See the system below. The power base is selected to be 100MVA and the rated line to line voltage of the transmission system is below. The parameter of the transmission line from Bus2 to Bus3 is given as follows: 500km, three-phase overhead transposed transmission line with a series impedance 0.8431279.04°/km and a shunt admittance y = 5.105 x 10-6290° S/km. B1 B2 B3 B4 T1 Transmission line 500km T2 L1 G1 #+ 40MW +j10Mvar 100MVA 69kV/500kV 60MVA 150MVA 500kV/69kV Z=j0.15 Z=jo.2 Y-Y Connection Y-Y Connection (d) Assuming the flat start, use Newton-Raphson method to solve the power flow for this problem and you only need to do the first full iteration and calculate up to x(¹) and x(²).
