摘要： 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 (5) and/or a force transducing disc which is mounted or can be mounted on a shaft (1) of the drive train which is switched downstream from the rotor, which is structured for engagement of a force transmitting means (4), 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 (3) for transmitting the drive force to the force transducer wheel (5) and/or the force transducing disc.

摘要： The invention relates to a method for operating a wind turbine (10) comprising a rotor (12) and a generator (18), connected to said rotor (12), for emitting electrical power to an electrical grid, said rotor (12) comprising rotor blades (14) whose blade pitch angles (α) can be moved during operation in order to control the rotational speed (n) of the rotor (12). Upon reaching a rotational speed (n) higher than a rotational speed limit (n
lim ) that delimits an operational range (34, 34', 34'') of said wind turbine (10), the rotor (12) is forcibly braked by increasing the blade pitch angle (α) with a predefined positive blade pitch angle movement rate (ω
r ), particularly with a maximum potential positive blade pitch angle movement rate (ω
r, max ). According to the invention, the rotational speed limit (n
lim ) is altered as a function of a blade pitch angle movement rate (ω) set by the control. The invention also relates to a corresponding wind turbine (10).

摘要： In order to provide an attachment element for fastening of attachment parts (P) to a metal inner tower wall (T) of a tower of a wind energy system, comprising a first end side for welding to the inner tower wall (T) and a second end side for fastening an attachment part (P), said second side opposite the first end side, wherein the resultant weld connection between said attachment element and the tower wall is under a reduced stress, thereby enabling the connection point to be assigned to a higher fatigue class, it is proposed that such an attachment part have a total cross-sectional material thickness that is reduced near the first end side in comparison to a total material thickness in a cross-section shifted toward the second end side.

摘要： Disclosed is a housing for the nacelle of a wind turbine, comprising a support structure (15) composed of tubes and braces, preferably made of metal, especially steel, or plastic, especially fiberglass reinforced plastic (FRP), and covering segments (2, 3, 4) which are fastened to said support structure (15). The housing is characterized in that the covering elements (2, 3, 4) have a coating surface made of plastic, especially FRP, and are self-supporting. Such a housing for the nacelle of a wind turbine can be manufactured with little effort from inexpensively produced parts and is easy to assemble. In particular, said housing combines the advantages of previously known structures that are self-supporting as a whole and the paneling of a support structure comprising parts that are not self-supporting without having the disadvantages thereof.
