METHOD FOR DETERMINING MECHANICAL DAMAGE TO A ROTOR BLADE OF A WIND TURBINE |
| 摘要 |
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. |

1. A method for identifying mechanical damage to a rotor blade of a wind turbine, comprising:
sensing vibrations of the rotor blade; generating a frequency-dependent vibration signal; determining in each case a signal energy measure, over a predefined frequency range of the vibration signal, at a number of measurement instants; and evaluating the respectively determined signal energy measures with respect to time, so as to identify mechanical damage. |
