Also an azimuth adjustment system for a wind power plant and to a wind power plant. In the disclosed method, the constant residual pressure and/or the constant residual holding torque are/is set as a function of at least one wind speed parameter before commencement of the azimuthal rotation, and the residual pressure and/or the residual holding torque are/is not changed during the azimuthal rotation, in particular during energization of azimuth drive motors.

摘要： Wind farm comprising a farm master and a plurality of wind energy installations. The farm master has a controller with an input for a control parameter for power supplied to a grid and transmits desired value specifications to a local controller of the wind energy installations. The local controller has a dual structure and comprises a desired value channel, to which the desired value specification is applied by the farm master and which is designed to output a stationary reactive power desired value, and a responsive channel comprising an autonomous controller, to which no desired value specification is applied by the farm master and to which an actual voltage of the particular wind energy installation is applied via a washout filter. The autonomous controller with the washout filter enables a fast and dependent response to transient disturbances (e.g., voltage spikes and voltage dips as a result of a short circuit).

摘要： The disclosure relates to checking a rotational speed relay of a wind turbine. The wind turbine comprises a rotational speed sensor for the rotational speed of a shaft. The rotational speed sensor outputs a rotational speed signal, which is fed to a signal input of the rotational speed relay. According to disclosure, the rotational speed signal fed to the rotational speed relay is first inactivated. Then a signal generator is activated, which produces a check signal equivalent to the rotational speed signal. The check signal is fed to the signal input of the rotational speed relay. The signal generator is operated with a check signal that is beyond a rotational speed limit, and a check is performed to determine if the rotational speed relay generates a switch-off command. This allows the functional capability of the rotational speed relay to be checked reliably and at low cost.

摘要： A composite structure for a pile foundation for anchoring a tower structure (e.g., an offshore wind turbine) in ground, which includes a hollow pile introduced into the ground at an erection site of the tower structure and a corner post which is connected to the tower structure and which, on a connection side, is arranged within the pile. The pile and the corner post are fixedly bonded to one another in a bonding region by a cured bonding material. At least one bonding means for transmitting shear forces is fixedly arranged on the pile and/or on the corner post in the bonding region. The bonding means has at least one aperture which is filled with the bonding material or, together with the corner post or pile, forms the aperture that is filled with the bonding material. The aperture encloses the bonding material by an angular range of 90° or more.

摘要： A wind power plant, including a generator driven by a rotor in order to generate electrical power and a controller that includes a pitch module for adjusting a pitch angle of blades of the rotor. The controller has an input for a required power reserve and determines a target pitch angle depending on an operating point of the wind power plant. A secondary pitch controller is also provided, which includes a detector for available power and a dynamic offset module. Input signals for the available reserve power determined by the detector, the required reserve power and the generated electrical power are applied to the dynamic offset module, which is designed to determine a value for a pitch angle offset. An activation element varies the target pitch angle by the pitch angle offset.

摘要： The present invention provides an apparatus for the controlled rotation of a nacelle of a wind turbine, which includes a control device and n of yaw brakes. In standstill operation, the n yaw brakes are actuated to impart a standstill holding moment M1 for holding the nacelle, and the n yaw brakes impart a substantially equal first holding moment. In tracking operation, the n yaw brakes are actuated to impart a tracking holding moment, M2, which is lower than the standstill holding moment M1 (M1>M2). The control device, in tracking operation, actuates a number m of the n yaw brakes to generate substantially the same constant holding moment M3, where M1/n>M3>M2/n, and where the other (n−m) yaw brakes are actuated to generate substantially the same constant holding moment M4, where m*M3+(n−m)*M4˜=M2, and M1/n>M2/n>M4.
