DATA ACQUISITION AND CONTROL SYSTEM FOR AVERAGE VOLTAGE ELECTRIC SUB-STATIONS

摘要

The invention relates to a data acquisition and control system for average voltage electric sub-stations. According to the invention, the system comprises a number n of programmable units (CSPn) wherein there are implemented all the functions and interfaces necessary to allow the protection to operate, for the acquisition of the electric quantities and for the control of the switching elements specific to average voltage electric sub-stations, a number n of operation and displaying units (CMPn) equal to the number of programmable units (CSPn), representing the code of each electric cell comprised in the electric sub-station, a programmable automaton (AP) at the level of the average voltage sub-station, and a bi-directional serial bus which performs the data transfer between the programmable units (CSPn) at the level of electric cells and the programmable automaton (AP) at the level of average voltage electric sub-station, the programmable automaton (AP) ensuring the concentration of the data relating to the functioning of all elements of the sub-station, the processing thereof in a program implemented within the automaton and the transmission of the commands necessary to a good functioning of the sub-station in conformity with an internal functioning program, with the status of the interlocking between various execution elements and also with operators' requests.
