1. Sistemas inteligentes para monitoramento e diagnósticos de falhas em motores de indução trifásicos / Intelligent systems for faults monitoring and diagnosis in three-phase induction motors
The objective of this thesis consists of the implementation of intelligent systems for three-phase induction motors fault diagnosis and condition monitoring. Therefore, an experimental test stand for stator winding inter-turn short circuit faults, broken rotor bar in squirrel cage and, finally, defective wheel bearing has been designed. The main focus is to

2. DIAGNÓSTICO DE FALHAS INCIPIENTES EM TRANSFORMADORES DE POTÊNCIA UTILIZANDO A TEORIA DA EXTENSÃO / FAULT INCIPIENT DIAGNOSIS IN POWER TRANSFORMERS USING EXTENSION THEORY
Power transformers play an important role in the power energy supply, demanding the continuous monitoring of process that could lead to operation faults, specifically in the equipment electric insulation. Methods considered in the standards IEC, IEEE and NBR7274 for dissolved gas analysis (DGA) do not provide good levels of accuracy, because there are scenar

3. Detecção e isolamento de falhas em sistemas dinâmicos baseados em redes neurais
This master dissertation presents the development of a fault detection and isolation system based in neural network. The system is composed of two parts: an identification subsystem and a classification subsystem. Both of the subsystems use neural network techniques with multilayer perceptron training algorithm. Two approaches for identifica-tion sta
