Question:
1. Two DC generators are connected in parallel
to supply a load of 1500 Amp. One
generator has an armature resistance of 0.5
and an emf 400 V, while the other has
an armature resistance of 0.04 ohm and an emf
of 440 V. The resistance of the shunt
field are 100 ohms and 80 ohms respectively.
Calculate the current I1 and 12
supplied by the individual generator and the
terminal voltage V of the combination.
2. Three shunt generators operating in parallel
supply a total load current of 2000 Amp.
Each machine has field resistance of 40 ohms
and an armature resistance of 0.02
ohm. The emfs generated are 240, 242, and
245 volts respectively. Determine the
current delivered by each generator.
