Abstract

L'invention concerne un système équipé d'une série de turbines (1) reliées entre elles par un engrenage définissant une couronne (4) située dans la partie périphérique de chacune des turbines (1), celles-ci étant toutes montées entre les tirants (10) d'une structure commune (8) par rapport à laquelle tout l'ensemble peut basculer afin de limiter la puissance du système indépendamment de l'intensité du vent. La transmission de rotation de l'ensemble des turbines (1) peut se concentrer sur un seul générateur (7) ou bien les turbines peuvent former des groupes, chacun d'eux ou plusieurs à la fois pouvant agir sur un ou plusieurs générateurs, l'ensemble comprenant également des écrans déflecteurs (12) servant à orienter le vent de manière appropriée afin d'obtenir un rendement maximal du système. Les turbines peuvent être indépendantes mécaniquement, et peuvent être chacune pourvue d'un générateur connecté électriquement aux autres générateurs.
