Gain Effect on Generator Performance
When individual adjustment is needed to further refine performance, Figures 6-22 through 6-25
demonstrate the effect that PID changes have for additional control. These figures have a one second
major division.
In Figure 6-22, the generator voltage exhibits one under-damp (overshoot) and one over-damp
(undershoot) before settling. The total time (five seconds) is too long. Here KP (proportional gain) needs
to be increased.
Figure 6-19. Insufficient Proportional Gain
Figure 6-23 demonstrates that the terminal voltage has prolonged instability after a voltage step change
because there is too much integral gain (I). Integral gain value needs to be decreased.
