Implementation of Telecontrol Applications over GPRS Networks

This article introduces GPRS (General Packet Radio Service) technology and examines its applicability to the sphere of telecontrol communications in an electric utility. In order to do so we will perform an analysis of the technology and its possibilities, telecontrol protocols, and give specific examples of why traditional telecontrol applications which function correctly over point-to-point serial links require a reformulation which optimises their function over a communications technology such as GPRS. It will also be analyzed whether this technology fulfils the reliability requirements expected by utility communications. More
