Study of Lightning Detection Method Using Acoustic Data

Abstract

Wind power generation systems are vulnerable to winter lightning in the coastal areas of the Sea of Japan. For preventing the spread of lightning damage and ensuring safety, lightning detection systems (LDSs) have been installed to immediately stop wind turbines when a lightning strikes on the wind turbine. However, many of LDSs in widespread use in recent years are expensive, and many of them have a single mechanism that detects lightning strikes based on the lightning current obtained by integrating the magnetic field. In this study, in order to develop a relatively inexpensive and accurate LDS, we investigated a lightning detection method that uses acoustic data from lightning strikes to determine whether a lightning strike has occurred.
