چکیده

سرعت باد یکی از مهمترین مشخصه­های انرژی باد است که داده­های آن از ایستگاه­های هواشناسی استخراج می­گردد. در این مطالعه از داده­های اخذ شده از ایستگاه هواشناسی شهرستان اقلید در دوره ده ساله استفاده شده است. توزیع ویبل به عنوان بهترین توزیع با روش برازش منحنی و با استفاده از تخمین پارامترهای مهم آماری مشخص شد. نتایج نشان داد متوسط سرعت باد حدود 96/2 متر بر ثانیه است و کمترین سرعت وزش باد متعلق به ماه­های گرم سال است. متوسط سرعت نامی برای استحصال حداکثر انرژی باد در ایستگاه مورد مطالعه حدود 81/7 متر بر ثانیه برآورد گردید. مجموع چگالی توان و انرژی باد در دوره ده ساله به ترتیب معادل 79 وات بر مترمربع در سال و 6723/657 کیلووات ساعت بر متر مربع در سال محاسبه شد. جهت باد غالب در منطقه به ترتیب با بیشترین سهم در جهت­های شرق و غرب شناسایی گردید.

چکیده [English]

Wind speed is one of the characteristics of wind energy which its data is extracted from meteorological stations. In this study, the data obtained from the weather station in the city Eqlid during a ten-year period has been used. Weibull distribution was chosen as the best distribution function using fitting tests and estimation of some statistical parameters. The results showed that the average wind speed was about 2.96 meters per second and the least wind speed occurs in the warm months. Average rating for extracting the maximum wind speed (Vemp) at the studied stations was about 7.81 meters per second. The total power density and wind energy were 79 Watts per square meter and 657.6723 kilowatt hours per square meter in a year, respectively. The dominant wind direction with the highest contribution in the region belonged to the directions of east, south and west.
