A three-phase 50 Hz transmission line with a length of 30 km supplies a load connected to the receiving end. The line resistance is
0.07??km?
per phase and the line inductance is
1.0m(H)/(k)m
per phase. Load data is given as:
4MVA,34.5
kV , and 0.9 power factor lagging. Using the short line model, compute the followings: a) ABCD parameters ( 5 p ) b) The sending voltage and current (10 p) c) The sending end complex power and power factor (5 p) d) Total real and reactive power loss in the line ( 5 p ) e) Voltage regulation and the efficiency of the line (5 p)
