2. Localização de faltas em linhas de transmissão de múltiplos terminais a partir de registros oscilográficos sincronizados via transformada wavelet
The electric energy is essential to the development of modern society and its increasing demand in recent years, effect from population and economic growth, becomes the companies more interested in the quality and continuity of supply, factors regulated by ANEEL (Agência Nacional de Energia Elétrica). These factors must be attended when a permanent fault o

3. Desenvolvimento e implementação de um sistema de monitoramento em tempo real da tensão da rede com acesso remoto
Some years ago in Brazil the power quality was related, basically, with interruption of supplied energy and certain special loads of industry. In recent years, however, under controls of the regulating agency ANEEL (Agência Nacional de Energia Elétrica) and with specialists, the power quality area received the due attention and was legislated and acquired

4. Pre-corrective maintenance of power transformers: a new maintenance concept / Manutenção pré-corretiva em transformadores de potência: um novo conceito de manutenção
An important competitive edge of electric power distribution companies is their electric assets utilization management. Among them stands outs the power transformers because of its strategic importance in the energy supply to high demand areas. To minimize operational and social impacts associated to the electric energy supply interruptions these equipments

5. ELECTRIC DISTRIBUTION POWER SYSTEMS RELIABILITY OPTIMIZATION: An Approach Considering the Selection and Allocation of Protection and Switching Devices / OTIMIZAÇÃO DA CONFIABILIDADE DE SISTEMAS DE DISTRIBUIÇÃO DE ENERGIA ELÉTRICA: Uma Abordagem Considerando a Seleção e Alocação de Dispositivos de Proteção e Manobras
One of the main goals of the electric utilities is to provide energy to its customers in a reliable and low cost way. Traditionally, the electricity sector regulatory commissions impose continuity targets, which must be carried out, to avoid great penalties. For many years, the electric utilities have adopted the practice of allowing the increment of tempora

6. Impactos causados pela universalização do acesso e uso da energia elétrica
Public electric utilities have legal and contractual obligation to supply service to the market of their concession areas, without customer discrimination. New connections used to be accomplished partly with financial support of interested consumers, and the amount of investment of the distribution companies were established in regulations. This practice mad

7. Investigation of the real time communication problem with consumers during energy supply interruption in critical days. / Estudo do problema da comunicação em tempo real com o consumidor na situação de interrupção de fornecimento de energia elétrica em dias críticos.
Severe weather conditions such as hurricanes, lightning storms, etc. have the potential to seriously damage electric utility transmission and distribution systems. This type of damage will disrupt electrical service until the physical facilities can be replaced or repaired. Then large storms can result in a massive number of customer outages, sometimes takin

8. UM MODELO DE ANÁLISE ENVOLTÓRIA DE DADOS PARA ESTABELECIMENTO DAS METAS DE CONTINUIDADE DO FORNECIMENTO DE ENERGIA ELÉTRICA / A DATA ENVELOPMENT ANALYSIS MODEL TO SET ELECTRICITY SUPPLY CONTINUITY STANDARDS
In the Brazilian electric power sector, the distribution tariff revision is made by the price cap method. Since this approach encourages the cost reduction, the quality of supply can suffer deterioration. In this context, a quality supply regulation becomes more important. The continuity of supply regulation consists in setting upper limits or standards to t
