Abstract
Methods of measuring a stall condition of a rotor of a wind turbine are disclosed. In one aspect a stall parameter is obtained on the basis of the power parameter and a thrust parameter; and the stall parameter compared with a threshold to determine a stall condition of the rotor.
Claims14
A method of measuring a stall condition of a rotor of a wind turbine, the method comprising:
- measuring a power parameter indicative of a power generated by the rotor;
- measuring a thrust parameter indicative of a thrust force generated by the rotor;
- obtaining a stall parameter on a basis of the power parameter and the thrust parameter, obtaining the stall parameter comprising dividing the power parameter and the thrust parameter;
- comparing the stall parameter with a threshold to determine a binary stall condition of the rotor, estimating of whether or not the rotor has stalled;
- and
- controlling the wind turbine in accordance with the stall condition.
