working of a diesel generator.
Answer Posted / vijayanand bhuvad
Diesel Generator (D.G.) is the combination of Diesel Engine
& Alternator.
1. Engine works as a primover of alternator .Engine &
Alternator shafts are couplled. Thus mechanical energy
generated by diesel engine is converted in to Electrical
Energy using Alternator as Ferads 2nd Law of
Electromagnetic Induction.
2. Engine speed is set as per Alternator synchronous speed
by consedaring required frequency of AC supply.
3. For frequency control Governer, Governer control
card,Solid State potentiometer is used due to which Engine
speed is maintained.
1A. Generaly fixed armature & rotating field arrengement is
used to avoide sparking on sleepring.
2A. Field pols (as per Synchronous speed-:
P=120F/N),Exciter & Rotating rectifer assembly is fixed on
Alternator shaft.
3A. A.V.R. (automatic voltage regulator) is used to
regulate terminal voltage of alternator. Two phases &
neutral is connected for feedback to AVR. F1 & F2 of AVR
asr connected to field of exciter.
4A. Generated ac voltage in exciter is rectified through
Rotary Rectifier Assembly and supplied to Main Field of
Alternator.
