IEC 61850-7-2 describes the services in the standard. IEC 61850-8-1 describes how the services are
applied in the communication. The conformance documents contain the description of the supported
services in the IED.
Services that are not mentioned in this chapter or in the conformance document are not supported by
the IED.
GOOSE simulation is supported according to IEC 61850 7-2.
If
LD0.LPHD1.Sim.stVal
is set to
true
, the incoming GOOSE with test-bit in the GOOSE header set
is treated as a real GOOSE. The real GOOSE is discarded as soon as a GOOSE with test-set is
received. When
LD0.LPHD1.Sim.stVal
is set to
false
, the real GOOSE is active again and GOOSE
with test-bit set is discarded.
Data set
Define data sets by the SCD description.
Create data sets under LD0 / LLN0 .
For more information on data sets, see the PIXIT-related documents.
Substitution
Substitution is supported for the respective DATA, according to IEC 61850-7-4 , that have the
substitution attributes defined.
Setting group control block
There is only one setting group control block, which is located in LD0/LLN0 (Logical Device0/Logical
Node 0).
Note that the actual number of used setting groups is defined by the parameter
MaxNoSetGRP
in the function
SETGRPS
, which is configured in PST in PCM600 .
But six setting groups is the maximum and it cannot be exceeded.
Generic object oriented substation event (GOOSE)
The structured GOOSE is supported. This means that the data sets can be defined with FCDA as
well as explicit attributes.
The supported data types to be published and received over GOOSE are binary values, double point
values, integer values and measured values, together with their quality. One signal is available inside
the application to validate the reception of a GOOSE message. The GOOSE signal is invalidated
when GOOSE messages are not received before 2*TAL(Time Allowed to Live).
GOOSE with TAL= 0 ms is treated as GOOSE with TAL = 100 ms and accepted.
Note that the data sets that are used or referred to by GOOSE control blocks can
only include a data attribute once. In other words, there may not be the same data
attribute in more than one data set.
