碩士 === 清雲科技大學 === 電機工程研究所 === 95 === Wind speed observations of Ching Yun University in Jhong-Li are used to investigate the wind characters inside a megalopolis. Both the graphical and maximum likelihood methods are applied to estimate the shape and the scale factors of the Weibull wind speed distribution function. It is found that the graphical method always overestimate the occurrence probability of wind speed less than 2~3m/s. Based on the obtained wind speed distribution, the related capacity factors and normalized average power are analyzed to survey the optimum parameters of wind turbine generators. Our result suggests that the wind generator can obtain the maximum efficiency when the rated wind speed is 8~11m/s.
