Abstract |
This study focused on the effects of wind fluctuation on output performance of wind power facility. In general a windmill provides original output performance under a wind of less intensities of turbu...lence. According to our statistical analysis of NeWMeK data in 2007 at two representative observation points in Kyushu area, the occurrence frequency of wind of 0.2 or less intensities of turbulence at both observation points increased with mean wind speed. The wind power energy densities and annual productions of electrical energy from 500kW class windmills were estimated using those results. It was found that potential wind energy estimated using only wind records with small intensities of turbulence was smaller than those estimated using annual mean wind speed record.show more
