摘要： The invention relates to a method for operating a wind farm, and also to a wind farm (1) in which the power generated by the wind energy installations (10) is fed to a power supply system (40) via a system (20) that is internal to the wind farm and via a substation (30). The invention provides for the farm director (50) of the wind farm (1) to ascertain a standard target voltage value (Utarget) and to transmit it to the control units (17) of the individual wind energy installations (10) on the wind farm. The control units (17) can use an overall factor (Ib) to regulate the reactive power generated by a wind energy installation (10). The overall factor (Ib) can be calculated from the difference between the actual voltage (Uactual) across the wind energy installation and the target voltage value (Utarget), multiplied by a gain factor (kIb). On account of the impedance in the internal system (20) of the wind farm (1), the wind energy installations (10) which are situated far away from the substation (30) thus generate less reactive power than the wind energy installations (10) which are situated close to the substation (30).

摘要： 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.

摘要： The invention relates to a method for operating a wind farm and to a wind farm. When a wind farm (1) and the wind energy installations (10) involve target values for the reactive power being prescribed by a farm regulatory device (50), the invention provides for said target values for the reactive power to be ignored by the control units (17) when controlling the respective wind energy installation (10) in the event of a power supply system fault in the power supply system (40). Only when the power supply system fault has been rectified are said target values considered by the control units (17) again for controlling the respective wind energy installation (10).

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 a 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.
