Wind turbine generator system and method thereof for judging lightning energy level

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 generating electricity by driving an electrical generation mechanism through rotation of a rotor head to which wind turbine blades are attached, an electrically conductive shield tape for judging the charge quantity (C) of a lightning strike is bonded to surfaces of the wind turbine blades.
