Substation Automation System with Redundant Configuration

Toshiba’s GSC1000 Substation Automation System, based on the IEC 61850 standard, now supports optional redundant configurations. The figure shows an example system in which each bay is now served using a two-port BCU and protection relays connected to alternate Ethernet Local Area Networks (LAN).

The two ports for each device are configured in a Hot Standby arrangement, with the status of each being recognized not only by the station computer (SAS server) but also by the BCUs themselves. This configuration further enhances reliability and operational safety for the most demanding of system requirements.
