help on this question about medium transmission line?

 

A three-phase, 60-Hz, completely transposed 440-kV, 120-km line has two conductors per bundle and the following positive-sequence line constants:

z = 0.085 + j 0.42 Ω/km                                      y = j4.2*10^-6 S/km

Full load at the receiving end of the line is 500 MW at 0.94 p.f. lagging and at 92% of rated voltage. Assuming a medium-length line, determine the following:

a) ABCD parameters of the nominal π circuit

b) Sending-end voltage VS and current IS
