Abstract: Presented by Martin Mc Caffrey at Metering, Billing/CRM India

One of Australia ‘s  largest electricity distributors has implemented the first large scale automatic restoration system . The business benefits from the system are provided by avoiding customer rebates payable for extended loss of supply.  The business case called for large savings in rebates payable if a system could be implemented to restore many common outages in under a minute as these momentary outages do not incur rebates.   This distributor undertook to implement with Oracle a solution using standard Oracle products and SCADA integration to implement such a system. 

The system uses real-time status from the SCADA and DMS to automatically detect faults and when detected to auto restore the faults using feeder tie points, with full calculation of loadings so that the restoration does not violate limits on the restoring or restored feeder section.  The system is implemented in the DMS/SCADA Master Station and requires no special hardware devices. The system has recently been rolled out live in production.
