Question
Q2. Figure Q2 shows the single-line diagram. The scheduled loads at buses 2 and 3 are as
marked on the diagram. Line impedances are marked in per unit on 100 MVA base and the line
charging susceptances are neglected.
a) Using Gauss-Seidel Method, determine the phasor values of the voltage at load bus 2
and 3 according to second iteration results.
b) Find slack bus real and reactive power according to second iteration results.
c) Determine line flows and line losses according to second iteration results.
d) Construct a power flow according to second iteration results.
