Answer / sanu chaudhary

droop means speed regulation. if the machine is running at
1500 rpm at no load and the machine came on full load at
1545 rpm this means the droop of the governor is set 3%.so
if the both machine rating is equal hence droop should be
equaland if rating is diffrent ,droop should diffrent for
smooth operation of system .machine of higher rating should
have set less droop then other for equal load sharing

Answer / n.v.mani

Higher rated machine should be set at less droop than that
of lower rated machine,for equal load sharing and smooth
operation of system.If both machine ratings are equal,droop
should be equal.
