Setting Droop for an Infinite Bus Load
1.
With the generator not paralleled, adjust the RATED SPEED potentiometer
on the EPG to give a speed setting above 60 Hz by the percent droop
required.
For example: Droop of 5% would require raising the speed to 63 Hz.
2.
Mark the potentiometer position and re-adjust the RATED SPEED
potentiometer for 60 Hz.
3.
Turn the DROOP potentiometer fully clockwise (for maximum droop).
4.
Open the OPEN FOR DROOP switch (or remove the wires from terminals
13 and 14).
5.
Synchronize the generator with the bus and parallel it with the bus.
6.
Return the RATED SPEED potentiometer to the mark made in step 2.
7.
Adjust the DROOP potentiometer counter-clockwise, decreasing droop, until
100% load is achieved.
This completes the calibration of the Load Sharing Module.
If it is necessary to set the droop without pulling 100% load, set the RATED
SPEED potentiometer (in step 1) accordingly for desired percent droop.
For example: at 5% droop, running at only 50% load, the RATED SPEED
potentiometer would be set at 61.5 Hz. in step 1.
