    • A blade gripping device for gripping a rotor blade of a wind turbine is provided. The device comprises a first frame which is essentially horizontally aligned in a designated operating position and a second frame which is essentially horizontally aligned in the designated operating position and a blade gripping assembly with a number of blade gripping tools. Thereby, the first frame and the second frame are connected to each other via a swivel or other similar type connection, the connection realized to permit a yawing movement of the second frame relative to the first frame. The first frame comprises a rectangular carrying structure with at least four connectors for connection to a lifting device, which connectors are positioned essentially at the corners of the rectangular structure. Further, the invention concerns a method of operating a blade gripping device for gripping a rotor blade of a wind turbine.
    • 提供了一种用于夹持风力涡轮机的转子叶片的叶片夹持装置。 该装置包括基本上在指定的操作位置水平对准的第一框架和在指定操作位置基本上水平对准的第二框架和具有多个叶片夹紧工具的叶片夹持组件。 由此,第一框架和第二框架通过旋转或其它类似的连接彼此连接,该连接被实现为允许第二框架相对于第一框架的偏转运动。 第一框架包括具有至少四个用于连接到提升装置的连接器的矩形承载结构,该连接器基本上位于矩形结构的拐角处。 此外,本发明涉及一种操作用于夹紧风力涡轮机的转子叶片的叶片夹紧装置的方法。

    • A power supply arrangement adapted to provide auxiliary power to a wind farm that feeds into a HVDC transmission link is provided. The power supply arrangement has an auxiliary power supply to deliver auxiliary power (Paux) to the wind farm; a backfeed control for initiating provision of a backfeed voltage on the HVDC link during a wind farm downtime; a backfeed switch to close a DC current path between the HVDC link and the auxiliary power supply; and a power converter for converting the backfeed voltage into auxiliary power (Paux). A wind farm arranged to feed into a HVDC transmission link is also provided, having such a power supply arrangement for providing auxiliary power (Paux) to the wind farm during a wind farm downtime. A method of providing auxiliary power (Pbackfeed) to a wind farm during a wind farm downtime is also provided.
