In Figure P16–61 the source and load busses are interconnected by a transmission line with ZW ¼ 70 þ j400 V=phase.

Theloadatbus2drawsanapparentpowerofjS2j ¼ 3MVAata lagging power factor of 0.85 and the line voltage at bus 2 is VL2 ¼ 230 kVðrmsÞ. Find the apparent power produced by the source at bus 1, the source power factor, and the line voltage at bus 1.
