Abstract

The invention relates to a wind-power unit having a kite (1 ) having a line (3), which is connected with a generator (2) in a ground station. Control means (4, 7) are arranged to set the position of the kite (1 ) in relation to the wind (W). By coupling means (5), the generator is (2) connected with an electric mains (6). According to the invention, the coupling means (5) comprises an electrical energy converter connected with the stator of the generator (2). The invention also relates to a method for generating electrical energy, where the tensile force from a kite is utilized to drive a generator. The current from the generator is converted and is delivered to the mains.
