Manual 26011Load Sharing ModuleFigure 4-2. Droop AdjustmentSetting Droop for an Infinite Bus1. With the generator not paralleled, adjust the speed above rated frequency bythe percent droop required (set engine at 63 Hz for 5 percent droop on a 60Hz system).2. Mark the speed setting potentiometer position or measure dc voltage onTB27(+) and TB26(–), and re-adjust the engine speed for rated frequency.3. Turn the DROOP potentiometer fully clockwise for maximum droop.4. Synchronize the generator with the bus and parallel it with the bus.5. Increase the speed setting potentiometer to the position marked in step 2,increasing load.6. Slowly adjust the DROOP potentiometer counterclockwise, decreasing droop,until 100 percent load is obtained.If it is necessary to set the droop without pulling 100 percent load, set the enginespeed accordingly for the desired percent of droop at the load to be pulled. Forexample: Five percent droop at 50 percent load will require a no load rated speedof 61.5 Hz, not 63 Hz, on a 60 Hz system.Woodward 21
