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: Yes
Hint:
If you want to lock out the GCB closing during synchronizing loop test, set Phase window = 0. This allows the
control loop to be tested while actual GCB closing is blocked.
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: 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: Yes
Angle gain [ % ]
Gain of angle control loop.
Step: 0,1%
Range: 0,0 % to +200,0 %
Speed gov bias [ V ] (FV)
Speed control DC output bias level of SPEED GOVERNOR voltage output.
