Pilot field test of intentional islanding in distribution network

Power supply interruptions to final customers are mainly caused by failures in the distribution system. The increase of distributed generation connected to the distribution system offers a possibility to reduce the duration and frequency of such interruptions as local generation can be used to feed local demand. This paper presents results of an actual implementation of an islanding operation for a rural feeder in Rio de Janeiro State, Brazil. A MW-scale electrical islanding, so-called minigrid, is formed when the utility circuit-breaker is opened, leaving part of the utility customers supplied solely by a 5.55 MVA synchronous machine based small hydro power plant. Field measurements were compared to simulation results obtained from a digital simulator developed to evaluate active distribution networks.
