3. Estimador de variações de tensão de curta duração em sistemas elétricos de potência utilizando estratégias evolutivas. / Estimate short duration voltage variation using evolutionary strategies.
A methodology is herein proposed to estimate Short Duration Voltage Variation (SDVV) in electric power systems, caused by electrical faults. To attain this target, values recorded by measurement equipment in specific sites are used. In fact, there are few power quality meters installed in power networks, due to the high cost of such meters. Although these co

4. Comparison between experimental data and numerical modeling for the natural circulation phenomenon
The study of natural circulation phenomenon has been object of crescent interest in scientific community in recent years. The new generation of compact nuclear reactors uses natural circulation of the fluid as a residual heat removal cooling system in case of accident or shutdown. The objective of this paper is to present a comparison between experimental da

5. 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

12. Sistema inteligente baseado em árvore de decisão, para apoio ao combate às perdas comerciais na distribuição de energia elétrica
The increase in commercial losses in electric utility companies has been a reason of great concern for these companies. The main motives of the increase in these losses are two: fraud practiced by the consumers; and problems in the energy meters. Nowadays, to identify one of the two problems mentioned above, in-site inspections are required. However, due to
