3.15. The three-phase power and line-line ratings of the electric power system shown in Figure 3.34 are given below. (a) Draw an impedance diagram showing all impedances in per-unit on

a 100-MVA base. Choose 20 kV as the voltage base for generator. (b) The motor is drawing 45 MVA, 0.80 power factor lagging at a line-to-line terminal voltage of 18 kV. Determine the terminal voltage and the internal emf of the generator in per-unit and in kV.
