<p>A Substation Automation system (10) configured to perform protection functions (111, 121, 131) for a bay (11, 12, 13) of an electrical power distribution substation (1), particularly a medium-voltage substation (1), is further configured to receive via a communication link (31) redundancy protection commands from a remote center (2), and to execute the redundancy protection commands for the bay (11, 12, 13). Specifically, the Substation Automation system (10) is configured to transmit to a redundant protection server (20) at the remote center (2), process values measured by measurement equipment of the substation (1), and to receive, from the redundant protection server (20), and forward, via the process bus, redundancy protection commands directed to operating equipment of the substation (1). Thus, for the protection functions (111, 121, 131) of multiple medium voltage Substation Automation systems (10), redundant protection functions are implemented and provided cost- efficiently by one common remote central unit.</p> |
