Abstract: An apparatus and method for producing a rotor blade spar cap for a rotor blade of a wind turbine. The apparatus includes a mold, which has a cavity-like depression in cross section, in which material for a rotor blade spar cap can be placed, and a sheet-like mold covering for sealing off the depression. The depression has side walls, an opening bounded by the side walls and a base area between the side walls. In accordance with the method, fiber material and/or fiber-reinforced material is placed in the depression of the mold such that the material finishes flush with the side walls with respect to the height of the rotor blade spar cap, the depression is sealed off by the sheet-like mold covering, the material is fused together to form the rotor blade spar cap and the rotor blade spar cap is removed from the mold.

Abstract: 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).
