ABSTRACT:
The present invention is related to a method for determining a characteristic curve (9) for an electric variable (Pel, Q, φ, cos φ, IP, IQ) of a wind energy plant (1). According to the present invention, it is provided that at least one characteristic value of the electric variable (Pel, Q, φ, cos φ, IP, IQ) is measured for at least one value of the wind (vW), and for the at least one value of the wind (vW), a characteristic value of the electric variable (Pel, Q, φ, cos φ, IP, IQ) is adapted from a predetermined characteristic curve (7) containing characteristic values of the electric variable (Pel, Q, φ, cos φ, IP, IQ) as a function of different values of the wind (vW), taking into account the characteristic value measured for the at least one value of the wind (vW).
