Detailed CGCM Unit Tag Descriptions Appendix E
• CheckSyncEn – This tag is used to configure the CGCM unit to perform
Check Synchronization. This is one of three synchronization modes, each
selected by their respective tag. Only one can be active (1) or the
SyncModeConflict tag is activated and the synchronization fails (indicated
by SyncFailure tag).
• PermissiveSyncEn – This tag is used to configure the CGCM unit to
perform Permissive Synchronization. This is one of three synchronization
modes, each selected by their respective tag. Only one can be active (1) or
the SyncModeConflict tag is activated and the synchronization fails
(indicated by SyncFailure tag).
• InitiateSync – Setting this tag causes the CGCM unit to begin a
synchronization sequence. This bit must stay set throughout the
synchronization or the sequence is terminated.
• SyncFreqHiLim – This tag sets the upper limit frequency (in Hz) that is
considered acceptable for a synchronization of two busses.
• SyncFreqLoLim – This tag sets the lower limit frequency (in Hz) hat is
considered acceptable for a synchronization of two busses.
• SyncV_HiLim - This tag sets the upper limit voltage (in percentage) that
is considered acceptable for a synchronization of two busses.
• SyncV_LoLim - This tag sets the lower limit voltage (in percentage) that is
considered acceptable for a synchronization of two busses.
• SyncPhHiLim - This tag sets the upper limit phase (in degrees) that is
considered acceptable for a synchronization of two busses.
• SyncPhLoLim - This tag sets the lower limit phase (in degrees) that is
considered acceptable for a synchronization of two busses.
• SyncAcceptDly - This tag configures the time delay that is required to
allow for breaker closing. This setting is based on the time the frequency,
voltage and phase angle of the generator, and bus have been matched.
• BusRotABC_ACB_Select – This tag is used to configure the reference
bus rotation sequence.
• GenRotABC_ACB_Select – This tag is used to configure the generator
bus rotation sequence.
• DeadBusGenFreqLoLim - This tag configures the minimum frequency
that must be present on the generator to allow the breaker to close under a
Dead Bus condition.
• DeadBusGenFreqHiLim - This tag configures the maximum frequency
that must be present on the generator to allow the breaker to close under a
Dead Bus condition.
• DeadBusGenV_LoLim - This tag configures the minimum voltage that
must be present on the generator to allow the breaker to close under a
Dead Bus condition.
• DeadBusGenV_HiLim - This tag configures the maximum voltage that
must be present on the generator to allow the breaker to close under a
Dead Bus condition.
• DeadBusClosureEn – Setting this tag to 1 lets the generator achieve
breaker closure with a dead bus.
