WARE pany of America) 30 Points 2- The one-line diagram of a three-phase power system is shown in Figure 2. The transformer reactance is 20 percent on a base of 100-MVA, 23/115-kV and the line impedance is Z=j66.125. The load at bus 2 is S₂ 184.8 MW+j 6.6 Mvar, and at bus 3 is S3 = 0 MW + j 20 Mvar. It is required to hold the voltage at bus 3 at 115 kV. Working in per unit, determine the voltage at buses 2 and 1. V₁- "I V₂ S2 166.125 Ω V3 Figure 2 One-line diagram for problem 2 S3
