Two three-phase, 6.6-kV, wye-connected synchronous generators, operating in parallel, supply a load of 3000 kWat 0.8 power factor lagging. The synchronous impedance per phase ofmachine A is 0.5 + j10 , and of machine B it is 0.4 + j12. The excitation of machine A is adjusted so that it delivers 150 A at a lagging power factor, and the governors are set such that the load is shared equally between the two machines. Determine the armature current, power factor, excitation voltage, and power angle of each machine.
