Abstract: Thus, a method for operating a wind turbine, a wind farm or the like and a power-to-gas unit connected electrically thereto is provided. The wind turbine or the wind farm generates electric power if there is sufficient wind and feeds this power into an electrical grid connected to the wind turbine or to the wind farm. Each wind turbine is operated with a predetermined power curve. Electric power is generated by the wind turbine or the wind farm once a first wind speed (starting wind) has been reached. The wind turbine or the wind farm is in a partial-load operating mode as long as the wind speed is between the first wind speed (starting wind) and a second wind speed (nominal wind). The wind turbine or the wind farm is in a nominal power range when the wind speed is in a range which is greater than the second wind speed (nominal wind speed).
Abstract: The invention concerns a large-size rolling bearing which is in the form of a multi-row ball-bearing rotary joint for carrying axial loads, radial loads and tilting moments. The large-size rolling bearing has an outer race, an inner race, a first ball row and a second ball row. The first ball row and the second ball row are respectively arranged in axially mutually spaced relationship in a four-point bearing configuration, associated with the first ball row are four raceway portions and associated with the second ball row are four raceway portions. The invention concerns in particular a large-size rolling bearing in which a surface of a respective raceway portion provided in the inner race is larger than the surface of the respectively adjacent raceway portion provided in the inner race and equal to the surface of the respectively diametrally oppositely disposed raceway portion provided in the outer race.
Abstract: The present invention concerns a lifting apparatus, in particular a cross lifting beam, for lifting a first pylon segment of a concrete pylon of a wind power installation by means of a crane, including at least one fixing means for fixing the pylon segment to the lifting apparatus, and at least one release apparatus for releasing a connection between the lifting apparatus and the pylon segment.
