Wind farm siting relies on in situ measurements and statistical analysis of the wind distribution. The current statistical methods include distribution functions. The one that is known to provide the best fit to the nature of the wind is the Weibull distribution function. It is relatively straightforward to parameterize wind resources with the Weibull function if the distribution fits what the function represents but the estimation process gets complicated if the distribution of the wind is diverse in terms of speed and direction. In this study, data from a 101 m meteorological mast were used to test several estimation methods. The available data display seasonal variations, with low wind speeds in different seasons and effects of a moderately complex surrounding. The results show that the maximum likelihood method is much more successful than industry standard WAsP method when the diverse winds with high percentile of low wind speed occur.

不同风的威布尔估计方法的比较

风电场选址依赖于风分布的现场测量和统计分析。当前的统计方法包括分布函数。威布尔分布函数是已知的最适合风的一种函数。如果分布适合该函数所表示的功能,则使用Weibull函数对风资源进行参数化相对简单,但是如果风的分布在速度和方向上各不相同,则估计过程将变得复杂。在这项研究中,使用101 m气象桅杆的数据来测试几种估算方法。可用数据显示季节变化,不同季节的风速较低,并且周围环境较为复杂。
