Abstract
In order to minimize the lightning damage to wind turbines, lightning
protection strategies for wind turbines from IEC Standard, Europe, USA, Japan
and Korea were reviewed and the strategies available in Korea were proposed
in this work. Also the lightning characteristics of the established and the
scheduled wind farms of Jeju Island as well as entire Jeju Island were
analyzed in detail. The lightning data for 10 years from 2003 to 2012 was
obtained from IMPACT ESP which detects lightning. Lightning frequency,
lightning strength and regional lightning events were analyzed in detail, and
then the lightning maps of Jeju Island were created. The evaluation of
lightning rate was made for all the wind farms of this study. The lightning
damage cases to wind turbines were investigated in the existing wind farms of
Jeju Island. Furthermore, lightning counters were installed in wind turbines to
detect electrical surge by lightning strike. The results obtained are as follows:
First, it is necessary to apply some good lightning protection strategies from
IEC Standard and other countries to Korea. Those are as follows: The
guideline for lightning protection for wind turbines should be established based
on IEC Standards. Both development of software and experimental studies
should be conducted for understanding the types of lightning damage to wind
turbines and compiling the database. For minimizing the lightning damage to
wind turbines, it is a key factor for wind farm owners and researchers to open
the information about the damage cases and wind farm operation technique to
the public.
Second, the eastern part of Jeju Island had more lightning frequency than the
western part of the Island. Also, the evaluation of lightning rate was good for
all the established and the scheduled wind farms of Jeju Island. Hankyung
wind farm is the best place for lightning safety, while precaution should be
taken against lightning damage in Samdal wind farm. There were two
lightning damage reports at Haengwon and Samdal wind farms, which were
the damage to wind turbine blades and the electric device of a turbine.
Finally, the electrical surges were detected in seven wind turbines of Gasi
wind farm by lightning counters. However, the surges were not caused by
lightning strike to the wind turbines.
