Title:
WIND FARM AND METHOD FOR OPERATING A WIND FARM
Document Type and Number:
WIPO Patent Application WO/2012/089675
Kind Code:
A3
Abstract:
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).
