Análise de viabilidade técnica e econômica para projeto proposto de turbinas VAWT em comparação a opções comercialmente disponíveis

Abstract

Coming from a personal curiosity and based on the strategic need to generate energy whose supply does not depend on the availability of water, due to the reduction in reservoir levels in Brazilian hydroelectric plants, it was decided to explore the field of renewable electricity generation through vertical axis wind turbines. Using a simulation tool, five vertical axis wind turbine, whose geometric and operating parameters were informed by the available literature, were proposed and compared to commercially available turbines. The paper presents the results of the technical and economic feasibility analysis of the five proposed projects, simulated with Wind regimen parameters for an altitude of one hundred meters in the cities of Londrina-PR, São Paulo-SP and Viçosa do Ceará-CE. Within the premises established within the paper, ten viable combinations of projects and locations were successfully found, whose payback values were all lower than the life expectancy of the equipment. With the lowest payback being less than six months in Viçosa do Ceará, with a potential energy generation of 24516 KWh per year for that project.
