Abstract

This paper presents the characteristics of lightning pver Jeju island and a case of emergency stop of a wind turbine due to lightning. Using the IMPACT ESP sensor to detect lightning, the data on lightning frequency, lightning strength, regional lightning event were obtained and analyzed in detail. The measurement period was for 3 years from 2004 to 2006. As a result, lightning occulted the most frequently in July and August. As for lightning strength, lightning with grades -4 to -6 and +3 to +5 occur ed more frequently. The eastern part of Jeju island had much more lightning frequency compared with the western part of it. Lightning with high grade occurred mainly in offshore site and the coastal region. Furthermore, the data on wind turbine stop caused by lightning was analyzed. Although wind turbine lightning damage was not much in this study, the investigation on lightning damage or lightning faults to a wind turbine should be conducted in Korea to increase availability of wind turbine.
