Fig Qshows the one-line diagram of a three-phase power system.
As shown in Fig. Q3. the two zones are connected by a 400 MVA,
240-kV/24-kV, Ý-A three phase transformer. The Y-A three phase
transfonmer has an equivalent series impedance of ZTH - 1.2 + j1.6n
per phase referred to the high voltage side (primary side). The
three-phase power system can be studied with per unit quantities
using base values of S-500 MVA and 240 kV in zone 1.

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.
