éolienne captée par l'extension du câble de cerf-volant est mécaniquement stockée. Par la suite, l'énergie éolienne stockée est utilisée pour générer de l'électricité. Pendant une phase de rétraction, l'énergie éolienne mécaniquement stockée pendant la phase de traction est utilisée pour rétracter le câble de cerf-volant. Avantageusement, le stockage mécanique permet de rétracter le câble de cerf-volant sans dépendre d'un réseau de distribution d'énergie électrique.
