Method for operating a wind turbine and wind turbine

A control system for operating a wind turbine having a wind turbine component and a setting system which is configured to execute at least two different measures for reducing a likelihood of overloading the wind turbine component, the control system comprising:

• at least one sensor system configured to take measurements via which it is determinable whether the likelihood of overloading the wind turbine component exceeds a threshold;
• a control device including a processor and a non-transitory computer-readable storage medium having program code stored thereon;
• said program code being configured, when executed by said processor, to:
• provide first trigger information which is representative of whether the likelihood of overloading the wind turbine component exceeds a first threshold;
• generate a first output signal if the likelihood of overloading the wind turbine component exceeds the first threshold, wherein the first output signal is configured to cause the setting system to execute a first measure of the at least two different measures for reducing the likelihood of overloading the wind turbine component;
• provide second trigger information which is representative of whether the likelihood of overloading the wind turbine component exceeds a second threshold after the first measure has been executed;
• generate a second output signal if the likelihood of overloading exceeds the second threshold, wherein the second output signal is configured to cause the setting system to execute a second measure of the at least two different measures for reducing the likelihood of overloading the wind turbine component, such that the second measure is executed in the case that the first measure has not led to a sufficient reduction of the likelihood of overloading at least one wind turbine component;
• said control device being signally connectable to said at least one sensor system in order to provide said control device with the measurements of said at least one sensor system;
• and,
• said control device being signally connectable to the setting system in order to provide the setting system with the first output signal and the second output signal of said control device so that the setting system executes the first measure and the second measure in dependence upon the first output signal and the second output signal.

A wind turbine comprising:

• a wind turbine component;
• a setting system configured to execute at least two different measures for reducing a likelihood of overloading at least one wind turbine component;
• a control system for operating the wind turbine;
• said control system including at least one sensor system configured to take measurements via which it is determinable whether the likelihood of overloading the wind turbine component exceeds a threshold;
• said control system including a control device including a processor and a non-transitory computer-readable storage medium having program code stored thereon;
• said program code being configured, when executed by said processor, to provide first trigger information which is representative of whether the likelihood of overloading the wind turbine component exceeds a first threshold;
• generate a first output signal if the likelihood of overloading the wind turbine component exceeds the first threshold, wherein the first output signal is configured to cause the setting system to execute a first measure of the at least two different measures for reducing the likelihood of overloading the wind turbine component;
• provide second trigger information which is representative of whether the likelihood of overloading the wind turbine component exceeds a second threshold after the first measure has been executed;
• generate a second output signal when said first measure has not led to a sufficient reduction of the overloading of the wind turbine component and the overloading has exceeded the second threshold, wherein the second output signal is configured to cause the setting system to execute a second measure of the at least two different measures for reducing the overloading of the wind turbine component;
• said control device being signally connectable to said at least one sensor system in order to provide said control device with the measurements of said at least one sensor system;
• and,
• said control device being signally connectable to the setting system in order to provide the setting system with the first output signal and the second output signal of said control device so that the setting system executes the first measure and the second measure in dependence upon the first output signal and the second output signal.
