Item Metodologia de diagnóstico de manutenção baseada em condição de enrolamentos estatóricos em hidrogeradores(INSTITUTO DE TECNOLOGIA, 2010) SANTOS, Renato Lelio da Silva; OLIVEIRA, Roberto Célio Limão de; LEITE, Jandecy Cabral; Edilson Marques MagalhãesThis paper presents a methodology applied at the Balbina Hydroelectric Power Plant to diagnose faults in stator windings of hydro generators, using partial discharge monitoring as a predictive maintenance tool. This technique enables the identification of insulation deterioration and supports decision-making based on reliable data, reducing costs, increasing reliability, and avoiding unnecessary maintenance. The methodology allows for more effective maintenance planning, extending equipment lifespan.Item Estudio de la influencia del ciclo de arranques y paradas en el estator de generadores síncronicos(INSTITUTO DE TECNOLOGIA, 2013) SANTOS, Renato Lélio da Silva; OLIVEIRA, Roberto Célio Limão de; LEITE, Jandecy Cabral; AZEVEDO, Manoel Socorro Santos; ESTEVES, Anderson Fernandes; MACIEL, Paulo Henrique de Lima; MAGALHÃES, Edilson MarquesSynchronous generators undergo frequent start-stop cycles due to maintenance or external factors, causing thermal variations that affect stator insulation. This study, conducted at the Balbina hydroelectric plant in Amazonas, Brazil, examines insulation aging trends in stators through partial discharge testing. Results indicate that continuous operation increases the generators’ lifespan.Item Analysis of lubricating oil in internal combustion engines of electrical power generation plant. Subtítulo: Análisis de aceite en motores de combustión interna estacionarios de planta de generación de energía eléctrica.(Instituto de Tecnologia, 2014) POZO-MOREJÓN, Juan A.; MARTINEZ-JIMENEZ, Boris L.; RODRÍGUEZ-RICO, Iván L.; MARTINEZ-MARTINEZ, Reinaldo; HERRERA-ARTILES, Arnaldo M.; LEITE, Jandecy Cabral.; BATISTA, Clauderino da SilvaThis study implements an integrated analysis procedure for lubricating oil in stationary diesel engines of an electric power generation plant, using the SACODE methodology with modifications to variable limits and evaluation of kinematic viscosity and TBN through Fuzzy logic. The method was automated by the SOFTLUB software, developed in MATLAB, enabling the monitoring of historical parameters, predicting future behaviors, and supporting maintenance decision-making.Item Análise Energética do Sistema de Resfriamento de uma Planta de Compressores de Ar Modelo ZH9000(Instituto de Tecnologia, 2015) FREIRE, Wildemar de Aguiar; BRAGA, Eduardo de MagalhãesThis study evaluates the cooling system of ZH9000 air compressors in an alumina refinery, addressing overheating and energy inefficiency. The proposed solution involves plate heat exchangers to isolate the water circuit, minimizing contamination and enhancing thermal performance. Findings suggest annual savings of R$600,000 and lower maintenance costs, with a 10-month payback period.
