Generally, wind energy production is based on the average wind speed without any classification. This article proposes a classification system on the basis of wind speed durations greater than a given threshold value. For this purpose, the wind quality designation (WQD) concept is defined based on the wind potential duration, amount, and intensity on a threshold level. Its classifications are depicted on five risk percentage classes as “excellent,” “very good,” “good,” “fair,” and “weak. Apart from the classification, the change of WQD with wind speed threshold provides qualitative and quantitative wind speed energy production assessment. The specific objective of the article is to present theoretical WQD explanations on the basis of the most frequently employed two-parameter Weibull probability distribution function (PDF). The application is provided for Adiyaman City, Kahta meteorology station wind speed records from the Southeastern province of Turkey. It is noticed that there is no “Weak” category at this station and the most effective quality class is “Excellent” from 14 m/s to almost 27 m/s wind speeds. The average wind speed corresponds to about 62% WQD. Finally, the wind speed potential durations PDF abides by the logarithmic-normal PDF, whereas amount and intensity accord with the Weibull PDFs.

风质量标识概念及应用

一般来说，风能发电是根据平均风速，没有任何分类。本文提出了一种基于大于给定阈值的风速持续时间的分类系统。为此，风质量指定 (WQD) 概念是基于阈值级别的风势持续时间、数量和强度来定义的。它的分类在五个风险百分比等级上被描述为“优秀”、“非常好”、“良好”、“一般”和“弱”。除了分类之外，WQD随风速阈值的变化提供了定性和定量的风速发电评估。这篇文章的具体目标是基于最常用的双参数威布尔概率分布函数 (PDF) 提供理论 WQD 解释。该应用程序是为土耳其东南部省份卡赫塔的阿德亚曼市气象站风速记录提供的。值得注意的是，该站没有“弱”类别，最有效的质量级别是从 14 m/s 到几乎 27 m/s 风速的“优秀”。平均风速相当于约 62% WQD。最后，风速潜势持续时间 PDF 遵循对数正态 PDF，而数量和强度符合 Weibull PDF。
