A 225 km long transmission line has the following parameters: R=0.1 ohm/km, L=1mH/km, C=0.01uF/km. The line feeds a 100MVA load at power factor 0.9 lagging at a voltage of 275kV. Calculate: i. The A, B, C, D constants of the line. ii. The characteristic impedance of the line. iii. The sending-end voltage iv. The sending-end current. v. The sending-end power factor. vi. The sending-end power. vii. The power loss in the line. viii. The transmission line efficiency. ix. The percentage of voltage regulation.
