METHOD FOR DETECTING LIGHTNING STRIKES IN A WIND TURBINE ROTOR BLADE AND LIGHTNING STRIKE MEASUREMENT SYSTEM

摘要

A method for detecting lightning strikes in a wind turbine rotor blade (108) is provided. The wind turbine rotor blade (108) has a lightning protection system (150). A digital camera or an optical-digital heat sensor (210) is provided in the region of the rotor blade root, in a hub of the wind turbine or in or on a tower of the wind turbine in such a way that the digital camera (210) optically detects, at least in part, a portion of the lightning protection system (150). The portion of the lighting protection system is optically detected by the camera (210) in order to carry out optical temperature measurement. A temperature increase in the portion of the lightning protection system is detected on the basis of the optical detection by the camera.
