FLOATING OFFSHORE WIND POWER PLANT HAVING A VERTICAL ROTOR AND MODULAR WIND FARM COMPRISING A PLURALITY OF SUCH WIND POWER PLANTS

摘要

The invention relates to an offshore wind power plant (10) that floats on the surface of the water (32), comprising a rotor (12) with a shaft (16) that can rotate about a vertical axis of rotation (14), wherein the shaft (16) is connected to a generator (18), which converts a rotational movement of the shaft (16) into electrical energy, and comprising at least one float (30). To design and develop the wind power plant (10) so as to optimise use thereof offshore, in particular with regard to increased availability and improved efficiency (overall costs for producing, erecting and operating the wind power plant (10) in relation to the amount of energy generated), the generator (18) is arranged in the float (30) and can be accessed from above the surface of the water (32) via a service hatch (34) in the float (30). The generator (18) is preferably a large ring generator that lies flat in the float (30) and is driven directly by the rotor (12).
