1.5MW 풍력발전시스템 출력 성능시험 및 불확도 분석

Abstract

The installed capacity of wind turbines in KOREA are growing and enlarging by the central government's support program. Thus, the importance of power performance verification and its uncertainty analysis are recognizing rapidly. This paper described the power testing results of a 1.5MW wind turbine and analysed an uncertainty level of measurements. The measured power curves are very closely coincide with the calculated one and the annual power production under the given Rayleigh wind speed distribution are estimated with the 4.7～22.0% of uncertainty but, in the dominant wind speed region as 7～8m/s, the uncertainty are stably decreased to 7～8%.
