1. INTEROPERABILITY Tests IOP11/2002 1 IEC 61850 Interoperability with IEC 61850 IEC 61850 INTEROPERABILITY BETWEEN ABB, ALSTOM and SIEMENS STATUS REVIEW November 2002 IEC 61850 the global standard for communication in substations

2. INTEROPERABILITY Tests IOP11/2002 2 IEC 61850 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.

5. INTEROPERABILITY Tests IOP11/2002 5 IEC 61850 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

6. INTEROPERABILITY Tests IOP11/2002 6 IEC 61850 IEC 61850 GOOSE Principle GOOSE Sender Device X GOOSE Receiver Device Y GOOSE Receiver Device Z Ethernet One device (sender) publishes information, only the subscriber devices are receiving it. The reaction of each receiver depends on its configuration and functionality. EXAMPLE: GOOSE message
