Abstract: This paper analyses the wind speed of some major cities in province of Yazd which is located in central part of Iran. Also, the feasibility study of implementing wind turbines to take advantage of wind power is reviewed and then the subject of wind speed and wind potential at different stations is considered. This paper utilized wind speed data over a period of almost 13 years between 1992 and 2005 from 11 stations, to assess the wind power potential at these sites. In this paper, the hourly measured wind speed data at 10m, 20m and 40m height for Yazd province have been statically analyzed to determine the potential of wind power generation. Extrapolation of the 10m data, using the Power Law, has been used to determine the wind data at heights of 20m and 40m. The results showed that most of the stations have annual average wind speed of less than 4.5m/s which is considered as unacceptable for installation of the wind turbines. City of Herat has higher wind energy potential with annual wind speed average of 5.05m/s and 6.86m/s, respectively, at height of 10m and 40m above ground level (AGL). This site is a good candidate for remote area wind energy applications. But some more information is required, because the collected data for Herat is only for 2004. Cities of Aghda with 3.96m/s, Gariz with 3.95m/s, and Maybod with 3.83m/s annual wind speed average at height of 10m above ground level are also able to harness wind by installing small wind turbines. The Tabas and Bafgh sites wind speed data indicated that the two sites have lower annual wind speed averages between 1.56m/s and 2.22m/s at 10m height. The monthly and annual wind speeds at different heights have been studied to ensure optimum selection of wind turbine installation for different stations in Yazd. [Copyright &y& Elsevier]

Abstract: In this study, the 3-h period measured wind speed data for years 2003–2007 at 10m, 30m and 40m heights for one of the provinces of Iran. Semnan have been statistically analyzed to determine the potential of wind power generation. This paper presents the wind energy potential at five towns in the province – Biarjmand, Damghan, Garmsar, Semnan, and Shahrood. Extrapolation of the 10m data, using the Power Law, has been used to determine the wind data at heights of 30m and 40m. From the primary evaluation and determining mean wind speed and also weibull distribution, it is found that Damghan has better potential for using wind energy in the province. Thus concentrated on Damghan town and its sites – Moalleman, Haddadeh and also Kahak of Garmsar (only had Meteorological stop) using a 10-min time step wind speed and wind direction data for three measured heights. Between these sites, Moalleman is selected for a more accurate and spacious analysis. The objective is to evaluate the most important characteristic of wind energy in the studied site. The statistical attitudes permit us to estimate the mean wind speed, the wind speed distribution function, the mean wind power density and the wind rose in the site at the height of 10m, 30m and 40m. Some local phenomena are also considered in the characterization of the site. [Copyright &y& Elsevier]
