The one line diagram of a three-phase power system is shown in
Fig.8. Impedances are marked in per unit on a 100 MW, 400 kV base.
The Load at Bus 2 is S2 = 15.93 MW - j33.4Mvar, and at Bus 3 is S3
= 77 MW + j14 Mvar. It is required to hold the voltage at Bus 3 at
400 kV, Angle 0 degs. Working in per unit, determine the voltages
at Buses 2 and 1.
