1. A method for operating a wind turbine comprising a rotor with rotor blades of which an angle is adjusted by means of a turbine controller, in which a state variable which reflects a current thrust of the rotor is detected, comprising the steps of:
a) determining a short-term mean value of the state variable;
b) determining a difference between the short-term mean value of the state variable and the detected current state variable;
c) determining a first target blade angle correction value from the determined difference;
d) the turbine controller taking into account the first target blade angle correction value for the blade angle adjustment.
