In Figure P16–64 the three buses are interconnected by transmission lines with wire impedances of ZW1 ¼

120 þ j800 V=phase and ZW2 ¼ 200 þ j1200 V=phase. The source at bus 2 produces an apparent power of jS2j ¼

400 kVA at a leading power factor of 0.9. The load at bus 3 draws an apparent power of jS3j ¼ 650 kVA at a lagging power factor of 0.95. The line current in line 2 is IL2 ¼ 3:25AðrmsÞ. Find the apparent power produced by the source at bus 1, the source power factor, and the line voltages at bus 1, bus 2, and bus 3.
