Question:

A $30-\mathrm{km}, 34.5-\mathrm{kV}, 60-\mathrm{Hz}$, three-phase line has a positive-sequence series impedance $z=0.19+j 0.34 \Omega / \mathrm{km}$. The load at the receiving end absorbs 10 MVA at $33 \mathrm{kV}$. Assuming a short line, calculate:

(a) the $A B C D$ parameters,

(b) the sending-end voltage for a load power factor of 0.9 lagging,

(c) the sending-end voltage for a load power factor of 0.9 leading.
