Abstract
The present paper reports performance measurements of a 300kW prototype wind turbine developed by Komai Tekko Inc., including new technical approach of site calibration technique. The site locates in the seaside industrial district facing Bay of Tokyo and there are many obstacles which potentially cause flow distortion. In Europe a wind turbine performance measurement is usually proceeded by an independent organization/institute, but there is no such an organization in Japan.Therefore, under cooperation among Komai Tekko Inc., Kyushu University, HIKARUWIND. LAB and AIST, the wind turbine performance measurement was conducted based on IEC standard combined with site calibration technique. Particularly, we applied two-dimensionalbinned site calibration methodology using flow correction factors which depend not only on wind direction but also on wind speed.
