Abstract
A method for operating a wind turbine is provided. The wind turbine includes a rotor with at least one rotor blade. The method includes determining an actual value of at least one of a first variable indicative of a failure state of the wind turbine and a second variable of the wind turbine correlated to a status of the wind turbine or an ambient status. The method further includes estimating an occurrence of a detrimental overspeed state of the wind turbine from at least one of the determined actual values, wherein a variable speed limit is adjusted based on the result of the estimation. The method further includes operating the wind turbine having regard to the variable speed limit. A control system for performing this method and a wind turbine including the control system is provided.
