An Integrated Station Local Control-Telecontrol System, in the Scenario of an Overall Telecontrol System

A distributed local control system which is easily integrated in an already existing telecontrol network and provides new features to the overall system is described. The system is a Local Area Network with a hierarchically structured tree topology. It can be connected by a Packet-Switching-Network or by dedicated links to several Control Centers, to other RTU's, to Teletex Terminals and to special purpose Maintenance Terminals provided by the system. These features allow for flexible management of the overall information generated by the Power System, and a large cost reduction in the wiring of the stations.
