Phase window
[
°
] (FV)
Maximum phase angle (mains/bus x generator voltage)
±
difference between requested and actual angle for
synchronizing.
Step:
1
°
Range:
0
°
– 90
°
Force value possibility: Yes
Hint:
If you want to lock out the GCB (or MCB) closing during synchronizing loop test, set
Phase window
= 0. This
allows the control loop to be tested while actual GCB (or MCB) closing is blocked.
If force value function is used with this setpoint, it is strongly recommended to use only another setpoint as
the source of an alternative value (preferably from group Force value). Measured values are not optimal for
this purpose.
Dwell time
[ s ] (FV)
The period of time that the phase angle must be within
Phase window
and voltage differece within
Voltage
window
before a breaker (GCB/MCB) is closed.
Step:
0,1 s
Range:
0,0 – 25,0 s
Force value possibility: Yes
Freq gain
[ % ]
Gain of frequency control loop.
Step:
0,1 %
Range:
0,0 % - 200,0 %
Freq int
[ % ]
Relative integration factor of frequency control loop.
Step:
1 %
Range:
0 % – 100 %
Freq reg loop
[ GCB OPEN / SYNC ONLY ] (FV)
GCB OPEN:
Frequency control is active during running unloaded period and during synchronizing.
SYNC ONLY:
Frequency control is active during synchronizing only.
Force value possibility: Yes
Angle gain
[ % ]
Gain of angle control loop.
Step:
0,1%
Range:
0,0 % to +200,0 %
