Volt/PF ctrl
AVRRegChar
[ POSITIVE / NEGATIVE ]
Switch between AVR characteristic.
POSITIVE:
When the controller and AVRi output voltage increases – generator voltage increases.
NEGATIVE: When the controller and AVRi output voltage decreases – generator voltage increases.
Hint:
When set to NEGATIVE, Binary outputs AVR Up and AVR Dn still work without inversion.
Voltage gain
[ % ]
Gain of voltage control loop.
Step:
0,1 %
Range:
0,0 to +200,0 %
Voltage int
[ % ]
Relative integration factor of voltage control loop. Increasing of integration value causes quicker response.
Step:
1 %
Range:
0 – 100 %
Hint:
Voltage gain
and
Voltage int
setpoints are active (adjust AVR) when GCB is open to maintain the Nominal
voltage or to match voltage during synchronizing. Voltage loop operates as well in single island operation.
PF gain
[ % ]
Gain of power factor control loop.
Step:
0,1 %
Range:
0,0 – 200,0 %
PF int
[ % ]
Relative integration factor of power factor control loop. Increasing of integration value causes quicker
response.
Step:
1 %
Range:
0 – 100 %
Hint:
When any gain setpoint is set to zero, the corresponding control loop is switched OFF.
PF gain
and
PF int
setpoints are active only when the gen-set runs parallel to mains.
