2. Modelo computacional de cortes para otimizar o potencial de geração de usinas hidrelétricas / Computacional model of cuts to optimize the potential to generate hydro power plants
The repowering of hydro power plants increases their generating capacity by improving the structure or changing equipment. It is a low cost alternative to improve the generation capacity comparing with the building of new plants. Repowering by changing the hydro-turbines is the focus of this work. By doing that, the efficiency of the energy generation proces

4. BIFUEL CONVERSION OF THERMAL POWER PLANTS UNDER UNCERTAINTY: A REAL OPTIONS APPROACH / CONVERSÃO DE TERMELÉTRICAS PARA BI-COMBUSTÍVEL EM AMBIENTE DE INCERTEZA: UMA ABORDAGEM POR OPÇÕES REAIS
In Brazil, despite the predominant participation of hydro power plants, some years ago, due to Thermo Power Priority Program (PPT), a large number of Natural Gaspowered plants were implanted. A lot of uncertainties are imposed to the players in the Brazilian Power Market, and one more risk arises: the Natural Gas offer. The bi-fuel conversion arises as an op

7. An operational policy for the mid term hydrothermal scheduling of the Brazilian interconnected power system / Uma politica operativa a usinas individualizadas para o planejamento da operação energetica do sistema interligado nacional
This work presents an operational policy for the mid term hydrothermal scheduling of the Brazilian Interconnected Power System (BIPS) based on the individual representation of the hydro and thermo power plants, the detailed representation of the plants? features and the indirect representation of the inflow stochasticity through a forecasting model. These ch

10. Comportamento dinamico de mancais de guia de hidrogeradores de grande porte / Dynamic behavior of large hydrogenerators guidebearings
This work is divided in two parts, one theoretical and other experimental. In the first part is presented a procedure, established from an analytical study of the Reynolds equation, to determine the oil film stiffness and damping coefficients of large hydro units guide bearings. It is applied to the upper guide bearings of the Itaipu Power Plant generating u
