!PPENDIX% Detailed CGCM Unit Tag Descriptions
•
BusA_PhOffset - This tag configures a phase angle added to the measured
bus A phase angle. It is used to compensate for phase shift across sensing
transformers.
•
BusA_V_Scaler - This tag configures a multiplier by which the measured
bus A voltage is multiplied. It is used to compensate for ratio error across
sensing transformers.
•
BusB_PhOffset - This tag configures a phase angle added to the measured
bus B phase angle. It is used to compensate for phase shift across sensing
transformers.
•
BusB_V_Scaler - This tag configures a multiplier by which the measured
bus B voltage is multiplied. It is used to compensate for ratio error across
sensing transformers.
•
BusA_B_Select – This tag selects which reference bus the CGCM unit
attempts to synchronize to.
•
V_Match Gain-This tag sets the Proportional Gain parameter for Voltage
Matching mode
3YNCHRONIZING/UTPUTSFROMTHE#'#-5NIT
•
SyncDeadBus - This tag indicates all conditions have been to allow a
DeadBus synchronization
•
AutoSync – This tag follows the AutoSyncEn tag setting in the Scheduled
Write tag.
•
CheckSync - This tag follows the CheckSyncEn tag setting in the
Scheduled Write tag.
•
PermissiveSync - This tag follows the PermissiveSyncEn tag setting in the
Scheduled Write tag.
•
SyncFailure – This tag indicates that the synchronization attempt failed.
•
UndefinedSyncMode – This tag indicates that a synchronization was
initiated when none of the synchronization modes were asserted.
•
SyncModeConflict – This tag indicates that more than one
Synchronization mode was selected.
•
BusRot_ABC_ACB – This tag reports the rotation sequence of the
reference bus in three phase metering. In single phase metering, these bits
reflect the configuration value.
•
GenRot_ABC_ACB – This tag reports the rotation sequence of the
generator bus in three phase metering. In single phase metering, these bits
reflect the configuration value.
•
PhRotMatch – This tag reports that the phase rotation between the two
busses to be synchronized matches, and is acceptable for synchronizing.
•
V_Match - This tag reports that the voltage difference between the two
busses is within the configured acceptable range.
•
FreqMatch - This tag reports that the frequency difference between the
two busses is within the configured acceptable range.
