Abstract
A method of operating a wind turbine and a wind turbine employing this method are provided. The method includes measuring an operating temperature in a plurality of components of the wind turbine yielding a plurality of measured operating temperatures. Each measured operating temperature is subtracted from a predefined maximum allowable operating temperature for the corresponding component of the wind turbine thereby yielding a plurality of operating temperature margins. A minimum operating temperature margin among the plurality of operating temperature margins is determined and at least one operating parameter of the wind turbine is set in accordance with the minimum operating temperature margin.

A method of operating a wind turbine, comprising:
- measuring an operating temperature in a plurality of components of the wind turbine yielding a plurality of measured operating temperatures;
- subtracting each measured operating temperature from a predefined maximum allowable operating temperature for the corresponding component of the wind turbine thereby yielding a plurality of operating temperature margins;
- determining a minimum operating temperature margin among the plurality of operating temperature margins;
- and
- setting at least one operating parameter of the wind turbine in accordance with the minimum operating temperature margin.
A wind turbine, comprising:
- a plurality of components, each component comprising a temperature sensor configured to measure an operating temperature of the component,
- a control unit, wherein each temperature sensor is connected to the control unit configured to carry out a method of operating the wind turbine, comprising:
- measuring an operating temperature in a plurality of components of the wind turbine yielding a plurality of measured operating temperatures;
- subtracting each measured operating temperature from a predefined maximum allowable operating temperature for the corresponding component of the wind turbine thereby yielding a plurality of operating temperature margins;
- determining a minimum operating temperature margin among the plurality of operating temperature margins;
- and
- setting at least one operating parameter of the wind turbine in accordance with the minimum operating temperature margin.
