11.2.10.13 Setpoint: Sync timeout
Group Sync/Load Ctrl
Range [units] 1 .. 1800, NO TIMEOUT [s]
Related FW standard v3.1.0
Description This setpoint adjusts the maximum duration of forward or reverse
synchronization. If the synchronizing is not successful within this period of
time, the
Sync Timeout or RevSyncTimeout alarm will be issued.
N
OTE
:
If the synchronizing is not successful within 1/10 of the Sync timeout or 60s
(if Sync timeout <600s) the synchronization process is automatically restarted
again, i.e. the speed governor output is reset to bias value in gen-set
controllers and then frequency regulation loop is started again. If NO
TIMEOUT is selected the automatic restart occurs every 180s. This method
helps to sychronize successfully even in difficult conditions.
