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.
