Abstract
Within the framework of EU, security of energy supply, reducing energy costs for firms and citizens and the diffusion of alternative sources of energy are priority goals to improve environmental protection and sustainable development. In this light, the urban wind technology represents a new approach for the exploitation of this renewable resource, that is currently expanding but it represents still a niche market. This technology, for the differences in approach from the classical wind technology, requires a special analysis to characterize low speed winds and an improved research design to maximize energy yield at low wind speed. In the present work the analysis of wind resource in the site of the II Faculty of Economics, University of Bari, Taranto, Aldo Moro was carried out. By processing the data collected from a unit located on the roof of the Faculty we were able to identify the main regimes of wind and prevalent directions, theoretical energy yeld on the basis of technical data of urban wind turbines currently on the market. The results show that to maximize energy yield is necessary to take into account a variety of factors including: the technology used, the rated power, the characteristics of the power curve. The best performance is obtained from turbines that can produce high power at low wind regimes, regardless of power rating, a winning design feature but not yet widely available in today's market as manufacturers have concentrated their efforts in the manufacture of turbines not specifically created for urban use.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
