Rework Problems 5.9 and 5.16, neglecting the conductor resistance. Compare the results with and without losses.

Problem 5.9

The \(100-\mathrm{km}, 230-\mathrm{kV}, 60-\mathrm{Hz}\), three-phase line in Problems 4.18 and 4.39 delivers \(300 \mathrm{MVA}\) at \(218 \mathrm{kV}\) to the receiving end at full load. Using the nominal \(\pi\) circuit, calculate the \(A B C D\) parameters, sending-end voltage, and percent voltage regulation when the receiving-end power factor.

Problem 5.16

The \(500-\mathrm{kV}, 60-\mathrm{Hz}\), three-phase line in Problems 4.20 and 4.41 has a 300-km length. Calculate:

(a) \(Z_{c}\),

(b) \((\gamma l)\), 

(c) the exact \(A B C D\) parameters for this line. Assume a \(50^{\circ} \mathrm{C}\) conductor temperature.
