Question 1
a) Draw impedance diagram in per unit, by using 100-MVA base. Select 20kV as the
base voltage for generator section. Use parameter of equipment for the single
diagram shown in Figure 1, and specification as per Table 1. Assume the length of
transmission line is in the range of value in the table.

Motor Load
18 kV, 50 MW, power factor = 0.8 ~ 0.9
2
Transformer 2
200/20 kV, 50 MVA, X = 10%
Transmission Line
200 kV, Length = 4km - 15km, Z = 0.06 + j0.06 Q/m

Transformer 1
20/200 kV, 100 MVA, X = 5%
5
Generator 1
20 kV, 70 MVA, X = 9%
b) The motor is drawing 45 MVA with lagging power factor in the range of 0.8~0.9 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.
c) As an electrical engineer in one of the utility companies, you have been given a
single line diagram shown in Figure 2. Your specific task is to determine the phasor
values of the voltage at load buses 2 (P-Q buses) accurate to 4 decimal values
using Gauss-Siedel iteration up to three iterations in. Assume the power factor for
load at bus 2 is in the range of 0.85 ~ 0.95.
