What is IEC 61850 GOOSE Message?GOOSE is a peer-to-peer communication between IEDs in the substation networkThe GOOSE message is repetitive transmission of the data (tripping, analog value, interlocking, alarm, status etc.)The GOOSE message type can convey data attributes organized in a dataset

Why to use GOOSE?Fast system/network wide distribution of input and output data valuesPublisher and subscriber mechanism less complexityMulticast/broadcast services supports simultaneous delivery of data to multiple physical devices using same network less wiring

IEC 61850 GOOSE Message-Conclusion

GOOSE messages are one of the key differentiators of IEC 61850Client Server communications are not suitable for protection applicationsPeer-to-Peer communications can meet the protection performance requirementsSuccessful implementation of GOOSE based protection systems requires not only good understanding of the basics, but also planning and motivation

A single DataSet can be used by multiple control blocks (and therefore the reference). The DataSet/DataSetReference allows the receiver to understand what data information is being sent in a GOOSE. When no data change occurs, the GOOSE message is transmitted periodically according to set MaxTime. Periodic transmissions enable the monitoring of GOOSE communication. When one or several of the data attributes within the GOOSE dataset change, the first transmission with the updated data values is send within the configured MinTime. After the first transmission the same GOOSE message is retransmitted a number of times until the stable condition time is achieved. This enables the supervision of GOOSE communication, which was not possible with hardwired solutions. The receiver can detect communication losses if the periodically sent message disappears. The actual detection of communication loss is detected according to a parameter called TimeAllowedToLive. The relation between this parameter and MaxTime is not defined in the standard, and is therefore manufacturer and product specific. MinTime and MaxTime are defined in the GOCB. Values for MinTime and MaxTime are application specific, for example 10 and 1000 milliseconds respectively. The breaker failure initiation signal is sent through a set of data in one ethernet packet.
