Quality signal of IEC 61850 communication
10.3.7
Quality information and its attributes are defined in the IEC 61850. Table 10.3-6 shows that
the relations between the definitions in the standard and signals prepared in the IED. The
quality attributes are influenced by the errors and alarms occurred in the IED, and the degree
of those errors are standardized by settings 'Error level' (see Chapter
The quality information is also affected by the test mode executed in the IED (see Chapter
Commissioning and maintenance

Note: M/N/O means rules of attributions. If it is Mandatory (M), it shall be used in the

IED. Optionally (O), or conditional mandatory(C) are used depending on the
environment states.
Note: The IED does not carry those attributes—overflow, out Of Range, oscillatory, old

Note: Three kinds of default quality information are defined in the IEDs of GR200:
3
(i) U16_00
(ii) U16_01
(iii) Qual_Validity
The U16_00 (i) is a default quality signal and it has been mapped in logical nodes
(LNs). For actual mappings in the IED, see
PIXIT, and TICS
Some detail quality attributes (e.g., overflow, outOfRange, etc. marked with "N")
are not included.
