Design and Implementation a Digital Teleprotection System

Protection systems have been used in order to detect commands and fix them in the high voltage line or network equipment. Correct commands reception and rapid response are necessary features for this type of systems. Teleprotection system acts as an interface between protection system and communication equipment. According to ready to use digital communication media in the electrical power industry, the need of teleprotection systems with capability to connect to this network is proposed. This paper describes the design and implementation of a digital teleprotection system in order to connect to digital communication network with line interfaces in accordance with ITU-T G.703 standard (64kbps and 2Mbps rates) or direct connection to optical fibers to transmit and receive maximum eight independent commands.
