Item 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 JúniorThis 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.Item Avaliação da Implementação do Sistema de Monitoração de Vibração em Unidades Geradoras da UHE – Balbina como Ferramenta de Manutenção Preditiva(Universidade Federal do Pará, 2015) SILVA NETO, Vilmar Domingos; VIEIRA, João Paulo AbreuAs the development of the electrical power market, the maintenance automation has become an intrinsic need to increase the overall economic efficiency of hydropower plants. This dissertation presents an assessment of the implementation of a predictive maintenance system of electrical machines (SIMME) on Balbina hydroelectric power plant in Amazonas, Brazil. The system was elaborated to predict defects, failures or bad operational states of machines of the hydroelectric plant and suggest maintenance intervention and operational emergency actions. The results show that the SIMME improved the economic performance of the hydropower plant.Item Melhoria do Desempenho de Motores de Combustão Interna em Empresa de Geração de Energia - Via Implantação de Manutenção Preditiva(Universidade Federal do Pará, 2011) FONSECA JUNIOR, Milton; BLANCO, Claudio José Cavalcante, Ph.D.This work aims to describe the main issues related to implementation of TPM (Total Productive Maintenance) and PM (predictive maintenance) in power plants using internal combustion engines. The two types of planning were presented with emphasis on maintenance activities. Currently the generation planning of the company do not allow unplanned outage. The most common faults were as a result of unbalance, misalignment, improper setting, coupling defective and contaminated oil. Issues that were eliminated with the implementation of predictive maintenance and implementation of a TPM program. Emphasis was placed on the importance of four pillars in this methodology (specific improvements, Autonomous Maintenance, Planned Maintenance and Education & Training). By the use of this methodology, it was shown some results achieved after its implementation such as: reducing the annual cost of maintenance, reduction of corrective maintenance, increase of MTBF (Medium Time Between Failures) and reduction of MTTR (Mean Time To Repair) in all areas of our plant. These results are reflected in the power generation and more reliability for our customers.
