    Desenvolvimento de um Modelo Matemático para a Avaliação da Eficiência da Combustão em Usinas Termoelétricas Operando com Gás e Alternando com Diesel
    (INSTITUTO DE TECNOLOGIA, 2015) AZEVEDO, Manoel S. Santos; LEITE, Jandecy Cabral; CARVAJAL, Tirso Lorenzo Reyes; RODRIGUEZ, Jorge Laureano Moya; RICO, Iván Leandro Rodriguez; DÍAZ, Pablo Romélio Roque; GOMES, Paulo Cezar Rocha.; Prof Dr. Walter Barra Junior
    The article presents a mathematical model developed to evaluate combustion efficiency in thermoelectric power plants operating with natural gas (NG) and alternating with diesel (HFO). The study was conducted in a plant transitioning to dual-fuel use, aiming to optimize energy efficiency and reduce pollutant emissions. The model covers stoichiometric, thermodynamic, and kinetic aspects of combustion, implemented in software for real-time analysis. Results demonstrated the model's feasibility in predicting engine performance and optimizing specific fuel consumption, with practical applications in plant operation.

    Um Algoritmo Evolutivo para Aplicação na Compensação da Potência Reativa em Redes de Distribuição de Energia Elétrica
    (INSTITUTO DE TECNOLOGIA, 2017) AZEVEDO, Alysson Roberto; AZEVEDO, Manoel S. Santos; LEITE, Jandecy Cabral; BEZERRA, Ubiratan Holanda; ABRIL, Ignacio Pérez; Prof. Dr. Carlos Tavares da Costa Júnior
    This article proposes the use of genetic algorithms for the multi-objective optimization of reactive power compensation in electric power distribution networks. The method aims to locate and size compensation units, such as capacitor banks and passive filters, to maximize economic benefits and maintain power quality indices according to Brazilian standards. The study includes the analysis of a real case in the Manaus Industrial Pole (PIM), demonstrating the approach's effectiveness in scenarios with low and high harmonic penetration.
