6. For a three bus power system assume bus 1 is the swing with a per unit voltage of 1.020 , bus 2 is a PQ bus with a per unit load of 2.0 + j0:5, and bus 3 is a PV bus with 1.0 per unit generation and a 1.0 voltage setpoint. The per unit line impedances are j0.1 between buses 1 and 2, j0.4 between buses 1 and 3, and j0.2 between buses 2 and 3. Using a flat start, use the Newton-Raphson approach to determine the first iteration phasor voltages at buses 2 and 3.
A 3-phase generator has positive, negative, and zero-sequence reactance's of 0.30, 0.20, and 0.05 p.u. respectively. The generator is connected to a three-phase transformer Delta-Wye grounded with positive and negative sequence reactance of 0.10 p.u. and zero sequence reactance equal to 0.20 p.u. The transformer is connected to a transmission line having positive and negative sequence reactance of 10% and a zero-sequence reactance of 35%. The transmission line is connected to another Wye-Delta transformer and then to a three-phase load with each branch impedance being j1.0 and the neutral is grounded through a reactance of j1.0.
