Wind turbine generator and its method for judging energy level of thunderbolt

摘要

A wind turbine generator system that can quantitatively determine the energy of a lightning strike on a wind turbine blade is provided. In the wind turbine generator system 1 generating electricity by driving an electrical generation mechanism through rotation of a rotor head 4 to which wind turbine blades 5 are attached, an electrically conductive shield tape 10 for judging the charge quantity (C) of a lightning strike is bonded to surfaces of the wind turbine blades 5.
