Question

1. In the power system network shown in Figure 1, Vi bus 1 is a slack bus with 1.00 per unit and bus 2 is a load bus with S2 Mvar. The line impedance on a base of 100 MVA is Z = 0.02 + j0.04 per unit (a) Using Gauss-Seidel method, determine V2 . Use an initial estimate of V=1.0j0.0 and perform four iterations (b) If after several iterations voltage at bus 2 converges to V2 = 0.90-j0.10, determine S1 and the real and reactive power loss in the line 280 MWj60 Z12 0.02 0.04 2 S2 280 MW 60 Mvar Figure 1.
