Análise para diminuição das perdas no processo de Geração de Energia Elétrica da UHE - Balbina.
(Instituto de Tecnologia, 2010) ARTEGA, Roland Céspedes; BLANCO, Claudio José Cavalcante; LEITE, Jandecy Cabral.; QUARESMA, João Nazareno Nonato
This article presents an analysis to standardize the performance of the turbines at the Balbina Hydroelectric Plant, located in Amazonas, Brazil, focusing on reducing head losses caused by the obstruction of water intake screens by wood from the flooded forest. The study proposes the installation of a containment net to prevent debris accumulation, minimizing unplanned shutdowns and associated costs with replacement thermal generation.
Análisis de la Implantación de Programas de Mantenimiento Total Productivo y Mantenimiento Predictivo para Mejoras en la Producción de Energía.
(Instituto de Tecnologia, 2011) FONSECA JUNIOR, Milton; BLANCO, Claudio José Cavalcante; MEDEIROS, Adelson Bezerra de; LEITE, Jandecy Cabral; AZEVEDO, Manoel do Socorro dos Santos; ESTEVES, Anderson Fernandes; MACIEL, Paulo Henrique de Lima.; CUNHA, Edinaldo José de Sousa
This paper describes procedures related to the implementation of Total Productive Maintenance (TPM) and Predictive Maintenance (MP) strategies in an electric power generation plant. The developed methodology aims to optimize performance and introduce improvements in the energy generation process, based on a case study conducted at an Eletrobrás Amazonas Energia plant. The results include a reduction in Mean Time Between Failures (MTBF) and Mean Time To Repair (MTTR), demonstrating the effectiveness of the applied techniques.
Análisis de los Impactos Armónicos en la industria de la electrónica utilizando árboles de decisión.
(Instituto de Tecnologia, 2012) NOGUEIRA, Rildo de Mendonça; OLIVEIRA, Edson Farias de; SILVA, Waterloo Ferreira da; SANTANA, Ádamo L.; TOSTES, Maria Emília de Lima; SOARES, Thiago Mota.; BRASIL, Davi do Socorro Barros
This study analyzes the impacts of current harmonics on the electrical grid of an electronics industry in the Manaus Industrial Park, focusing on the manufacturing of computers, notebooks, and tablets. Using power quality analyzers and decision tree techniques, the work quantifies the total harmonic distortion (THD) and identifies the most impactful harmonics, such as the 5th and 7th orders, generated by non-linear loads. The results demonstrate the effectiveness of the applied methodology to anticipate future regulations and improve energy quality.
Análisis estadístico comparativo de propiedades de aceites lubricantes usados en motores de combustión interna de una planta de generación eléctrica
(Instituto de Tecnologia, 2022) MARTÍNEZ OLIVARES, Adriana Cecilia; LORENZO ZÁRRAGA, Marcos Daniel; SALAZAR MARTÍNEZ, José Enrique
This work presents a comparative statistical study of the physicochemical properties of used lubricating oil samples from internal combustion engines in an electric power generation plant. The analysis is based on laboratory tests performed on 44 samples to determine the statistical significance of differences between oil brands and their relation to usage time. Normality tests, analysis of variance (ANOVA), and Tukey tests are used, revealing significant variations in properties such as viscosity, acid number, and metal content. The results support the hypothesis that lubricant performance depends on both the brand and the operating conditions.
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 Silva
This 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.
