An adjusting device for adjusting the rotation angle position of the rotor of a wind energy system should be improved by the invention, whereby a complicated processing of the brake disc previously used for engagement of the drive is no longer necessary, and whereby said brake disc can be flexibly arranged in an area with sufficient construction space. For this purpose, the adjusting device has at least one force transducer wheel and/or a force transducing disc which is mounted or can be mounted on a shaft () of the drive train which is switched downstream from the rotor, which is structured for engagement of a force transmitting means, and is designed as an independent component. The device also has a drive means for producing a drive force, and at least one force transmission means for transmitting the drive force to the force transducer wheel and/or the force transducing disc.

A method for operating a wind turbine having at least one blade includes determining an ambient air operating envelope and controlling a power output of the wind turbine at least partially based on the determined ambient air operating envelope. Determining an ambient air operating envelope includes measuring at least one of an ambient air temperature, an ambient air pressure, an ambient air humidity, and wind turbine power output. The method also includes comparing at least one of a measured ambient air temperature, a measured ambient air humidity and a measured ambient air pressure to predetermined ambient air temperature, pressure and humidity values. The method further includes referencing the predetermined ambient air temperature, pressure and humidity values to at least one operational parameter of the wind turbine. The method also includes determining if an existing wind turbine power output is within a range associated with the determined ambient air operating envelope.

What is disclosed is a wind turbine comprising a tower with a closable climbing opening and electrical components disposed inside the tower. In order to provide said wind turbine with the ability to provide a cooling system for cooling the electrical components, in particular the electrical components disposed in the area near the base of the tower, said cooling system able to be cost-effectively installed, it is proposed that the door opening of the wind turbine be located in a continuous tower port which is larger than the door opening, with air intake and exhaust openings passing through said tower port for passage of cooling air.

A ventilation arrangement for a wind turbine includes an air inlet opening located in a nose cone of said wind turbine, a manhole cover for covering a manhole of a rotor hub of said wind turbine, the manhole cover providing a vent opening for venting hot air from an internal space of said rotor hub, and a flexible piping establishing fluid communication between the internal space of the rotor hub and the air inlet opening.

Ventilation arrangement

The modular kit for a tower has a height ranging between a minimum height and a maximum height, in particular for a wind energy turbine, comprises a first conical tower segment () comprising a steel tube having a predetermined length (), a second conical tower segment () comprising a steel tube having a predetermined length (), and a first cylindrical tower segment () comprising a steel tube having a length between a predetermined minimum length and a predetermined maximum length. The length of the first cylindrical tower segment () can be adapted to the necessary height of the tower between its minimum height and its maximum height. The minimum height is the sum of the predetermined lengths () of the first and second conical tower segments () and the minimum length of the first cylindrical tower segment (). The maximum height is the sum of the predetermined lengths () of the first and second conical tower segments () and the maximum length of the first cylindrical tower segment ().

A method facilitates lubrication of components. The method includes coupling a blade to a pitch control mechanism such that a bearing is positioned between the blade and the pitch control mechanism. The method further includes coupling a control system to the pitch control mechanism and configuring the control system to control the blade pitch mechanism for controlling movement of the blade and rotate the blade from a first position to a second position when a predetermined amount of time has elapsed.

The hydraulic brake system comprises a piston/cylinder unit () for activating and releasing a brake (), comprising a volume () adapted to have a pressurized working fluid supplied thereto for moving the piston () from a braking position into a release position for releasing the brake. Further, the hydraulic brake system comprises a supply line () for the supply of working fluid from a reservoir (), a discharge line () for the discharge of working fluid from the volume () of the piston/ cyliinder unit (), a first valve () and an element () for determining the flow resistance, a bypass line () provided with a second ON/OFF valve () and arranged for a flow in parallel to the discharge line (). At the start of a braking process, among the two ON/OFF valves () which in the released condition of the brake are in the closed condition, the first ON/OFF valve () is opened and, upon lapse of a presettable first time period (T) from the opening of the first ON/OFF valve (), the second ON/OFF valve () is opened.

A method for controlling a rotational speed of a rotor having at least one rotor blade, a rotor shaft, and an electrical generator coupled thereto. The method includes controlling a torque of the rotor shaft by controlling a torque of the electrical generator, alternating between changing an angle of pitch of the at least one rotor blade and maintaining the angle of pitch of the at least one rotor blade substantially constant, and maintaining a substantially constant rotational speed of the rotor during variable wind speeds above a predetermined rated wind speed.
