Synchronization Time Monitoring (With Synchronous Generators Only)
If the following parameter (Parameter 117) is configured to "ON", synchronization time monitoring is per-
formed: If the synchronization of the GCB or MCB [GCP-20/22] is initiated, the timer is started following the
termination of the delayed engine monitoring. If the breaker has not closed following the expiration of the con-
figured time, an F1 alarm message is issued.
NOTE
If during an enabled "MCB monitoring" (Parameter 130) an alarm is detected while closing the MCB, a
emergency power operation is performed (if this has been configured to ON;
Parameter 134).
Parameter 117
Sync.time contr.
ON
Monitoring of synchronization time ON/OFF
ON................ Synchronization time will be monitored. The subsequent screens of
this function are displayed.
OFF.............. Synchronization time will not be monitored. Synchronization will be
attempted until it can be accomplished. The subsequent screens of
this function are not displayed.
Parameter 118
Sync.time contr.
Delay time 000s
Final value for synchronization time monitoring 10 to 999 s
If the synchronization of the GCB or MCB is initiated, the timer is started follow-
ing the termination of the delayed engine monitoring. If the breaker cannot be
closed and this time has expired, an alarm message is issued and the control contin-
ues to attempt to close the breaker. The relay assigned relay manager func-
tion 16 (GCB) and/or 70 (MCB) is energized.
Issuing of class F1 alarm
Dead Bus Start (With Synchronous Generators Only)
If the busbar is de-energized, a dead bus start of the GCB or the MCB is performed. If closing commands for the
MCB and the GCB are issued simultaneously, priority is given to the MCB provided the discrete input "Enable
MCB" (terminal 54) has been enabled.
Parameter 119
GCB dead bus op.
ON
Dead bus start of the GCB ON/OFF
ON................ A dead bus start is performed in the event of a de-energized busbar
and an open MCB. The subsequent screens of this function are dis-
played.
OFF.............. A dead bus start is not performed. The subsequent screens of this
function are not displayed.
Parameter 120
GCB dead bus op.
df max 0.00Hz
Maximum differential frequency for GCB dead bus start 0.00 to 5.00 Hz
The prerequisite to issuing a close command is that the monitored generator fre-
quency may deviate from the generator rated frequency by no more than this value.
Parameter 121
GCB dead bus op.
dV max. 00V
Maximum differential voltage for GCB dead bus start [1] 1 to 20 V; [4] 2 to 60 V
The prerequisite to issuing a close command is that the monitored generator voltage
may deviate from the generator rated frequency by no more than this value.
