Two 3-phase, 6.6kW, star-connected alternators supply a load of 300kW at 0.8 pf lagging. The synchronous impedance per phase of machine A is (0.5+j10) ohm and of machine B is (0.4+j12) ohm. The excitation of machine A is adjusted so that it delivers 150A at a lagging power factor and the governors are so set that load is shared equally between the machines. Determine the current, power factor, linduced emt, and load angle of each machine.
