Abstract: The invention relates to a wind turbine having a rotor (12), a generator (14) driven by the rotor, a converter (15), and a control device (167), which has an input for a control signal for reactive power output and a controller (72) for the converter (15). The controller (72) determines a reactive power target value for the wind turbine and corrects the output reactive power in dependence on the voltage present at the wind turbine. The invention provides for an additional module (8) for the controller (72), which additional module has separate small and large signal paths (81, 82) and interacts with the controller (72) in such a way that the small signal path (81) has an additional storage element (83) in comparison with the large signal path (82), which additional storage element stores state values of the small signal path (81) 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 tubular tower (11), of a wind energy plant (10) with a current conduction means system (25, 35) for transmitting electrical power from a generator on the tower (11), to a power module at the base of the tower. The current conduction means system (25, 35) has three electrical conductors (27.1, 27.2, 27.3; 37.1, 37.2, 37.3; 45.1, 45.2, 45.3) arranged next to one another. A housing (26, 36, 46) is connected to the inner tower wall at predetermined distances using connecting devices which have electrical cross-sections conducting with the tower wall. The distances between the connecting devices in the longitudinal extent of the tower (11) and the cross-sections of the connecting devices between the housing (26, 36, 46) and the tower wall are dimensioned such that during a fault, the voltage drop between the tower wall and the housing (26, 36, 46) does not exceed a predetermined touch voltage.

Abstract: A method for determining an energy yield loss of a first wind turbine of a wind farm that includes a plurality of wind turbines. The first wind turbine is operated in a reduced energy yield mode that is outside an energy-optimized normal operating mode and a reduced energy yield of the first wind turbine is determined. At least one second wind turbine is selected according to a pre-determinable criterion. The energy yield of the at least one second wind turbine is determined and depending upon the energy yield of the at least one second wind turbine, an energy yield potential of the first wind turbine is determined. The difference between the energy yield potential of the first wind turbine and the determined reduced energy yield is formed.

Abstract: 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.
