Fusion networking technology for IEC 61850 inter substation communication

This paper explains how Fusion networking technology can be used as a communication mechanism between utility substations for transporting time critical traffic in wide area power system protection applications to attain deterministic low delay, zero packet loss and ultra-low packet delay variation. The requirements for inter substation communications are presented with focus on the IEC 61850 protocols of Generic Object Oriented Substation Event (GOOSE) and Sampled Values (SMV) and their adaptability to the traffic classes of guaranteed service transport (GST) and statistically multiplexed (SM) in Fusion networking technology.
