Abstract
This research aims to comparatively study the wind speed distribution at Tepha district in
Songkhla province in order to search the best methodology for describing the characteristics of
statistical wind speed. The statistical wind speed obtained from measurements at height of 120 m AGL
for 1 year in August 2014 to July 2015, was analyzed using on Weibull distribution and 3
methodologies to determine the scale and shape parameters, i.e., Maximum Likelihood, Least Square,
and WAsP to obtain the average wind speed. Wind power density and the ratio are also analyzed and
compared. Results show that the WAsP method is the best method to analyze the average wind speed
with the highest accuracy and close to the average of the statistical analysis followed by the Maximum
Likelihood and Least Square methods respectively.
Keywords
: Wind Energy, Wind Speed, Wind Power Density, Weibull Distribution
