N**LOAD SETTINGS**
The Load Setting section is the set-up of the generator load control parameters.
01 KW LOAD DROOP % dflt = 5.000 (0.00
–12.00)
This is the percentage of rated speed the speed reference will droop when the
generator load (KW) is increased to maximum load. Set to the desired droop
percent.
02 LOAD LEVEL VOLTAGE dflt = 6.000 (0.10
–9.00)
Sets the voltage level of the load. The value of 6.0 is typical for most analog load
sharing schemes.
03 LOAD SHARE GAIN
dflt = 1.000 (0.01
–10.00)
Sets the load sharing gain. A too-high gain will result in unstable load sharing
between the units.
04 ENABLE ACT POS DROOP dflt = FALSE (TRUE, FALSE)
This enables the actuator position droop feature. Actuator position droop is a
feature that gives the control a speed droop percentage based on the actuator
position (fuel demand). This feature would be used if the control was not capable
of receiving a PT and CT signal for KW droop, or if for testing purposes.
05 ACT POSITION DROOP % dflt = 0.00 (0.00
–100.00)
The actuator dependant droop percentage setting, for proper droop control set
the below parameters 06 and 07 first. If load (kW) droop is used (GEN PT and
GEN CT are connected) set this parameter to 0.
