14.1.2 Application
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.
Figure 109 shows the topology of an IEC 61850–8–1 configuration. IEC 61850–8–1
specifies only the interface to the substation LAN. The LAN itself is left to the system
integrator.
