Fig. 3(b). 4. For the shown in Fig. 4(a) the generators are connected at the four buses, while the loads are at [5] buses 2 and 3. Values of real and reactive powers are listed in Table 4(b). All buses other than the slack are PQ type. Assuming a flat voltage start, find the voltages and bus angles at the three buses at the end of the first GS(Gauss-Seidel) iteration. 2-j6.0 1-j3.0 0.555-12.0 1-j3.0 3 2-j6.0 Fig. 4(a) Table 4(b): Bus data for Q. 3(b) Bus QL V₁₂ Remarks number p.u. p.u. 1 - 1.04 20° Slack bus Vi 1.040° 2 -0.2 -- PQ bus Let V₁"=120=V₁ = V₁ = V 3 -0.1 0.5 PQ bus For k=2,3,4, 4 0.3 -0.1 PQ bus A load of 12,000KW at a power factor of 0.8 lagging is supplied by a 3-phase line whose voltage 151 has to be maintained at (20+X)KV[Consider X is the last two digit of your student ID] at each end.
