A factory load of 900 kW at 0.6 power factor lagging is to be increased by the addition of a synchronous motor that takes 450 kW. At what power factor must this motor operate, and what must be its kilovoltampere input if the overall power factor is to be 0.9 lagging?

14.45      A non–salient pole, Y-connected, three-phase, two-pole synchronous generator is connected to a 400-V (line to line), 60-Hz, three-phase line. The

stator impedance is 0.5 + j1.(per phase). The generator is delivering rated current (36 A) at unity power factor to the line. Determine the power   angle

for this load and the value of Efor this condition. Sketch the phasor diagram, showing EbI, and V.
