For the power system shown on the bottom left, the synchronous motor absorbs 1500 MW at 0.8 power factor leading with the bus 3 voltage at 18 kV. Equipment ratings are ... Generator 1: Generator 2: 1000 MVA, 18 kV, X" = 0.2 per unit 1000 MVA, 18 kV, X" = 0.2 pu Synchronous motor 3: 1500 MVA, 20 kV, X"= 0.2 pu Three-phase A-Y transformers T, T, T3, T4: 1000 MVA, 500 kV Y/20 kV A, X = 0.1 pu 1500 MVA, 500 kV Y/20 kV Y, X = 0.1 pu Three-phase Y-Y transformer T5: Neglecting resistance, transformer phase shift, and magnetizing reactance AND using a base of 100 MVA and 500 kV for the 50-ohm line, we drew the equivalent per-unit circuit diagram on the lower right. Determine the bus 1 and bus 2 voltages in 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. The per-unit equivalent circuit is shown on the right. YO 1 J 08 T T3 J 10380 25 (2 Y 3 150 PHOTO j2 (2 XX 2.
