Abstract
Official abstract text for this publication.
Methods of moving a rotating device of a wind turbine during transportation or standstill are provided. The methods include securing at least one auxiliary device to a position and connecting the device to one or more shafts of the rotating device at transportation or standstill. The auxiliary device is able to store, generate and/or convert energy during transportation, transferring energy continuously from at least one auxiliary device to one or more shafts of the rotating device during transportation or standstill, and moving one or more shafts of the rotating device continuously or discontinuously from a position to another. Also provided is a nacelle for a wind turbine, an auxiliary device, a control system for controlling moving of a rotating device of a wind turbine nacelle during transportation of the nacelle and use thereof.
