Abstract
A Substation Automation (SA) system is configured to perform protection functions for a bay of an electrical power distribution substation, receive, via a communication link, redundancy protection commands from a remote center, and execute the redundancy protection commands for the bay. The SA system is configured to transmit to a redundant protection server of the remote center, process values measured by measurement equipment of the substation, and to receive, from the redundant protection server, and forward, via the process bus, the received redundancy protection commands directed to operating equipment of the substation. Thus, for multiple SA systems, redundant protection functions are implemented and provided cost-efficiently by one common remote central unit.
