Lightning detection system, wind turbine and a method to detect a lightning strike position and the lightning strength at a wind turbine

Abstract

Lightning detection system, wind turbine and a method to detect a lightning strike position and the lightning strength at a wind turbine The invention relates to lightning detection system (10) for detecting a lightning strike position and a lightning strength for a wind turbine (11), comprising: A lightning sensor unit (12) for detecting lightning strikes and collecting lightning data (27) of said lightning strikes, said lightning sensor unit (12) being mountable on a tower (13) of the wind turbine (11); at least one lightning strike counter (14) for collecting strike data (28) on a lightning strike count and a lightning strike time, when the energy of the lightning strike exceeds a certain threshold value, said at least one lightning strike counter (14) being mountable on a down conductor (15) on at least one blade (16) of the wind turbine (11); a processing unit (17) for collecting the lightning data (27) of the lightning sensor unit (12) and the strike data (28) of the at least one lightning strike counter (14) for processing the data to determine the position of the lightning strike.
