SYSTEM AND METHOD OF IN SITY WIND TURBINE BLADE MONITORING

摘要

Systems and methods are disclosed for monitoring parameters such as the material properties or structural integrity of a wind turbine blade on a wind turbine. An example method comprises detecting light reflected from a wind turbine blade, generating a value based on the detecting, comparing the value to a threshold value and determining a parameter of the wind turbine blade based on the comparing. A further embodiment comprises determining a wind velocity by detecting reflected light from a target area in front of the wind turbine blade. An example system comprises a detector configured to detect light reflecting from a turbine blade and to produce a value representative of the detected light. The system also comprises a comparator configured to compare the value to a threshold value and to determine a parameter of the turbine blade.
