Abstract
A process for monitoring a drive train component (22) of a wind power plant (10) with a rotor (12), the rotor rpm being detected, the wind power plant being controlled such that the rotor rpm rises during an acceleration phase, during the acceleration phase vibration signals being detected by at least one vibration sensor (30) attached to the drive train component in order to detect vibration spectra at different rotor rpm, and the vibration spectra detected at different rotor rpm being displayed as a superposition spectrum in order to evaluate the state of the drive train component.
