Abstract
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.
Claims10
A method of judging the energy level of a lightning strike in a wind turbine generator system generating electricity by driving an electrical generation mechanism through rotation of a rotor head to which a wind turbine blade is attached, wherein
- an electrically conductive shield tape is bonded to surfaces of the wind turbine blade to determine charge quantity (C) of a lightning strike from the size of a damaged area formed in the electrically conductive shield tape by the lightning strike.
A method of judging an energy level of a lightning strike on a wind turbine blade of a wind turbine generator system, wherein an electrically conductive shield tape is bonded to an outer surface of the wind turbine blade, said method comprising:
- determining a size of a damaged area caused in the electrically conductive shield tape by the lightning strike, and
- based on the size of the damaged area, judging a quantity of charge in the lightning strike to determine the energy level of said lightning strike.
