17.1 Communication protocols
Each IED is provided with several communication interfaces enabling it to connect to one or
many substation level systems or equipment, either on the Substation Automation (SA) bus or
Substation Monitoring (SM) bus.
Available communication protocols are:
• IEC 61850-8-1 communication protocol
• IEC/UCA 61850-9-2LE communication protocol
• LON communication protocol
• SPA communication protocol
• IEC 60870-5-103 communication protocol
Several protocols can be combined in the same IED.
17.2 IEC 61850-8-1 communication protocol
17.2.1 Application IEC 61850-8-1
IEC 61850-8-1 communication protocol allows vertical communication to HSI clients and allows
horizontal communication between two or more intelligent electronic devices (IEDs) from one
or several vendors to exchange information and to use it in the performance of their functions
and for correct co-operation.
GOOSE (Generic Object Oriented Substation Event), which is a part of IEC 61850–8–1 standard,
allows the IEDs to communicate state and control information amongst themselves, using a
publish-subscribe mechanism. That is, upon detecting an event, the IED(s) use a multi-cast
transmission to notify those devices that have registered to receive the data. An IED can, by
publishing a GOOSE message, report its status. It can also request a control action to be
directed at any device in the network.
