Voltage control adjustment
1) Set
Voltage gain
,
Voltage int
to zero and
AVR DCout bias
to 50%.
2) Start always with AVRi pot min adjustment (fully counterclockwise).
3) Start the gen-set in MAN Mode to nominal speed, without load.
4) Adjust generator voltage to nominal value by the potentiometer present on the AVR. If there is no
potentiometer on the AVR, use
AVR DCout bias
to adjust the nominal voltage
.
5) Change
AVR DCout bias
to 0% and 100% to check generator voltage control range (typically
±
10
% of nominal voltage). Adjust voltage control range by AVRi trim.
6) Set
AVR DCout bias
to be Nominal voltage on generator (50%).
7) When gen-set is running unloaded increase carefully
Voltage gain
to unstable point and then
decrease value by 30 % to insure stable performance.
8) Adjust
Voltage int
(usually setting to 100% gives optimal performance).
Hint:
To judge optimal adjusting induce generator voltage jumps by
AVR DCout bias
change or by
Nominal
voltage
change .
AVRi output
OCOM
is common output. GND was used instead of OCOM
PF control adjustment
The genset should be cca 30 % loaded in parallel to mains and baseload mode.
1)
Set the same values
PF gain,
PF int
as in voltage control loop.
2) Set
Process control
:
#SysLdCtrl PtM
= BASELOAD, #Sys
BaseLoad
= 30 % of Nominal load,
#SysPFCtrl PtM
= BASEPF, #
SysPwrFactor
= 1.0.
3)
Start and synchronize the gen-set in MAN Mode by pressing GCB ON/OFF
4)
When running in parallel 30% loaded increase slowly
PF gain
to unstable point and then decrease
value by 30 % to insure stable performance.
5) Adjust
PF int
(usually setting to 100% gives optimal performance).
Hint:
To judge optimal adjusting induce generator power jumps by
SysBaseLoad
change or by soft changes of
AVR DCout bias
.
Force value
Force value 1-16
[ X ]
„Source“ setpoints containing the alternative values for selected „target“ setpoints. The setpoint with index X
corresponds to the ForceValueInXXth function.
