The Droop Curve
Droop is a straight line function, with a certain speed reference for every fuel
position. Normally a droop governor lowers the speed reference from 3% to 5%
of the reference, from no load to full load Thus, a 3% droop governor with a
reference speed of 1236 rpm at no load would have a reference speed of 1200
rpm at full load.
If the linkage is changed, altering the amount of governor output shaft travel from
no load to full load, the droop must be reset. Be sure to use a least 2/3 of the
governor output shaft travel to ensure stability and allow sufficient droop range
adjustment.
Uses Of Droop
Isolated Unit
Most governors are capable of operating in the isochronous mode, However,
droop operation is necessary for many applications.
