Energex is a South-East Queensland electricity distribution company supplying power to domestic and commercial consumers. Energex is considering implementation of automated software applications such as fault detection, isolation and restoration (FDIR) on its 11kV distribution network. FDIR could minimise supply interruption times, and ideally reduce the burden on human controllers, particularly accidental re-energising of faulted sections on the network. While the FDIR application could enhance Energex high voltage network operations, thorough testing and validation is required before implementation.

At the time of writing no Australian electricity distribution utility has implemented an in-service, algorithmic-based FDIR application. This project has enhanced knowledge through: development of an FDIR application and associated test device specific to a network; the processes for testing an algorithmic FDIR on a network; and the benefits and challenges of implementing an FDIR application.

The key outcomes of this work include the development of the test network, associated fault scripts, and the identification of current network limitations restricting the implementation of an FDIR application. The project is now ready for testing stage one of the application and is supported by technical documentation.

This project has enabled the development of the logic for governing this application and a suitable test network. Creation of the test scripts has permitted validation of the application and ensured its accurate testing after each upgrade of PowerOn Fusion, the distribution management system used by Energex. The test scripts are also the building blocks for testing further versions of the FDIR application.

The project has concluded there is further scope in the next version of the FDIR application to respond to additional network faults, considered more complex in nature, such as 11kV feeder circuit breaker fail conditions, mesh networks and the replacement of Substation SACS driven ACO schemes.
