摘要: The main objective of this paper was to analyze the statistical wind data obtained from measurements for 12 months period January December 2008 at Thasala district in Nakhon Si Thammarat province, southern Thailand. speed heights 20 m, 30 and 40 m above ground level were measured using 3-cup anemometers attached booms on a 45 lattice met tower. recording interval 10 min. set analyzed Weibull distributions order investigate shape scale parameters. parameters WAsP 9.0 analysis as well probability density function cumulative distribution graphical methods compared mean bias error between determined. Results showed that monthly parameter range 1.1-2.8, while 2.27-5.94 m/s corresponding speeds 2.2-9.4 m/s. determined by observational 2.4-7.8 m/s, 2.7-8.3 3.1-8.8 respectively. power 5.8-480.3 W/m2 class ranging 1- 4+. strong sufficient winds generation occurred during July month October.
