A d.c. serier generator, having an external characteristic which is a straight line through zero to 50 V 200 A is connected as a booster between a station bus bar and a feeder of 0.3 ohm resistane. Calculate the voltage difference between the station bus-bar and the far end of the feeder qa current of (i) 200 A and (ii) 50 A.

For the system as shown in the following figure, convert the components to same base voltage and apparent power, by choosing 100 kVA as the base kVA and 2000 V as the base voltage for the generators. Redraw the single line diagram with the new per unit values. 15 KVA 2000 V Z=j0.3 pu 25 KVA 2000 V Z=j0.15 pu G1 G2 35 KVA 2000/8000 V Z=j0.2 pu Z=30+j100 Z=60+j120 pu O pu leee 35 KVA 8000/2000 V Z=j0.3 pu 35 kVA 2000/8000 V Z=j0.25 pu G3 10 KVA 2000V Z=j0.35 pu M 30 KVA 2000 V
