Application of Weibull Distribution Function for Analyzing Wind Velocity Data in Xinier Reservoir

This paper calculated Weibull distribution parameters of wind speed with three methods and compared with them.Firstly introduced three common methods: the fitting method of cumulative distribution function,the estimation method of average wind speed and standard deviation,and the estimate of average wind speed and maximum wind speed.Then the Weibull parameters of Xinier reservoir area was calculated separately by three methods above.In order to check up the effect of three different methods,the calculated probability distribution of wind speed of Xinier Reservoir area compared with the actual frequency distribution of wind speed,the obtained fitting curves was applied to practice and a pseliminary evaluation to the wind energy resources development of Xinier Reservoir was done.
