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.
