1. A 230-kV, three-phase transmission line has a per phase series impedance of z = and a per phase shunt admittance of y = j3/4 × 10–6 siemens per km. The line is 80 km long. Using the medium length model, we want to evaluate the transmission line efficiency when the line delivers 200 MVA, 0.8 lagging power factor at 220 kV. Determine 0.05+ j0.45 N per Km (a) the transmission line ABCD constants. (b) the sending end voltage and current, (c) the voltage regulation, (d) the sending end power
