Q.3: Two separately excited DC generators are connected in parallel to supply a total load
current of 200A. The two generators have the following parameters:
G1: Ra = 0.2 n , and induced E.M.F=400 V
G2: Ra = 0.5N , and induced E.M.F=460 V
Find Mathematically:
(i)The bus-bar voltage, The armature current of each generator,
(ii) The sharing power of each generator
(iii)If it's required to operate generator1 at maximum efficiency and at Vp
What is your opinion to achieve that? Resolve the problem.
bus-bar=400V.
