Sampled Values
➢ Application ID
➢ GOOSE Control Reference
Any GOOSE message that fails these checks shall be rejected.
➤ Every received and validated GOOSE message that indicates a data
change, by an incremented status number, is evaluated as follows:
➢ Data within the received GOOSE dataset that are mapped to host
data bits are identified.
➢ Mapped bits are compared against a local version of the
available host data bits.
➢ If the state of the received bits is different than the local version:
➣ Update the local version with the new state for that bit.
➣ Pass the new state for the bit to the relay.
➤ Reject all DA contained in an incoming GOOSE based on the
presence of the following error indications created by inspection of
the received GOOSE:
➢ Configuration Mismatch: The configuration number of the
incoming GOOSE changes.
➢ Needs Commissioning: This Boolean parameter of the incoming
GOOSE is true.
➢ Test Mode: This Boolean parameter of the incoming GOOSE is
true.
➢ Decode Error: The format of the incoming GOOSE is not as
configured.
➤ The relay will discard incoming GOOSE under the following
conditions:
➢ After a permanent (latching) self-test failure
➢ When EGSE is set to No
Link-layer priority tagging and virtual LAN is supported as described in Annex C
of IEC 61850-8-1:2011.
GOOSE Performance
For outgoing high-speed data (as identified under GOOSE Processing), transmis-
sion of GOOSE begins within 2 ms of transition of digital data within the relay.
Note that you can include RAO points in outgoing GOOSE for high-speed trans-
mission—only the transition of a digital point will trigger the transmission within
2 ms. Please refer to Logical Nodes for data attributes that can trigger high-speed
GOOSE, if included in a dataset for outgoing GOOSE transmission. For all other
data contained in outgoing GOOSE, transmission of GOOSE begins within 500
ms of transition of data within the relay. Appropriate control commands are
issued to the relay within 2 ms of a GOOSE reception.
Sampled Values
NOTE: Not all SEL-400 series
products support SV.
IEC 61850 9-2, also known as Sampled Values (SV), describes a service that
brings digital analog samples from the substation yard to the control house. Mul-
tiple components are essential to successful implementation of such a service. SV
publishers, also known as merging units, locally sample and convert analog sam-
ples to digital samples with a time stamp. They then publish these samples with
