1. Sistema inteligente para alocação eficiente de dispositivos indicadores de falta em alimentadores de distribuição / An intelligent system for efficient allocation of fault indicators in distribution feeders
Fault Indicator (FIs) devices have contributed to improve the location of faults on primary feeders, and consequently the reliability of distribution systems. However, one of the main problems facing their installation in a large scale in a distribution system is the lack of efficient methods to analyze big networks and to pinpoint exactly on which buses the

2. Alocação otima de reguladores de tensão em redes de distribuição de energia eletrica / Optimal placement of voltage regulators in distribution systems
This dissertation reports the development of a heuristic method for sizing and allocating voltage regulators in distribution radial primary feeders. The goals are to improve the voltage profile, to minimize the real power losses and to minimize equipment installation and maintenance costs. The proposed algorithm for the optimal allocation of voltage regulato

3. MÉTODOS PARA OTIMIZAÇÃO DOS AJUSTES DOS REGULADORES DE TENSÃO E ZONAS DE TAP EM SISTEMAS DE DISTRIBUIÇÃO / METHODS FOR OPTIMIZATION OF THE VOLTAGE REGULATORS AND TAP ZONES IN DISTRIBUTION SYSTEMS
The new regulations in the electric sector utilities have have requested greater efficiency and quality both in terms of continuity and in conformity of the energy supplied. Electrical equipments quality, efficiency and useful life depend directly of the power quality supplied. In addition to operation of equipments, supply of energy within the limits must b

4. Prevalência de exposição aos campos eletromagnéticos e justiça ambiental no município de São Paulo / Prevalence of exposure to electromagnetic fields and environmental justice in the city of São Paulo
The paper discussed the raising problem of risk in our current technological paradigm, their perception and tolerability, as well as their unequal distribution among the society. The fundamental assumption that emphasizes Environmental Justice refers to the hazards and risks disproportionately or unfairly distributed among the most vulnerable social groups,

5. Automatic fault diagnostic methodology in primary feeders of spot networkdistribution system. / Metodologia de diagnóstico automático de falhas de curto-circuito em alimentadores primários de sistemas de distribuição reticulados tipo Spot.
This work presents the development of an automatic failure diagnostic methodology for low impedance short circuit in mid voltage feeders of distribution spot networks systems. The developed methodology has the feature to identify the type of short circuit and its location. An Artificial Neural Network technique was employed. The parameters used to train the

6. PROJETO E IMPLEMENTAÇÃO DE UM CONTROLE MODULAR HCC PARA INTEGRAÇÃO DE FONTES ALTERNATIVAS DE ENERGIA / DESIGN AND IMPLEMENTATION OF A MODULAR HCC CONTROLLER TO INTEGRATE ALTERNATIVE SOURCES OF ENERGY
The experience of electric energy shortage in 2001 demonstrated that our dependence almost exclusively on hydroelectricity could fetch great problems to Brazil. Thus being, the existence of trustworthy alternatives of energy must exist, at the very least, as a reserve. For this reason, the perspective of decentralizing the energy production as a form of prom

7. Methodology for calculation of technical losses in each segment of the distibution system. / Metodologia para cálculo de perdas técnicas por segmento do sistema de distribuição.
This work focuses on the development of a new methodology for calculating technical losses within the different segments of the electric distribution system. In order to evaluate technical losses the electrical system was divided into eight segments: energy meter, customer connections, secondary feeder, distribution transformer, primary feeder, distribution
