A 400 km, 500kV transmission line has a series impedance of z = 0.015 + j0.175 2/km Shunt admittance is is y= j2.2 x 10-6 S/km. At full load, the line delivers 500MW at 475kV at 0.8power factor. Assume receiving voltage as reference, evaluate the performance of the line based on the following criteria: (i) Voltage drop (ii) (iii) (iv) the percent voltage regulation line losses the efficiency of the line A 400 km, 500kV transmission line has a series impedance of z = 0.015 + j0.175 2/km Shunt admittance is is y= j2.2 x 10-6 S/km.
