What is IEC 61850 GOOSE Message? GOOSE is a peer-to-peer communication between IEDs in the

substation network The 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

*FCDA: Functional Constraint Data Attribute

*FCD: Functional Constraint Data

FCDA and FCD FCDA:

a single data attribute, a sub data object or sub data attribute of a data object having a specific functional constraint (FC) value

Object reference:E01F11LP1/GGIO.Ind.stVal [ST]

FCD: The reference to an ordered collection of data

attributes of a data object having the same functional constraint (FC) value

Example:E01F34LC/MMXU.A [MX]

IEC 61850 GOOSE Message Parameter Mapping Data set:

a group of data attributes with specific functional constrain

Each of data attributes is called Member of the dataset

It can be:1. Configurable

2. Dynamic

3. Fix

IEC 61850 GOOSE Message-Conclusion

GOOSE messages are one of the key differentiators of IEC 61850

Client –Server communications are not suitable for protection applications

Peer-to-Peer communications can meet the protection performance requirements

Successful implementation of GOOSE based protection systems requires not only good understanding of the basics, but also planning and motivation
