    Despacho Econômico e Ambiental de Energia Elétrica Usando Técnicas Computacionais em LabVIEW: Uma Abordagem Multiobjetivo para Sistemas de Geração Termelétrica
    (INSTITUTO DE TECNOLOGIA, 2013) AZEVEDO, Raimundo Edney dos Santos; BEZERRA, Ubiratan Holanda; LEITE, Jandecy Cabral; AZEVEDO, Manoel Socorro Santos; NETO, Vilmar Domingos da Silva; MAGALHÃES, Edilson Marques
    This paper proposes an analytical strategy based on mathematical models to address the load dispatch problem in thermal power plants, simultaneously considering economic and environmental criteria. Using the computational tool LabVIEW, the study develops a multi-objective model that minimizes operational costs and pollutant emissions (SO₂ and NOₓ) while meeting energy demand. The results demonstrate the approach's effectiveness across different load scenarios, highlighting solutions that balance energy efficiency and environmental impact reduction.

    Implantação do Sistema de Monitoração de Vibração em Máquinas Elétricas em Alta Tensão
    (INSTITUTO DE TECNOLOGIA, 2013) SILVA NETO, Vilmar Domingos da; VIEIRA, João Paulo Abreu; LEITE, Jandecy Cabral; AZEVEDO, Raimundo Edney dos Santos; Prof. Dr. Carlos Tavares da Costa Júnior
    This paper presents the development and implementation of an online monitoring system for hydraulic generators operated by Eletrobrás-Amazonas Energia S/A. The system, called SIMME, was designed to evaluate critical physical parameters in 250 MVA rotating machines, using sensors, signal conditioners, and fuzzy logic-based software. The client/server architecture enables data transmission via intranet, providing continuous information to operation and maintenance teams. The system proved to be reliable, low-cost, and effective in fault detection, contributing to predictive maintenance and reducing unplanned downtime.
