Answer Posted / p.viswanath rao
Diesel Generator is a set of engine and alternator.
(Which converts mechanical energy in to electrical energy)
here engine is using for rotating the shaft(prim mover or
crank shaft).
Rotation takes place as fallows:
1)The pistons placed in cylinders and these pistons are
connected to Crank shaft through connecting rads
2)By using diesel as a fuel the blasting takes place in
cylinders, this blasting energy can be converted in to
rotation through piston,connecting and crank shaft
3)this rotor speed strength(should be synchronous
speed)depends on firing order of the cylinders (of course on
number of poles on rotor)
4)this shaft is connected to Alternator rotor
5)this rotor contains poles, this rotor will get the D.C
supply from A.V.R through Exciter (RRA: Rotating Rectifier
assembly, it is a converter bridge)
6)So with rotor(poles) rotation the EMF will induce in main
Stator(Faraday's law of electro magnetic effect)
7)A.V.R out put depends on load effect on D.G.
