Projeto de um Aerogerador modelo Darrieus Tipo H utilizando um alternador automotiva

Abstract

The increasing electricity consumption by humanity, associated with the ge neration limit of traditional sources (hydroelectric and thermoelectric) and the de mand for more sustainable sources, creates the need to look for new sources of electrical energy. Two alternatives that have stood out are: wind energy and so lar energy. Energy from winds has been part of human history for thousands of years, being used to move mills, boats and pumping water even before the use of electricity. In this scenario, this work is inserted, with the objective of designing a small wind turbine, which can be reproduced without the need for large resour ces. The designed wind turbine consists of: a Darrieus-H type turbine, which was mathematically modeled and designed, but was not implemented in practice. And anautomotivealternatorasanelectrical generator, whichwaschosenbecauseitis easytoaccessandcanbefoundinautomotivestoresandjunkyards. Furthermore, a model was created in the Simulink software with the aim of observing the beha vior of the wind turbine and being able to carry out a more detailed analysis. The work managed to deliver a turbine project with all the dimensions necessary for its construction. It was also possible to carry out tests on the alternator, in which thenecessaryelectrical parametersweredetermined. Simulationhasproventobe very useful for detecting existing problems and improvements that can be made to the project. The design of a Darrieus type H wind turbine, using an alternator, proved to be effective in generating energy, but improvements can be made.
