Datasets
Datasets are configured using
AC
SEL
ERATOR
Architect and contain data
attributes that represent real data values within the SEL-700G device. See
Logical Nodes for the logical node tables that list the available data attributes
for each logical node and the Relay Word bit mapping for these data attributes.
The datasets listed in Figure F.2 are the defaults for an SEL-700G device.
Datasets BRDSet01–BRDSet06 and URDSet01–URDSet06 are preconfigured
with common FCDAs to be used for reporting. These datasets can be
configured to represent the data you want to monitor. Dataset GPDSet01,
which contains breaker status and control data attributes, is used in the default
Goose Control Publication.
Figure F.2 SEL-700G Datasets
Within
AC
SEL
ERATOR
Architect, IEC 61850 datasets have two main
purposes:
➤
GOOSE—You can use predefined or edited datasets, or create
new datasets for outgoing GOOSE transmission.
➤
Reports—Twelve predefined datasets (BRDSet01 to BRDSet06
and URDSet01 to URDSet06) correspond to the default six
buffered and six unbuffered reports. Note that you cannot change
the number (12) or type of reports (buffered or unbuffered)
within
AC
SEL
ERATOR
Architect. However, you can alter the data
attributes that a dataset contains and so define what data an IEC
61850 client receives with a report.
Supplemental
Software
Examine the data structure and value of the supported IEC 61850 LNs with an
MMS browser such as MMS Object Explorer and AX-S4 MMS from Sisco,
Inc.
The settings necessary to browse an SEL-700G with an MMS browser are as
follows:
Time Stamps and
Quality
In addition to the various data values, the two attributes quality and t (time
stamp) are available at any time. The relay determines the time stamp when it
detects data or quality change.
NOTE:
Do not edit the dataset
names used in reports. Changing or
deleting any of those dataset names
will cause a failure in generating the
corresponding report.
