12.2.9.7 Setpoint: Angle Gain
This setpoint is used for adjusting of the gain factor (P-factor) of the phase
angle P-control loop.
The synchronizing process contains two following steps:
1. The first step is to match the busR frequency to the busL frequency.
2. The following step is to match the phase angle difference of the busR
and busL voltages to the setpoint BRtoBLAngleReq. The angle
regulation loop is active in this step.
As soon as the phase angle difference stays within the window adjusted by
Phase window and the voltage difference stays in the Voltage window, both
for period Dwell time, the circuit breaker closing command is issued.
NOTE:
See the chapter Regulation loops overview for general information about
regulation loops and their adjustment.
12.2.9.8 Setpoint: Sync timeout
1 .. 1800, NO TIMEOUT [s]
This setpoint adjusts the maximum duration of synchronization. If the
synchronizing is not successful within this period of time, the Sync Timeout
alarm will be issued.
NOTE:
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.
