16–64 In Figure P16–64, the three buses are interconnected by transmission lines with wire impedances of ZW1 = 100 +

j600 Ω=phase and ZW2 = 120 + j800 Ω=phase. The source at bus 2 produces an apparent power of j S2 j = 300 kVA at a lagging power factor of 0:85. The load at bus 3 draws an apparent power of j S3 j = 600 kVA at a lagging power factor of 0:8. The line voltage at bus 3 is VL3 = 161 kV

ðrmsÞ. Find the apparent power produced by the source at bus 1, the source power factor, and the line voltages at bus 1 and bus 2.
