Abstract: Proposed is a wind turbine blade with a lightning protection receptor. The wind turbine blade with a lightning protection receptor is a technology that allows for excellent lightning capture rate for both negative and positive lightning by improving lightning measures for conventional wind turbines, which are vulnerable to positive lightning, in line with the increasing wind turbine heights for large-scale power generation and the trend toward offshore wind power, and that minimizes post-repair/supplementary measures by limiting blade damage/coating peeling due to lightning strikes to a narrow area, unlike in the conventional case where damage or peeling of the coating occurs over the entire area of a blade when struck by lightning on an edge wire inserted into the lateral inner side of the blade.
