Apparatus for monitoring wind turbine blade and method thereof

Abstract

Provided are an apparatus and method of monitoring a wind turbine blade. The method includes converting strain of a blade into moment, generating a reference value based on design information of the blade and statistical information of the moment, and comparing the moment with the reference value and determining a state of the blade. Accordingly, since the reference value serving as a reference of blade state determination is generated according to blade design information and moment statistical information and learning of the moment statistical information is performed, reliability of blade state determination can be improved, and thus, effective management and maintenance of the blade becomes possible.
