Compensator coefficient diagram:
Example with a compensation factor of 0.5
Controller time delay P148 = 100 seconds
Compensation time = 10 seconds
A: 1st compensation result. The controller‟s remaining time is
(100 - 10 = 90 seconds) × 0.5 = 45 seconds.
B: 2nd compensation result. The controller‟s remaining time is
(45 - 10 = 35 seconds) × 0.5 = 17.5 seconds
C: 3rd compensation result. The controller‟s remaining time is
(17.5 - 10 = 7.5 seconds) × 0.5 = 3.75 seconds.
R = 0: Moment when the controller‟s time delay = 0.
The two time delays are resynchronised at this moment.
