Method of moving the rotating means of a wind turbine during transportation or stand still, method of controlling the moving of the rotating means, nacelle, auxiliary device, control and monitoring system and use hereof

A method for transporting or storing a rotating device of a wind turbine nacelle, the method comprising the steps of:

• providing an auxiliary device in a fixed position in relation to the rotating device, the rotating device including a high speed shaft at a gearbox and a generator shaft at a generator configured to be coupled to the gearbox;
• connecting the auxiliary device to the high speed shaft and separately connecting the auxiliary device to the generator shaft using a connector;
• activating the auxiliary device to directly transfer force to each of the high speed shaft and the generator shaft, to thereby move the high speed shaft and the generator shaft during transportation or standstill;
• and
• supplying oil lubrication to the rotating device using a pump driven by a power supply the power supply activating the pump to supply oil lubrication during the movement of the high speed shaft and the generator shaft of the rotating device of the wind turbine nacelle,
• wherein the movement of the high speed shaft and the generator shaft reduces detrimental effects to the rotating device during transportation or standstill.
