摘要
The invention relates to a method for determining an equivalent wind speed of a rotor blade plane of a wind power installation (100) having a rotor (106) with rotor blades (108) that are adjustable in terms of their blade angle, comprising the following steps: determining an internal electrical power (pava, dc) available at the wind power installation (100) according to a detected electrical power (pcc) and a detected rotational speed (omega) of the rotor (106) ) and determine the equivalent wind speed (vwind) according to the determined available internal power (pava, cc) and the detected rotational speed (omega).
