Abstract

See full text

A method for detecting mechanical damage to a rotor blade of a wind turbine includes measuring vibrations of the rotor blade and generating a frequency-dependent vibration signal. A value of the signal energy over a predetermined frequency range of the vibration signal is determined at each of a number of measuring times and the respectively determined signal energy values are evaluated with respect to time in order to detect mechanical damage.
