Abstract

In this study, techno-economic and environmental feasibility analyses of a wind turbine for different hub connection heights were investigated using RETScreen Expert energy analysis program. Çerkezköy district of Tekirdağ province was chosen as the region in which the wind turbines will be constructed. According to the analysis of hourly wind speed data recorded by a meteorology station established in Çerkezköy, it can be easily said that the annual average wind speed for 10 m altitude is 5.305 m/s and the directions of the prevailing winds are between NE (45o) and ENE (67.5o). The model of the wind turbine chosen in the present study is the Sinovel 1500/77, and techno-economic and environmental evaluations were made for the hub connection heights of 65, 80 and 100 m. In accordance with the study results, when the payback period is evaluated in terms of energy production cost and greenhouse gas reduction potential, the wind turbine with 100 m hub connection height exhibits better results than others with 65 and 80 m. It is thought that this study will guide selecting a suitable hub height for wind power plants and wind turbines that are planned to be established in Çerkezköy, one of the largest industrial regions of Turkey to obtain cost-effective and environment-friendly conditions.
