ANSWER QUESTION 42 PLEASE.
***Line impedance between T4 and T5 is j25, not j2***
Extracted text: 3.42 For the power system in Problem 3.41, the synchronous motor absorbs 1500 MW at 0.8 power factor leading with the bus 3 voltage at 18 kV. 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.
Extracted text: 3.41 Consider the single-line diagram of the power system shown in Figure 3.38. Equipment ratings are Generator 1: 1000 MVA, 18 kV, X" = 0.2 per unit Generator 2: 1000 MVA, 18 kV, X" = 0.2 p.u. Synchronous motor 3: 1500 MVA, 20 kV, X" = 0.2 p.u. Three-phase A-Y transformers T1,T3, T3, Tạ: 1000 MVA, 500 kV Y/20 kV A, X = 0.1 p.u. Three-phase Y-Y transformer T3: 1500 MVA, 500 kV Y/20 kV Y, X = 0.1 p.u. Neglecting resistance, transformer phase shift, and magnetizing reac- tance, draw the equivalent reactance diagram. Use a base of 100 MVA and 500 kV for the 50-ohm line. Determine the per-unit reactances. FIGURE 3.38 2 Problems 3.41 j 50 N and 3.42 T2 T4 T3 | 25 2 T5 3)
