Using TETRA for Remote Control, Supervision and Electricity Metering in an Electric Power Distribution System

摘要

An important part of the communication infrastructure in systems that cover large geographic areas and require maintenance and management of devices on remote locations - such as electric power distribution systems - is mobile radio communication. This is especially important on remote locations with no other communication means available. Besides the traditional voice communication, the new digital PMR systems also support various modes of data communication including the IP protocol. This offers new possibilities for remote data applications. In our paper, the possibilities of using a TETRA system for remote data applications such as remote control and supervision of breakers and disconnectors, and remote electric meter reading, are analyzed for the case of the electric power distribution company Elektro Ljubljana, d.d.
