Abstract
A method for determining an equivalent wind speed of a rotor blade plane of a wind power installation is provided. The wind power installation has a rotor with rotor blades that have adjustable blade angle. The method includes determining an electric internal power available in the wind power installation depending on a captured electric power and a captured rotational speed of the rotor. The method includes determining the equivalent wind speed depending on the determined available internal power and the captured rotational speed.
