The invention relates to a method for operating an arrangement for feeding electrical power from a wind energy installation (2) into an AC voltage system (5) via an energy transmission path (8), which is limited firstly by an installation-side transformer (6) and secondly by a system-side transformer (7) with a power factor correction device (10) connected, at a common coupling point (4) between the energy transmission path (8) and the AC voltage system (5) using a regulation device (9), which controls the wind energy installation (2) and to which, on the input side, a variable (M1) which is proportional to the reactive power on the energy transmission path and a further measured variable are applied. In order to be able to implement such a method inexpensively, according to the invention a measurement signal (M3) produced at the output (30) of the power factor correction device (10) is used as further measured variable. The regulation device used is a regulation device (9) having such a regulation characteristic (K2) that the voltage (U) on the low-voltage side of the system-side transformer (7) increases, depending on the reactive power (Q1) on the energy transmission path (8), from the inductive range (ind) to the capacitive range (cap). The invention also relates to an arrangement for feeding electrical power from a wind energy installation into an AC voltage system. |
