The invention relates to a wind power station (1) for energy generation with an axial-flow, rotating, vortex-generating wind concentrator (2) pivot-mounted on a shaft (3), covered by a ring-shaped outer jacket (4) which on its outside features flow channels distributed over 360° and which is equipped concentrator blades (7) in a circular arrangement between the shaft (3) and the ring-shaped outer jacket (4). To create favorable conditions, it is proposed to include sawtooth-shaped, curved edge-vortex-generating guide profiles (5) producing a downstream vortex coil across the entire cross-section of the ring-shaped outer jacket (4).
