6185061850 Support for IEC 61850

ABB, Alstom and Siemens (A-A-S) are deeply engaged in the elaboration of the IEC 61850 standard.

Each of these companies will implement IEC61850 in its power automation products and systems.

A roadmap for the staged implementation of IEC 61850 has been defined in line with the progress of the standard.

To verify the implementation of IEC61850 of all three suppliers, joint interoperability tests have been specified.

The first test step has now been completed successfully.

6185061850 What is GOOSE?

GOOSE (Generic Object Oriented Substation Event)

It is a mechanism for the fast transmission of substation events, such as commands, alarms, indications, as messages

A single GOOSE message sent by an IED * can be received and used by several receivers

GOOSE takes advantage of the powerful Ethernet and supports real-time behaviour

It is used for e.g.

tripping of switchgear starting of disturbance recorder providing position indication for interlocking

* IED: Intelligent Electronic Device

One device (sender) publishes information, only the subscriber devices are receiving it.The reaction of each receiver depends on its configuration and functionality.

6185061850 Conclusion

An important part of the standard was tested successfully

39 cases have been tested within one week

The standardisation documents are well defined

Three major companies in the substation and substation automation business are on track with their implementation of IEC 61850

A-A-S is on track - and on the right way
