摘要

A nacelle stand and a method for building and testing a nacelle for a wind turbine using a nacelle stand, the nacelle stand being suitable for supporting a nacelle for a wind turbine, during manufacturing and assembly of the nacelle, testing and transport. The nacelle stand has a connecting arrangement for rigid connection to a yaw system arranged at the main frame of the nacelle, a midsection, a horizontal bedplate and a center part with a number of fingers extending away from the center part in a horizontal plane, the fingers each having an angle larger than 0 degrees and less than 90 degrees relative to a longitudinal axis of the stand.

主权项

1. A nacelle stand suitable for supporting a nacelle for a wind turbine during manufacturing and assembly of the nacelle, and during transport, the nacelle comprising a main frame suitable for installation of a number of components, a main shaft, a hub comprising a number of blades and a yaw system, the nacelle stand comprising a first longitudinal axis and a traverse axis, connecting means arranged for rigid connection to the yaw system, said yaw system being arranged at the main frame, the nacelle further comprising a nacelle cover extending over said main frame and over components installed on the main frame, the nacelle stand further comprising, at least a midsection having a vertical centerline, the midsection being arranged between the connecting means and a bedplate, the bedplate extending in a first horizontal plane and comprising a center part and a plurality of fingers extending away from the center part in the first horizontal plane, the fingers each having an angle larger than 0 degrees and less than 90 degrees relative to said longitudinal axis.
