Abstract

A method for operating a wind turbine (100) is specified, wherein the wind turbine has a rotor (10) with at least one rotor blade (1, 2, 3). The wind turbine is operable in a safety operation mode which is configured to slow down the rotation of the rotor. In the method, first information (I1) is representative of the operation mode in which the wind turbine is to be operated. The method comprises a step in which it is determined whether a first condition (C1) is fulfilled. The first condition comprises that a failure appears in the wind turbine during rotation of the rotor. If the first condition is fulfilled, second information (I2) is provided which is representative of the actual rotational speed of the rotor. Furthermore, third information (I3) is provided which is representative of the maximum allowable rotational speed of the rotor. Moreover, it is determined whether a second condition (C2) is fulfilled depending on the second and the third information. The second condition comprises that the actual rotational speed is at most the maximum allowable rotational speed. If the second condition is fulfilled, the first information is determined to be representative of the safety operation mode.Furthermore, a computer, a computer program, a computer-readable data carrier, a control device and a wind turbine are specified.
