Method for controlling a wind turbine at high thermal loads

A method of controlling a temperature of a component of a wind turbine, the method comprising:

• defining a set point temperature of the component of the wind turbine;
• determining an actual temperature of the component;
• comparing the defined set point temperature and the determined actual temperature;
• and
• controlling the actual temperature of the component by controlling an output power of the wind turbine based on a result of comparing the defined set point temperature and the determined actual temperature.

A controlling device for controlling a temperature of a component of a wind turbine, the controlling device comprising:

• an input unit for defining a set point temperature of the component of the wind turbine;
• a determining unit for determining the actual temperature of the component;
• a comparing unit for the defined set point temperature and the determined actual temperature;
• and
• a control unit for controlling the actual temperature of the component by controlling the output power of the wind turbine based on the result of comparing the defined set point temperature and the determined actual temperature.
