Abstract (en)

[origin: WO2020144169A1] The invention relates to a wind turbine (1) comprising a converter (7) connected to a generator (4), which converter supplies at least some of the energy generated by the electrical generator (4) into an electrical grid (10), sensors (31, 32) for interference in the electrical grid (10) and a controller module (20) for controlling the converter (7) and/or the wind turbine (1). The controller module (20) comprises a grid interference module (25) which, in the case of detected interference in the electrical grid (10), counteracts the interference. According to the invention, the controller module (20) comprises an override module (26) which, in the case of a detected interference in the grid (10), is provided in order to deactivate the grid interference module (25) at least in part. The invention thus improves the behavior in interference situations in that it detects, over the course of the interference, that at least parts of the inherent grid stabilization functions do not counteract the interference and, in this specific situation, it deactivates the respective harmful grid stabilization functions. The invention further relates to a corresponding method.
