摘要： An assembly and method are provided for preventing exposure of personnel to an opening defined by a surface of a wind turbine. Accordingly, a hatch assembly is arranged adjacent to the opening. The hatch assembly includes a frame structure and a support structure. The frame structure includes a plurality of frame members arranged together to at least partially surrounded opening the plurality of frame members further define a passageway for receiving the support surface. The support surface is slidable between a first position and a second position. The support surface occludes the opening defined by the surface of the wind turbine when the support surface is in the first position and occludes the passageway defined by the plurality frame members when in the second position so as to prevent exposure of personnel to the opening.

摘要： A tower for a wind turbine is disclosed, said wind turbine comprises the tower, a nacelle and a rotor having at least one rotor blade. The tower is configured for supporting the nacelle and the rotor on a support system. The tower itself may be structured as having an upper top end for supporting the nacelle and a lower support end for being placed on the support system. Electric energy generated is transported via power cables from the nacelle to an electric grid, preferably via power electronic components, switches and/or transformers. Furthermore, the nacelle may rotate around the yaw axis according to the current wind direction. Hence, the rotation of the nacelle introduces a twist into the power cables, wherein said twist causes a deviation (shortening) in the length of the power cables. Furthermore, the tower comprises at least one radial cable guiding device for receiving the cable and a cable support arrangement for supporting the cable in a beneficial manner. Additionally, the tower comprises anti-torsion fixation means configured for reducing and/or preventing a propagation of a cable twist of the cables of a hanging portion into power cables of a loop portion. The power cables comprise a hanging portion having a cable axis, a cable loop portion having a horizontal cable loop, and the supported portion being at least partially supported by the cable support arrangement.

摘要： A method for damping an oscillation of a tower of a wind turbine is disclosed, wherein a pitch angle of each of the one or more rotor blades is individually adjustable, the method comprising damping the oscillation of the tower by pitching each rotor blade individually according to tower damping pitch control signals, wherein each tower damping pitch control signal comprises a first periodic component, where a first frequency of the first periodic component corresponds to a frequency difference between a tower frequency of the oscillation of the tower and a rotor frequency of a rotation of the rotor, and where a second periodic component has been reduced or removed. A second frequency of the second periodic component corresponds to a frequency sum of the tower frequency and the rotor frequency.

摘要： An electric power transmission carrier and a manufacturing method of the electric power transmission carrier and an enclosure are provided. The electric power transmission carrier includes an enclosure and an electric power transmission cable mounted on the enclosure. The electric power transmission cable is in direct or indirect surface contact with an inner wall of the enclosure, and the enclosure functions as a heat sink of the electric power transmission cable. In the present application, the electric power transmission cable or the conductor is mounted on the enclosure such as a tower barrel or a high tower, to perform electric power transmission and take the enclosure as a heat sink. The electric power transmission component takes the enclosure, the “heat sink” having a huge thermal capacity, as a “cold source”.
