A 30-km, 34.5-kV, 60-Hz three-phase line has a positive-sequence series impedance z = 0.19 + j0.34 ?/km. The load at the receiving end absorbs 10 MVA at 33 kV. Assuming a short line, calculate:
(a) ABCD parameters,
(b) the sending-end voltage for load factor of 0.9 lagging,
(c) the sending-end voltage for load factor of 0.9 leading.
