  • Method for determining mechanical damage to a rotor blade of a wind turbine
    Patent number: 10466205
    Abstract: 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.
    Type: Grant

  • Method and device for monitoring a drive train of a wind power plant
    Patent number: 9459179
    Abstract: A method for monitoring a state of a drive train of a wind power plant. The drive train including at least one component which is mechanically connected to a rotating element of the drive train and at least one acceleration sensor connected to the rotating element and located at a distance from a rotational axis of the drive train. The at least one acceleration sensor is configured to rotate about the rotational axis of the drive train at the distance. A signal of the at least one acceleration sensor is sensed in terms of its timing at least one rotational speed of the rotating element and is examined for interference frequencies which correspond to damage in the drive train.
