Example 4:
It is again desired to set the droop of the same generator set to 5%, but this
time the generator set cannot be run at 100% load. It has been decided to
run the generator set at 50% load, so the speed (in step 2) at which the
generator set is run would be 61.5 Hz. In step 7, the DROOP pot is then
turned counterclockwise only until the load is 50%.
Paralleled with Infinite Bus:
1. Run the generator set unloaded at rated speed.
2. Adjust the RATED SPEED pot to give a speed of:
Rated Speed -
3. Mark the position of the pot and return to rated speed.
4. Turn the DROOP pot fully clockwise (for maximum droop).
5. Synchronize the generator to, and parallel it with, the bus.
6. Return the RATED SPEED pot to the mark made in step 3.
7. Turn the DROOP pot counterclockwise (decreasing droop) until load is
100% (or the desired % of load).
