Abstract
Provided is a method of estimating a value of wind speed a wind turbine is subjected to, the wind turbine having a rotor with rotor blades at least one having an adaptable flow regulating device installed, the method including: obtaining values for power output of the wind turbine, rotor speed of the rotor, and pitch angle of the rotor blades; obtaining state information of the adaptable flow regulating device; and estimating the value of the wind speed based on the values for power output, rotor speed, pitch angle and the state information of the adaptable flow regulating device.

A method of estimating a value of wind speed a wind turbine is subjected to, the wind turbine having a rotor with rotor blades at least one having an adaptable flow regulating device installed, the method comprising:
- obtaining values for power output of the wind turbine, rotor speed of the rotor, and pitch angle of the rotor blades;
- obtaining state information of the adaptable flow regulating device;
- and
- estimating the value of the wind speed based on the values for power output, rotor speed, pitch angle and the state information of the adaptable flow regulating device.
An arrangement for estimating a value of wind speed a wind turbine subjected to, the wind turbine having a rotor with rotor blades at least one having an adaptable flow regulating device installed, the arrangement comprising:
- an input module adapted to:
- obtain values for power output of the wind turbine, rotor speed of the rotor, and pitch angle of the rotor blades;
- obtain state information of the adaptable flow regulating device;
- and
- a processor adapted to estimate the value of the wind speed based on the values for power output, rotor speed, pitch angle and the state information of the adaptable flow regulating device.
