A 60 Hz, 230 mile, three-phase overhead transmission line has a series impedance of o.8431 cis(79.04°) N/mi and a shunt admittance y = 5.105 x 10-6 cis(90°) S/mi. The load at the receiving end is 125 MW at unity power factor and at 215 kV. Find the voltage regulation of the line. Simulate in Power World and show the voltage at full load and no load.

1 and 2 are connected. Number 1 is already posted in thus page. Please answer. Neglect the simulation thing. I only need the solution. 

1.) A 60 Hz, 230 mile, three-phase overhead transmission line has a series
impedance of o.8431 cis(79.04°) N/mi and a shunt admittance y =
5.105 x 10-6 cis(90°) S/mi. The load at the receiving end is 125 MW at
unity power factor and at 215 kV. Find the voltage regulation of the
line. Simulate in Power World and show the voltage at full load and no
load.

2.) Given the uncompensated line of #1, let a three-phase shunt reactor
(inductor) that compensates for (A) 70%; (B) 50%; and (C) 30% of the
total shunt admittance of the line be connected at the receiving end of
the line during no-load conditions. Determine the effect of voltage
regulation with the reactor connected at no load. Assume that the
reactor is removed under full-load conditions. Plot the graph of
compensation of shunt reactor and voltage at no load. Simulate also in
Power World.
