The current Ergon Energy telecommunications in the field for remote smart grid operations to its Automatic Circuit Reclosers (ACRs) uses public carriers such as Telstra mobile data services and Immarsat BGN network (Satellite).

The operational cost of using Immarsat BGN network is very costly ($8 per Megabyte) so there is financial incentive to investigate the use of the P25 Radio Modem Unit (RMU) to provide communications to ACR using existing the Ergon Energy P25 Radio Network.

This project aims to assess the capabilities of the P25 devices in the context of Ergon Energy’s operational requirements through both research and practical experimentation. The results will be used to identify and quantify (where possible) potential issues and make recommendations about any implementation.

The main aim is to use P25 RMUs over the Ergon Energy P25 Radio Network for communications to ACRs by benchmarking against the existing NextG modems in use. Communications must be implemented for two serial ports on the ACR, one for SCADA and the other for engineering configuration access.

The data and packet formats of the P25 communications protocol for both the SCADA DNP3 and engineering access connections have been documented. The operational requirements of the ACR SCADA and Remote Engineering connections have been identified. Following this a testbed was established and used to evaluate performance across a range of parameters. These were compared to the identified requirements.

The P25 RMU testbed assessed performance against the benchmarks established for the existing NextG modem application used on ACR. The P25 RMU worked with limitations which are to be outlined in the report on findings and hence recommendations to further improve the performance.
