Abstract
Provided is a method of correcting a measurement value of least one wind characteristic, in particular wind speed and/or wind direction, related to a wind turbine having a rotor with plural rotor blades at least one having an adaptable flow regulating device installed, the method including: measuring a value of the wind characteristic; obtaining state information of the adaptable flow regulating device; and determining a corrected value of the wind characteristic based on the measured value of the wind characteristic and the state information of the adaptable flow regulating device.
Claims15
A method of correcting a measurement value of least one wind characteristic, related to a wind turbine having a rotor with plural rotor blades at least one having an adaptable flow regulating device installed, the method comprising:
- measuring a value of the wind characteristic;
- obtaining state information of the adaptable flow regulating device;
- and
- determining a corrected value of the wind characteristic based on the measured value of the wind characteristic and the state information of the adaptable flow regulating device.
A method of controlling a wind turbine, the method comprising:
- performing a method of correcting a measurement value of least one wind characteristic;
- and
- controlling the wind turbine based on the corrected measurement value of the wind characteristic.
An arrangement for correcting a measurement value of least one wind characteristic, related to a wind turbine having a rotor with plural rotor blades at least one having an adaptable flow regulating device installed, the arrangement comprising:
- a sensor adapted to measure a value of the wind characteristic;
- an input module adapted to obtain state information of the adaptable flow regulating device;
- and
- a processor adapted to determine a corrected value of the wind characteristic based on the measured value of the wind characteristic and the state information of the adaptable flow regulating device.
