This thesis is concerned with the calculation of the power turbine. This turbine should be used in the automatic drive of the compressor used for compression of natural gas in compressor stations. Flight engine aeroderivate from the Rolls-Roye company, type RB211-22B, was used as gas generator. The main aim of the thesis is to summarize of the base atributes of the combustion turbines and aeroderivates. They are used for automatic engine, application a thermodynamic calculation of the power turbine, for reaction stage and basic strength calculations.

Along with that, in the last few years, the growth of investment in the sector of wind and solar power generation has stood out, which has contributed to supply for the needs faced by Brazil due to unfavorable hydrological conditions, which impair the production in the water power plants. Thus, a study was done on the technical and economic feasibility of the implantation of a small wind powerhouse in a grain warehouse, located in São João do Oeste, district of Cascavel-PR, to supply the power needs of such a building. Based on data provided by SIMEPAR, for every 10 meters of height, the annual/daily average of wind speed in the area was 4,12 m/s, the average temperature was 20,4 ºC and the average air pressure was 937,81 hPa, considering the last 5 years of measuring. Through the technical analysis and the cost survey, the decision was taken to use 3 turbines of 80 kW of power, at 30 meters of height, which would supply about 80% of the power needs in the place, generating credit in the months of low consume to be used in the months of higher use. However, the budget also proved to be unfeasible by the Net Present Value Method, the Internal Rate of Return and the Deducted Pay-Back as well, determining that at the end of the useful life of the turbines, the investment wouldn’t have been paid and it would be necessary to change the equipment, creating a debt over debt for the investor. Comparing the cost of such an investment in Brazil to other countries, a variation of 529% was observed, and the Brazilian cost for the system adopted is R$25.625,00/kW, while the foreign average is R$4.843,34/kW; Such a difference could be related to importation rate, taxes, reduced popularization and the competition between suppliers in Brazil / Uma das questões mais preocupantes no mundo contemporâneo é o uso demasiado de energia elétrica. Aliado a isso, nos últimos anos, tem se destacado o crescimento de investimentos nos setores de geração solar e eólica, que tem contribuído para suprir as dificuldades enfrentadas pelo Brasil com as condições hidrológicas desfavoráveis, que prejudicam a produção pelas hidrelétricas. Assim, realizou-se um estudo de viabilidade técnica e econômica da implantação de uma pequena central geradora eólica em uma unidade armazenadora e beneficiadora de grãos, situada em São João do Oeste, distrito de Cascavel-PR, para suprir as necessidades energéticas dessa edificação. Com base nos dados obtidos com o SIMEPAR, para 10 metros de altura, a média anual diária da velocidade do vento no local foi de 4,12 m/s, a temperatura média de 20,4 ºC e a pressão atmosférica média de 937,81 hPa, considerando-se os últimos 5 anos de medições. Por meio de análise técnica e do levantamento de custos, optou-se por utilizar 3 turbinas de 80 kW de potência, a 30 metros de altura, que supririam cerca de 80% das necessidades energéticas da unidade, gerando créditos nos meses de baixo consumo para serem compensados nos meses de maior utilização energética. Porém, o orçamento mostrou-se inviável pelo Método do Valor Presente Líquido, da Taxa Interna de Retorno e também do Pay-Back Descontado, determinando que ao final da vida útil das turbinas, o investimento ainda não teria sido pago e haveria necessidade de troca dos equipamentos, gerando dívida sobre dívida para o investidor. Comparando-se o custo do referido investimento no Brasil com valores de outros países, observou-se uma variação de 529%, sendo que o custo brasileiro para o sistema adotado resulta em R$25.625,00/kW, enquanto a média estrangeira é de R$4.843,34/kW, podendo essa diferença ter relação com a taxa de importação, impostos e reduzida popularização e concorrência entre empresas fornecedoras no Brasil
