METHOD AND ARRANGEMENT FOR FEEDING ELECTRICAL POWER FROM A WIND TURBINE INTO AN AC VOLTAGE NETWORK

The invention relates to a method for feeding electrical power from a wind turbine (2; 3) via an energy transmission path (8; 9) into an AC voltage network (11) at a common coupling point (10) between the energy transmission path (8; 9) and the AC voltage network (11), wherein the voltage (Uk) at the coupling point (10) is detected and is supplied to a tapping selection regulator (16; 17). Moreover the voltage (Us) at the output of the wind turbine (2; 3) is detected and supplied to the tapping selection regulator (16; 17). On the basis of the magnitude of the detected voltages (Uk, Us), with a feed transformer (14; 15) disposed on the energy transmission path (8; 9) and provided with tappings, tappings are assigned by the tapping selection regulator (16; 17) in such a way that at the output of the wind turbine (2; 3) a voltage (Us) occurs which leads to a predetermined voltage (Uk) at the common coupling point (10). The invention also relates to an arrangement for feeding electrical power from a wind turbine into an AC voltage network.
