Title: WIND POWER PLANT COMPRISING A STEERABLE KITE
Abstract:
The invention relates to a device for converting wind energy to mechanical energy. Said device comprises a wind-impacted element connected to a base station via a traction rope, a traction rope reservoir, arranged on the base station and adapted to receive a section of the traction rope, a control device adapted to cyclically veer the traction rope from the traction rope reservoir and haul it, an energy converter, adapted to convert energy from the wind power transmitted by the wind-impacted element via the traction rope and the movement of the section of the traction rope veered from the traction rope reservoir to an electrical, thermodynamical or mechanical form of energy, a steering device adapted to generate a steering movement by a first axis or in a first direction of the wind-impacted element relative to the air current, a control unit adapted to bring, by means of the steering device, the wind-impacted element into a flying position with low rope traction after veering of the section of the traction rope and for bringing the section of the traction rope into a flying position with high rope traction once the section of the traction rope is hauled. The invention is characterized in that the wind-impacted element has an aerodynamic profile which generates, when wind impacts it in a direction perpendicular to the traction rope, a lift in the direction of the traction rope. The steering device is adapted to generate a steering movement of the wind-impacted element relative to the air current in a second direction or by a second axis that is different from the first direction or axis. The control unit is adapted to displace the wind-impacted element on a predetermined trajectory in a plane of travel perpendicular to the traction rope. ©KIPO&WIPO 2009
