HMI Navigation Path: Settings, Operating Settings, Gains, Other Gains
Settings for stability tuning of the Var and Power Factor modes are provided in the DECS-250 along with
settings for stability tuning of limiters, the voltage matching function, and main field voltage response.
Figure 102 illustrates these settings as they appear in BESTCOMS
Plus .

B
adjusts the coarse loop-gain level of the PI algorithm for var control.
Power Factor Mode
The integral gain (K
i
)
C
adjusts the integral gain which determines the characteristic of the DECS-250
dynamic response to a changed power factor setpoint.
The loop gain (K
