Abstract
Climatic changes and global warming resulting from the human activities and energy utilization, alerted the world about the irreversible consequences and the urgency to interfere in the current environment scenario, intensify research for other sustainable energy alternatives and establish limits for energy production and consumption. Among the most viable energy sources wind energy stands at the top of the list with dominated technology well accepted by population. In this paper, we propose a method for finding maximum annual energy production (AEP) by designing the wind turbine blade geometry for different wind speeds in Campinas region. An algorithm based on the Blade Element Momentum (BEM) method and Weibull distribution was developed on Matlab. The results show that the blade design with rated wind speed of 7 m/s, produced annual energy of about 20.453 MWh/year, with a probability of occurrence of wind speed of 4.3%. Therefore, determining the best geometry to increase the AEP, will contribute to energy production and will decrease the dependency on non-renewable energy sources.
