WIND TURBINE GENERATOR AND ITS METHOD FOR JUDGING ENERGY LEVEL OF THUNDERBOLT

摘要

A wind turbine generator which can know the energy of thunderbolt striking the wing of a wind turbine. In the wind turbine generator (1) generating power by driving a power generation mechanism through rotation of a rotor head (4) to which the wing (5) of a wind turbine is fixed, a conductive shield tape (10) for judging the quantity of charges C of thunderbolt is stuck to the surface of the wing (5) of a wind turbine.
