ABB SAM600 Series - Quality Information in Sampled Values Streams; Merging and Bridging of SV Streams in a SAM600 System

2.3.4 Quality information in sampled values streams
GUID-6CBEE124-DFD0-4C29-B108-8C99B9B0C327 v1
Sample quality codes
Sampled values streams contain a "Health" information according to IEC 61850 in order to
indicate the validity of the transmitted information. The quality information contains several
attributes: a general validity code (2 bit), a detail quality code/source and a test (14 bit).
SAM600 uses the quality attributes as described in
Table 2.
Table 2: Usage of IEC 61850 quality codes in SAM600
Quality attribute Used value
Validity Good (0x0000)
Invalid (0x0001)
Detail Quality Bad Reference (0x0010)
Failure (0x0040)
Inconsistent (0x0100)
Derived (0x2000)
Source Substituted (0x0400)
Test Test (0x0800)
The resulting quality of a measured quantity in an IEC/UCA 61850-9-2LE is one out of the two
possible validity values. The other quality attributes can be a combination of the possible
values.
Sample quality indications
If a SAM600 module is configured for sending unmerged sampled value streams to its uplinks,
then the sample quality of the not contained quantity is set to
Invalid (quality code 0x0001)
and the sample quality of the contained quantity is set to
Good (0x0000). Detail quality values
for various conditions are listed in Table 3.
Table 3: Quality indications used by SAM600 modules
Quality Set under the following conditions
Invalid | Bad Reference Startup sequence of SAM600 module or source
stream of quantity for merging not in synch
Invalid | Failure SAM600 is not set to simulation mode and (A/D
converter not calibrated or SAM600-VT fuse failure
input is active )
Invalid | Inconsistent Source stream of quantity for merging not detected
or sample count not matching
Good | Substituted | Test SAM600 is set to simulation mode
Good | Test SAM600 is not set to simulation mode and Test
switch indication is active
Good | Derived SAM600-VT neutral phase and SAM600-CT neutral
phase only; if neutral phase is set to Calculated
Good | Substituted | Test | Derived If SAM600 module is in simulation mode and neutral
phase is set to Calculated
2.3.5 Merging and bridging of SV streams in a SAM600 system
GUID-01A8DB2E-C1B9-4BBD-8D89-F268203FB5D3 v1
The configuration of the SAM600 system regarding assignment of streams to access points is
performed with the SV Stream and Port Configuration tool in PCM600 (see Section 3).
