| Abstract | ||
| The Weibull distribution is an important distribution especially for reliability and maintainability analysis. The suitable values for both shape and scale parameters of Weibull distribution are important for selecting locations of installing wind turbine generators. In this study, three methods were used to estimate the Weibull parameters (Shape and Scale), namely, Maximum Likelihood Method (MLM), Standard Deviation Method (MSD) and Least Square Method (LSM). These methods were compared for their performance and analysis of actual wind speed according to the criterion such as Root Mean Square Error (RMSE). In this study, (RMSE) values show that the maximum likelihood method performed is better than the standard deviation and least square methods for determining the value of (k) and (c) to fit Weibull distribution curves. Monthly mean wind speed and annual wind speed frequencies were calculated to note speed most available through year and high monthly mean wind speed | ||
