Previous issue date: 2017-07-06 / Este trabalho tem como objetivo propor uma Smart Grid composta por duas subesta??es para
a implanta??o da t?cnica de self healing utilizando o Simulador Digital em Tempo Real (RTDS
? Real Time Digital Simulator) e rel?s de prote??o IEDs (Intelligent Electronic Devices) com
comunica??o atrav?s da padr?o IEC 61850 entre eles. Nas redes el?tricas de distribui??o,
t?cnicas de recomposi??o autom?tica (self healing) podem ser usadas com o intuito de diminuir
os tempos com a perda do fornecimento de energia el?trica aos consumidores ocasionado por
curto-circuito, diminuindo assim os preju?zos aos consumidores e em decorr?ncia de multas. A
metodologia aplicada ? baseada na modelagem do circuito proposto no RTDS, que ?
monitorado em tempo real. S?o simulados v?rios tipos de curtos-circuitos em diferentes pontos
do sistema e, na ocorr?ncia de cada falta gerada, o programa desenvolvido analisa os dados do
sistema pr? e p?s falta, isolando o trecho do circuito afetado e ir? reconfigurar automaticamente
a rede de forma a restabelecer o fornecimento de energia para as cargas afetadas. A escolha do
arranjo final da rede, ap?s o processo de reconfigura??o autom?tica, ser? baseada em um
processo de otimiza??o intitulado Reconfigura??o por Soma de Pot?ncias ? RSP. A
comunica??o entre o RTDS e os IEDs (que fazem a prote??o de parte do sistema) utiliza o
padr?o IEC 61850 com troca de mensagens GOOSE (Generic Object Oriented Substation
Event) aplicando os aspectos relevantes desse padr?o. / This work aims to propose a Smart Grid composed of two substations for the implementation
of the self healing technique using Real Time Digital Simulator (RTDS) and IED (Intelligent
Electronic Devices) protection relays with communication through standard IEC 61850
between them. In distribution networks, self healing techniques can be used in order to reduce
the times with the loss of electricity supply to consumers caused by a short circuit, thus reducing
the losses to consumers and due to fines. The methodology applied is based on the proposed
circuit modeling in the RTDS, which is monitored in real time. Several types of short circuits
are simulated at different points in the system and, in each fault generated, the program
developed analyze the pre and post fault system data, isolating the section affected and
automatically reconfiguring the circuit to restore the power supply to the affected loads.
The choice of the final network arrangement, after the automatic reconfiguration process, is
based on an optimization process called Reconfiguration by Power Addition - RPA
.Communication between RTDS and IEDs (which protect part of the system) use the IEC 61850
standard with GOOSE (Generic Object Oriented Substation Event) message exchange applying
the relevant aspects of this standard.
