30 Jun 2010TL;DR: In this paper, a wind turbine with a tower and a nacelle mounted on top of a tower is shown to be capable of yaw motion, and a bearing is attached to the tower for yaw control.
Abstract: The invention relates to a wind turbine comprising a tower (1) and a nacelle (102) mounted on top of the tower (1), the turbine further comprising a bearing (3, 4) for a yaw motion of the nacelle (102) in relation to the tower (1), and a drive assembly (5, 6) for said yaw motion, in turn comprising at least one power unit (5) fixedly connected to the nacelle (102), the power unit (5) comprising a motor (51) and a wheel (52) adapted to be driven by the motor (51) and in engagement with a ring (6) fixedly connected to the tower (1) for effecting the yaw motion, wherein a region of engagement of the ring (6) with the wheel (52) is located separated from the bearing (3, 4). The motor (51) is located below the wheel (52). The bearing (3, 4) is a friction bearing comprising an insert portion (3) fixedly connected to the nacelle (102), and a clamp portion (4) fixedly connected to the tower (1) and in clamping engagement with the insert portion (3).

29 Apr 2011TL;DR: In this article, the authors describe a crane capable of handling major components during installation or servicing of wind turbines, which comprises a main body (4) on which is mounted a crane arm (6), and a lifting point (20) at or near an upper end of the main body, to which a hoisting cable assembly (30) is joined or around which a lifting cable is passed.
Abstract: A crane capable of handling of major components during installation or servicing of wind turbines, comprises a main body (4) on which is mounted a crane arm (6), and a lifting point (20) at or near an upper end of the main body (4) to which a hoisting cable assembly (30) is joined or around which a lifting cable is passed and which carries a major part of the crane weight as it is hoisted up a tower of the wind turbine, wherein the lifting point is laterally adjustable relative to the main body (4) in a direction which is generally towards or away from the tower when in its lifting orientation in order to allow control of the crane balance.

TL;DR: In this article, the preset invention relates to wind turbines and, in particular, inclining a wind turbine from the vertical position, in order to reduce the loads on the tower.
Abstract: The preset invention relates to wind turbines and, in particular inclining a wind turbine from the vertical position. A tower (102) of a wind turbine may be inclined from the vertical position in order to reduce the loads on the tower (102).

TL;DR: In this article, one or more wind speed measurements upstream of a wind turbine are received and a determination of an indication of a current wind speed at the wind turbine is made, the indication may include below rated wind speeds or above rated wind speed.
Abstract: The present invention relates to methods, controllers, wind turbines and computer program products for controlling a wind turbine. One or more wind speed measurements upstream of a wind turbine are received 202 and a determination of an indication of a current wind speed at the wind turbine is made 204. The indication may include below rated wind speed or above rated wind speed. It is determined 205 if the wind speed is in an up transition region or a down transition region based on the received one or more wind speed measurements and the indication of said current wind speed. If determined that said wind speed is in an up transition region or a down transition region then a boost action is performed 206.

28 Sep 2012TL;DR: In this paper, a method for damping grid oscillations is proposed, where a plurality of wind turbine generators are controlled so that each generator can only generate a part of the anti-phase power signal, but all of the generators in combination can generate the entire signal.
Abstract: The invention relates to a method for damping grid oscillations. The oscillations may be damped by controlling e.g. wind turbine generators to inject power to the grid in anti-phase with the grid oscillations. Instead of controlling one or more wind turbine generators to generate the same anti-phase power signal, a plurality of wind turbine generators are controlled so that each of them only generates a part of the anti-phase power signal, but so that all of the wind turbine generators in combination generates the entire anti-phase power signal.
