Setpoint: Angle Gain

Description
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
. The angle
regulation loop is active in this step.
As soon as the phase angle difference stays within the window adjusted by
and the voltage difference stays in the
, both
for period
, the circuit breaker closing command is issued.

Setpoint: Sync timeout

Description
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.
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.
