AC Machines

Two star-connected generators are connected in a parallel and supply a balanced load of 1500kva at 11kV line voltage and 0.8lagging power factor. The Synchronous reactnces of the two machines respectively are: 35 ohms and 40 ohms. The prime mover governors of the two machines are adjusted so as to equally share the power load The phase current in one machine is 43A at a lagging power factor Calculate:

a) The phase current in the second machine

b) The induced emf of each machine

c) The power factor at which each machine operates.
