Problems solved by technology

This causes inconvenience to the available space on the vessel and may have to use a larger vessel than would be required to perform the replacement at engine room level directly on top of the tower
Furthermore, due to the weight of the nacelle together with the generator, more lifting operations must be provided offshore, and besides the loss of production of the turbines, this also means additional time and costs for the charter of the vessel

Embodiment Construction

[0038] figure 1 A wind turbine 1 is shown comprising a tower 2 mounted on a non-depicted foundation. The nacelle 3 is arranged on top of the tower 2 .

[0039] The wind turbine 1 may be an inland or offshore wind turbine.

[0040] The wind turbine 1 also comprises a wind rotor 5 having a rotor hub 6 and two, three or more blades 4 (in figure 1 Only two blades are visible in the perspective view of 4). The wind rotor 5 is rotatable about a longitudinal axis Y of rotation. The blades 4 extend radially relative to the axis Y of rotation.

[0041] The wind turbine 1 comprises a permanent magnet generator 11 .

[0042] The wind rotor 5 is rotationally coupled with a permanent magnet generator 11 either directly or by means of a rotatable main shaft 9 and through a gearbox (not shown). A schematically depicted bearing assembly 8 is provided to hold the main shaft 9 and rotor 5 in position. The rotatable main shaft 9 extends along an axis of rotation Y.

[0043] The permanent...

Abstract

The invention relates to a gyro for stabilizing wind turbine movements. The wind turbine (1) comprises:- a tower (2) extending axially along a longitudinal axis (Z),- a nacelle (3) and a rotor (5) attached to an upper end of the tower (2),- a gyroscope (40),- a controller device (50) for operating the gyroscope (40) for stabilizing a movement and / or an oscillation of the wind turbine (1) with respect to a spatial reference system (60).

Description

[0001] describe [0002] Stabilize the wind turbine. technical field [0003] The invention relates to a wind turbine equipped with a device for stabilizing an inoperative wind turbine, in particular during installation or maintenance. The invention also relates to a method of stabilizing an inoperative wind turbine during installation or maintenance, in particular during installation or replacement of components of the wind turbine. Background technique [0004] During maintenance operations on a wind turbine, in particular an offshore wind turbine, dynamic elements cause the wind turbine to move, thus hindering the performance of the operation or greatly delaying the task. [0005] Wind, waves and tides are factors that cause the turbine to move in a circular motion and thus pose a danger to the technicians involved. Such a circular motion may be eg a rotation of the nacelle about a yaw axis or an oscillation of the entire turbine about a vertical or horizontal axis. ...
