For the power system in Problem 3.41, the synchronous motor absorbs (1500 mathrm{MW}) at 0.8 power factor

Question:

For the power system in Problem 3.41, the synchronous motor absorbs \(1500 \mathrm{MW}\) at 0.8 power factor leading with the bus 3 voltage at \(18 \mathrm{kV}\). Determine the bus 1 and bus 2 voltages in \(\mathrm{kV}\). Assume that generators 1 and 2 deliver equal real powers and equal reactive powers. Also assume a balanced three-phase system with positive-sequence sources.
