摘要： A system for transporting and testing a crane includes a crane, a transporting frame and a foundation. A first connecting mechanism is provided for establishing a releasable connection between the crane and the transporting frame. A second connecting mechanism is provided for establishing a releasable connection between the transporting frame and the foundation. In a starting state, the crane, the transporting frame and the foundation are separate from one another. In a transporting state, the crane is connected to the transporting frame. In a testing state, the crane is connected to the transporting frame and the transporting frame is connected to the foundation. The invention also relates to a corresponding method. The invention makes it possible for the crane to be assembled, and tested, at a site remote from an offshore wind turbine.

摘要： A method for operating a wind turbine (10). The wind turbine (10) is operated with variable rotational speed between predeterminable minimum and maximum rotational speeds. A characteristic variable (51) of an oscillation of the wind turbine (10) is detected. The wind turbine (10) includes a tower (14) and a rotor (13). An open-loop or closed-loop control device (36, 50) provides open-loop control or closed-loop control of the rotational speed of the rotor (13) between a minimum rotational speed and a maximum rotational speed during a power-supplying operation of the wind turbine. A sensor (40) detects a characteristic variable (51) of an oscillation of the wind turbine (10) and the minimum rotational speed is changed depending on the characteristic value (51) of the oscillation. The minimum rotational speed is altered depending on the characteristic variable (51) of the oscillation by the open-loop or closed-loop control device (36, 50).

摘要： The invention relates to a mobile rotary drive for a wind rotor of a wind power plant having a frame comprising a drive wheel for driving a segment of a rotor shaft of the wind power plant and a drive set which drives the drive wheel in rotation as a drive pinion, wherein the drive wheel is a friction wheel and interacts with a pressing device in such a way that the pressing device generates a force which presses the friction wheel onto the segment with the result that the friction wheel can apply a drive torque to the segment through friction, wherein a torque support for supporting an opposing torque to the drive torque generated by the friction wheel is also provided. Thanks to the friction wheel drive, there is no need for specific pre-equipping of the wind power plant. The invention makes available a mobile rotary drive which can be transported from one wind power plant to another.

摘要： Wind farm comprising a farm master (1) and a plurality of wind energy installations (4). The farm master (1) has a controller (15) with an input for a control parameter for power supplied to a grid and transmits desired value specifications to a local controller (5) of the wind energy installations (4). According to the invention, the local controller (5) has dual structure and comprises a desired value channel (6), to which the desired value specification is applied by the farm master (1) and which is designed to output a stationary reactive power desired value, and a responsive channel (7) comprising an autonomous controller (75), to which no desired value specification is applied by the farm master (1) and to which an actual voltage of the particular wind energy installation (4) is applied via a washout filter (71). The autonomous controller (75) with the washout filter (71) enables a fast and dependent response to transient disturbances, in particular voltage spikes and voltage dips as a result of a short circuit. The individual wind energy installation and the wind farm as a whole therefore gain a behaviour which is identical to a synchronous generator and is very favourable for grid stability in the event of voltage disturbances.
