Abstract
Lots of studies have been performed for improving the availabilities of wind turbines.
Although both wind turbine owners and manufacturers make efforts to improve the
availabilities, the calculating methods for the availabilities may be different from each
other, which may cause dispute between them. For this reason, IEC (International
Electrotechnical Commission) issued the IEC TS 61400-26-1 in 2011 in which
the methods of calculating the availability are stated in detail. However, there
are very little studies about how the availabilities of wind turbines are in
South Korea when the IEC TS is applied to wind turbines.
In this thesis, the availabilities of real wind turbines (No. 5 and No. 6) located
in Jeju were derived in compliance with IEC TS 61400-26-1. For calculating
the availabilities, the error and turbine status logs data, the working time data
and the out of environmental time data of the two wind turbines were used,
which were obtained from SCADA system. The operational availabilities and
technical availabilities were computed and compared with those of SCADA system.
The technical availabilities were 97.2 % for the No. 5 wind turbine and 98.0
% for the No. 6 wind turbine, while operational availabilities were 78.1 % ∼
78.7 % for the No. 5 wind turbine and 58.5 % ∼ 61.0 % for the No. 6 wind
turbine, which had big difference. The reason is as follows: the time for
maximum performance production and technical suspension is regarded as
working time for calculating technical availability, while suspension time is
taken to turbine stop time for computing operational availability. The
availabilities based on SCADA system were 97.0 % for the two turbines,
while technical availabilities of No. 5 and 6 wind turbines were 97.2 % and
98.0 %, respectively, which were very similar. Finally, the calculation of
availability based on the IEC TS was found to be very useful to assess the
real wind turbine's operating situation fairly.
