Chapter 5, Problem 5.2P

A 200-km, 230-kV, 60-Hz, three-phase line has a positive-sequence series impedance $z=0.08+j0.48\Omega \text{/km}$ and a positive-sequence shunt admittance $y=j3.33\times {10}^{-6}\text{S/km}\text{.}$ At full load, the line delivers 250 MW at 0.99 p.f. lagging and at 220 k V. Using the nominal $\pi$ circuit, calculate: (a) the ABCD parameters, (b) the sending-end voltage and current, and (c) the percent voltage regulation.
