5) Increase
Load gain
to unstable load control and decrease value by 30 % to insure stable performance.
When
Load int
factor is set to zero gen-set load can differ from required Baseload.
6) To adjust and optimize
Load int
change several times
Base load
between 30 and 70 % of Nominal
power. Usually setting
Load int
to 100% gives optimal performance.
7) When gen-set is running full load check if
a. Speed governor output voltage value is not limited (not reached
SpeedGovLowLim
or
SpeedGovHiLim
)
b. Speed governor actuator isn’t mechanically limited or operates in small section of throttle range.

Mains
Exported active power is supplied to the mains. It is displayed in negative numbers e.g. –20kW.
Imported active power is consumed from the mains. It is displayed in positive numbers e.g. +20kW.
When reactive power is imported (>0) InteliMains-NT displays L (inductive) character of the load.
When reactive power is exported (<0) InteliMains-NT displays C (capacitive) character of the load.
Load
Active power consumed by Load is displayed in positive numbers e.g. 20kW.
When reactive power is positive (>0) InteliMains-NT displays L (inductive) character of the load.
When reactive power is negative (<0) InteliMains-NT displays C (capacitive) character of the load.
Genset
Generated active power is displayed in positive numbers e.g. 20kW.
When reactive power is positive (>0) IGS-NT displays L (inductive) character of the load.
When reactive power is negative (<0) IGS-NT displays C (capacitive) character of the load.
