Overseas utilities have been employing Substation Automation Systems (SAS) based on IEC 61850 in which Generic Object-Oriented Substation Event (GOOSE) provides a fast mechanism of transferring event data such as transfer trip. The GOOSE messages are required to be reliable enough to maintain electric supply reliability, even though off-the-shelf devices composing SAS have their fixed configurations about GOOSE. This paper proposes a method to improve reliability of GOOSE with redundant dispatchers and message retransmissions that can use the fixed configurations as is. It also describes experimental results using a test system dispatching GOOSE messages of transfer trip, and shows the advantage of our proposal.
