1. Comparative analysis of voltage regulation strategies in power distribution systems with distributed generators / Análise comparativa de estratégias para regulação de tensão em sistemas de distribuição de energia elétrica na presença de geradores distribuídos
In order to assure that the installation of distributed generation would improve the operation of distribution and subtransmission networks, its technical impacts should be carefully studied, especially in distribution networks, which were originally designed to operate with unidirectional power flow. Among these impacts, the influence of distributed generat

2. Intelligent system to control voltage regulator relays / Sistema inteligente para controle de relés reguladores de tensão
This work presents an approach to voltage control in power distribution systems with load tap changers. Intelligent approaches are studied and applied in voltage regulator relay in order to improve the voltage profiles of the system. The proposal of this work is the addition of fuzzy modules in the conventional voltage regulator relays, which allows the expl

3. THE COST OF MAINTENANCE TRANSFER UNDER LOAD TAP OF THE TRANSFORMERS POWER OF EXTRA HIGH VOLTAGE THE ELETRONORTE / METODOLOGIA PARA REDUÇÃO DE CUSTOS NA MANUTENÇÃO DOS COMUTADORES DE TAP SOB CARGA DOS TRANSFORMADORES DE POTÊNCIA DE EXTRA ALTA TENSÃO DA ELETRONORTE
In this work a methodology for reduction of maintenance cost in the on-load tap changers (OLTC) of extra high voltage is proposed. The methodology is based on the use of Artificial Neural Networks (ANN) for the intelligent processing of input signals of the commutator. The neural nets adequately trained allow to create an information system and dedicated dia

4. VOLTAGE STABILITY PHENOMENON ANALYSIS: TRANSIENT AND LONG TERM TIME DOMAIN SIMULATION / ANÁLISE DO FENÔMENO DA ESTABILIDADE DE TENSÃO NO DOMÍNIO DO TEMPO: SIMULAÇÃO DOS PERÍODOS TRANSITÓRIO E DE LONGO-TERMO
This work is concerned with voltage stability analysis in time domain including transient and long-term time frames. Different power system stability forms are defined and classified according to the variable of interest and with the disturbance magnitude. Using a simple power system model, it is shown through dynamics formulations important aspects of the v
