A system approach on power distribution supervisory control catalog

Abstract

The electrical energy distribution networks need remote control systems that are centralised and integrated as far as the functions they can develop are concerned. The need for a thinking unit at the line head for managing a Supervisory Control System is unavoidable. The thinking unit (microprocessor) moreover, allows a communication network to be built up which uses the line without voltage, with a variable number of transmitter-receiver stations attached to the equipped centres, as dis cussed in this paper. This paper considers a strstegy and the execution of a Supervisory Control System which adopts a dynamic polling structure and which is believed to be more attractive and economical than that adopted by rigid network structures. The following paragraphs discuss the configuration of the Distribution Network , the aims that the Supervisory Control System must fulfil, the system functions and a transmission system description.
