Two alternators A and B operate in parallel and supply a load of 15MW at 0.5 power factor lagging. a) By adjusting steam supply of Alternator A, its power output is adjusted to 6MW and by changing its excitation, its power factor is adjusted to 85% lagging. Find the power factor of Alternator B. b) If steam supply of both machines is left unchanged, but excitation of Alternator B is reduced so that its power factor becomes 85% leading. Find the new power factor of Alternator A.
