IEC 61850 GOOSE configuration

All GOOSE configuration is performed via the IED Configurator tool available within the
MiCOM S1 Agile Support Software.
All GOOSE publishing configuration can be found under the 'GOOSE Publishing' tab in the
configuration editor window. All GOOSE subscription configuration can be found under the
'External Binding' tab in the configuration editor window. Care should be taken to ensure that
the configuration is correct, to ensure efficient GOOSE scheme operation.
Settings to enable GOOSE signalling and to apply Test Mode are available via the relay user
interface.

Ethernet functionality

Settings relating to a failed Ethernet link are available in the 'COMMUNICATIONS' column of
the relay user interface.
6.7.1

Ethernet disconnection

IEC 61850 'associations' are unique and made to the relay between the client (master) and
server (IEC 61850 device). In the event that the Ethernet is disconnected, such associations
are lost, and will need to be re-established by the client. The TCP_KEEPALIVE function is
implemented in the relay to monitor each association, and terminate any which are no longer
active.
6.7.2

Loss of power

The relay allows the re-establishment of associations by the client without a negative impact
on the relay's operation after having its power removed. As the relay acts as a server in this
process, the client must request the association. Uncommitted settings are cancelled when
power is lost, and reports requested by connected clients are reset and must be re-enabled
by the client when it next creates the new association to the relay.
