SA100 (Bay Control Unit) and SA200 (Bay Monitoring Unit) are the electronic units, Bay Unit, of the STCE family for substation automation. They are installed at the electrical stalls, are interconnected via optical LAN controlled by a station computer, and represent the ideal system for managers of high and very high voltage electricity networks, who need to renew the control and automation systems of the stations in order to maximize the efficiency and quality of the service offered.

The SA100 and SA200 systems guarantee:

– a unique, scalable and easily extensible architecture, based on the concept of interoperability between the various control, monitoring and protection units
– the automation, both centralized and distributed on the various stalls, no longer built with electromechanical relays but via software with standard IEC 61131 interface
– a 100 Mbit / s Ethernet standard station LAN with a single IEC 61850 standard protocol (client and server) which enables interoperability between the stall units and the protection relays, allowing the evolution over time of the individual systems or the integration with third-party systems
the integration of protections and IED devices equipped with standard buses or proprietary serial and parallel interfaces
synchronization of the entire system via GPS receiver, transmitted to the stall units via an optical network, independent of the Station LAN, based on the IRIG-B and NTP protocol
– ease of plant configuration through station workstations and in total safety
simple insertion of the station automation system into the hierarchically competent telecontrol network, with standard IEC 60870 protocols (101 client and 104 client) and with free access to all the information and functionalities necessary for the optimization of the electricity network and the its maintenance
– complete command and control of a stall
