    Abstract: In the method according to the invention for communicating between installations, which are organized in an order according to a sortable feature, for example installation numbers, in a wind farm, in which information transmitted by an installation in the form of a message is received by all other installations in the wind farm, a cyclically recurring, temporal transmission interval is set up. A point in time in the transmission interval at which the installation can transmit a message is assigned to each installation on the basis of the position thereof in the order, wherein points in time are organized from the start of the transmission interval, starting from the installation number at the first position in the order, in accordance with the position in the order. The start of the transmission interval is synchronized in all installations using a message from the installation at the first position in the order.

    Abstract: A wind turbine having a rotor, a generator driven by the rotor, a converter, a control device having an input for a control signal for reactive power output and a controller for the converter, the controller determining a reactive power target value for the wind turbine and correcting the output reactive power in dependence on the voltage present at the wind turbine, and an additional module for the controller having separate small and large signal paths and interacting with the controller such that the small signal path has an additional storage element in comparison with the large signal path, which additional storage element stores state values of the small signal path for the past. Thus, small voltage changes can be reacted to more slowly and while taking into account past values, whereas large changes can be reacted to quickly, in particular in the event of a network short circuit.

    Abstract: 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.
