Abstract

Wind turbines are often very high structures that are usually installed in high keraunic level areas. The keraunic level is the number of storm days per year. Therefore, windfarms are very vulnerable to lightning discharge. The damage due to a lightning strike can be reduced if the high current is quickly conducted to the ground.To date, wind turbine groundingsystemdesigns have been based on prior experience, without accurately studying transientgroundingsystem behavior.In this work, typical windfarmgroundingsystem geometries are analyzed in the context of lightning strikes.
