10-7. Figure P10-2 shows a one-line diagram of a three-phase power system. The ratings of the various components in the system are: 40 MVA, 13.8 kV, R = 3%, X Synchronous Generator 1: 20 MVA, 13.8 kV, R = 3%, X Synchronous Motor 2: 10 MVA, 13.2 kV, R = 3%, X Synchronous Motor 3: =80% 80% =100% Y-A Transformers: 20 MVA, 13.8/138 kV, R= 2%, X= 10% Line 1 Line 2 Line 3 The per-unit system base for this power system is 40 MVA, 128 kV in transmission line 1. Create the per-phase, per-unit equivalent circuit for this power system. R= 10 Ω, X = 50 Ω R=5 Ω,X = 30 Ω R=5 Ω, X= 30 Ω L Region 2 AY Region 3 Region L Region 4 Region 5 YA Bus 1 Bus 2 Ts Bus 3 Region 6 Calculate the bus admittance matrix Y 10-8 and the bus impedance matrix Zis for the power bus 00 system shown in Figure problem 1.
