Implantação do Sistema de Monitoração de Vibração em Máquinas Elétricas em Alta Tensão

Abstract

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.
