Abstract
A method for controlling a wind turbine which is connected to an electrical grid, detects a grid frequency present in the grid and in the case of which the power output is regulated on the basis of the grid frequency by a controller and, in particular, switches off the power feed into the electrical grid if a limit value of a grid frequency is exceeded, wherein a change in the grid frequency over time is detected, a rate of change is determined and the rate of change is compared with a rate of change limit value and a modified frequency value is used to regulate the power output in the event of the rate of change limit value being exceeded.
