Question:

Figure 3.32 shows the oneline diagram of a three-phase power system. By selecting a common base of 100 MVA and \(22 \mathrm{kV}\) on the generator side, draw an impedance diagram showing all impedances including the load impedance in per-unit. The data are given as follows:

Lines 1 and 2 have series reactances of 48.4 and \(65.43 \Omega\), respectively. At bus 4, the three-phase load absorbs 57 MVA at \(10.45 \mathrm{kV}\) and 0.6 power factor lagging.
