| Outline of Final Research Achievements |
In this research, we developed a new inexpensive lightning strike prediction technology to reduce the damage caused by lightning strikes in wind power generation to a fraction of the current level. The technology to reduce damage caused by lightning strikes is to detect the radio waves from the discharge from the tip of the wind turbine 30 seconds before the lightning strike and stop the wind turbine. Stopping the windmill can reduce the number of lightning strikes by 80% or more. It was confirmed that almost 100% of the radio waves due to the discharge from the tip of the wind turbine could be detected more than 30 seconds before the occurrence of a lightning strike. Furthermore, we have obtained many new findings by using the developed three-dimensional visualization system of radio wave radiation sources.
