IEC 61850 quality expander QUALEXP

The quality expander component is used to display the detailed quality of an
IEC/UCA 61850-9-2LE analog channel. The component expands the channel
quality output of a Merging Unit analog channel received in the IED as per the IEC
61850-7-3 standard. This component can be used during the ACT monitoring to get
the particular channel quality of the Merging Unit.
The expanded quality bits are visible on the outputs as per IEC 61850-7-3 standard.
When written to IED, the configuration will show the expanded form of the
respective MU channel quality information during the online monitoring in the
ACT.
The validity status of the quality as described in IEC 61850-7-3 is expanded to
Good, Invalid, Reserved and Questionable (QUEST) outputs.
The detailed quality as described in IEC 61850-7-3 is expanded to Overflow, Out
of Range (OUTRANGE), Bad reference (BADREF), Oscillatory (OSC), Failure,
old data, inconsistent (INCONS) and inaccurate (INACC) outputs.
The source status of the quality as described in IEC 61850-7-3 is expanded to
Process and Substituted (SUBST) outputs.
The other quality statuses (Test, Operator Blocked (OPBLKD) and Derived) are
shown as they are.
