Resumo: | Initial estimates of the potential contribution of wind power in Brazil for selected areas are approximately of 143GW. This figure represents two times the total power already installed. In Brazil, wind power relates to hydroelectrical power in such way that when wind speeds are high and stable, reservoirs experiences low capacity in water volume. The project herein presented has its origins on the approval of sponsorship from FINEP, a governmental agency that provided grant to develop a 5kW windmill over a period of 30 months. Among the objectives of this project are the development of a new technology to be applied to windmills, by means of technological innovation. More specially, the main proposal was to evaluate wind turbines behavior numerically and experimentally, including its implementation in wind towers to generate 5kW.This is accomplished in detail x out performance of analysis of structural characteristics, aerodynamic, performance e viability on the use of new materials were performed. To this end, we shall defie a specific methodology to each area of knowledge. Aerodynamic analysis was performed by means of initial numerical simulation followed by experimental tests in wind tunnel. A detailed description of the experimental set up and procedures is provided in chapter 3. Chapter 4 deals with electrical parts of the project. At this point an apparatus was specifically designed and built in order to acquire relevant parameters, which describe the electrical generator, provided we can predict on some measure the electrical energy performance under three diferent operating conditions, namely, without load, loaded and charging batteries. A detailed description of 5kW prototype manufactured is presented along with an analysis of the results are presented at the end of this chapter. Finally, the whole set was completed and were performed. The complete Truck-test set of the windmill is composed by tower, generator, turbines, controlling system and safety system. Results obtained are in agreement with the expected. At this moment, the 5kW windmill finds itself in operation. The windmill is instrumented and equipped with an data acquisition system to consolidate reliability tests, which provide eficiency tests, noise determination and safety devices test performance. This set of data will confirm the global performance and consolidate the 5kW windmill. |

Isso equivale ao dobro de toda a capacidade da geração já instalada no país. No Brasil, a energia eólica tem uma sazonalidade complementar à energia hidrelétrica, porque os períodos de melhor condição de vento coincidem com os de menor capacidade dos reservatórios. O projeto desenvolvido neste trabalho nasceu de uma chamada pública do FINEP, e sob os auspícios do recém criado CEPER. Ao projeto foi incorporado um caráter investigativo, de contribuição científica original, resultando em um produto de tecnologia inovadora para aerogeradores de baixa potência. Dentre os objetivos do projeto, destacamos a avaliação experimental de turbinas eólicas de 5000 W de potência. Mais especificamente, dentro do objetivo geral deste projeto estão incluídas análise estrutural, análise aerodinâmica e análise de viabilidade de novos materiais a serem empregados. Para cada uma das diferentes áreas de conhecimento que compõem o projeto, será adotada a metodologia mais adequada. Para a Análise aerodinâmica foi realizada uma simulação numérica preliminar seguida de ensaios experimentais em túnel de vento. A descrição dos procedimentos adotados é apresentada no Capítulo 3. O Capítulo 4 é dedicado aos testes elétricos. Nesta etapa, foi desenvolvido um banco de testes para obtenção das características específicas das máquinas-base, como curvas de potência, rendimento elétrico, análise e perdas mecânicas e elétricas, e aquecimento. Este capítulo termina com a análise crítica dos valores obtidos. Foram realizados testes de campo de todo o conjunto montado. Atualmente, o aerogerador de 5kW encontra-se em operação, instrumentado e equipado com sistema de aquisição de dados para consolidação dos testes de confiabilidade. Os testes de campo estão ocorrendo na cidade de Campos, RJ, e abrangeram as seguintes dimensões de análise; testes de eficiência para determinação da curva de potência, níveis de ruído e atuação de dispositivos de segurança. Os resultados esperados pelo projeto foram atingidos, consolidando o projeto de um aerogerador de 5000W.Submitted by Boris Flegr (boris@uerj.br) on 2021-01-06T19:12:33Z No. of bitstreams: 4 Eden Rodrigues Nunes Jr Pt 1.pdf: 247191 bytes, checksum: f1c638f2070259d3b0e8574e2a292b6c (MD5) Eden Rodrigues Nunes Jr Pt 2.pdf: 5888030 bytes, checksum: 34b4cd895b3d4cafc450104b0f52ea15 (MD5) Eden Rodrigues Nunes Jr Pt 3.pdf: 5527755 bytes, checksum: 29805e19eb3515d42819e16aca474717 (MD5) Eden Rodrigues Nunes Jr Pt 4.pdf: 2957781 bytes, checksum: a1b3f6be94bbf65a8eb8dc9f58dd7add (MD5)Made available in DSpace on 2021-01-06T19:12:33Z (GMT).
