A Communication Module For The Integrated Automation Of A Substation

Telecontrol devices supply the real data for dispatching center, which monitors and controls remote breakers and isolators in substations. This paper introduces the unmanned transformer substation integrated automatic system and puts forward a scheme of communication module. The error control theory and the coding of telecontrol information are discussed. Finally, the scheme and structure of hardware, key circuitry using 80C196KB single-chip computer, the scheme and ideology of software and flow chart of part software is introduced simply.
