Abstract
In order to examine how the wind turbine power performance changes under the situation of complex terrain, the power performance testing was conducted on the A wind farm, Jeju Island, Korea. Topography of the A wind farm was assessed according to the International Standard, IEC 61400-12-1, which led to the fact that the A wind farm needs site calibration for power performance testing. Without site calibration, however, power performance measurement was conducted in accordance with the procedure provided by IEC 61400-12-1 and IEC 61400-12-2. The power curve was drawn using wind data from an 80 m-height met mast in compliance with IEC 61400-12-1, and it was also estimated using nacelle wind data from the wind turbine SCADA data in accordance with IEC 61400-12-2. Finally, measurement uncertainties were estimated for comparing uncertainty estimates from the two International Standards. As a result, the derived nacelle transfer function, NTF, did not meet the regulation for its validation. The comparison of Annual Energy Productions, AEPs, estimated by the met mast wind data and NTF showed that AEP-measured presented the difference between 1.2% and 2.4% and the difference of AEP-extrapolated ranged from 0.4% to 2.4%. That is, the derived NTF could not be used for another wind turbine power performance measurement since the difference should be within 1% regulated by IEC 61400-12-2. This result was caused by the difference of the two power curves estimated using the met mast wind data and the NTF, which came from not performing site calibration in this investigation. In addition, the magnitude of measurement uncertainty by IEC 61400-12-2 was two times that by IEC 61400-12-1.
