ABB - Plant-wide autosynchronization using REX640

REX640, the newest member of ABB's Relion® protection and control family of relays, offers a variety of ready-made application packages to choose from, of which autosynchronization is one.
REX640 is able to manage the plant-wide autosynchronization system, including both generator and non-generator circuit breakers.
The REX640 relays interact using binary and analog GOOSE signaling as per IEC 61850-8-1 and share information on primary network switching status, generator availability, and voltage and frequency deviations across the circuit breaker under synchronization. Each circuit breaker has its own autosynchronizer in the related relay's functionality.
This makes autosynchronization with REX640 both simple and cost-efficient.
