While at the same time increasing fuel to compensate for additional load. It permits a stable division of load between two prime mover electricity or mechanically connected to common services. number of engines delivering power to a common shaft or bus bar). Speed droop is defined as the difference in revolutions per minute from the equilibrium revolutions at no load on the engine to that at full load .It is expressed as a percentage of a maximum rated speed.
Droop is specially provided to stabilize the governor function. If droop is not provided, the governor becomes too sensitive and the governor hunts resulting in speed fluctuation.
