New Enhancements in Radio Trials

New Enhancements in Radio Trials

At the 1996 IEEE/PES Transmission and Distribution Show, Alligator Communications led the first public demonstration of an enhanced, multiple-address (MAS) radio system which allows remote radios to self-arbitrate radio access. Designated as a “contention avoidance mode” of operation, the enhancements allow remote intelligent electronic devices (IED) to send relevant real-time information without the use of traditional polling methods. Coupled with the Utility Communication Architecture (UCA) protocols, this new ability will allow SCADA and distribution automation systems to operate in an unsolicited data delivery mode that will maximize data throughput and minimize radio bandwidth use.

The contention-avoidance mechanism to arbitrate the MAS communications takes advantage of protocol layers 1 and 2 of the UCA stack being implemented. In addition to contention avoidance, a second mode called enhanced polling is also available and demonstrated as part of the system. The enhanced poll mode allows the radio master to poll other IEDs while receiving information from another. The research and development of “contention avoidance” is sponsored by Electric Power Research Institute and the NRECA Rural Electric Research program. The project was performed as part of a DA/DSM Demonstration project at United Power Association (Elk River, Minn.). The core research and implementation was performed by a team of companies including Alligator Communications, SISCO and Power System Engineering.
