Question
24.) A 500 kV, 300 km 60 Hz three-phase overhead transmission line, assumed to be
lossless supply a load of 1000 MVA at o.8 power factor lagging and at 500 kV. It has
a series inductance of o.97 mH/km per phase and a shunt capacitance of o.0115
µF/km per phase. Determine the following:
A.) Zc (1.
В.) ВС
C. The capacitance/phase and total three-phase MVARS supplied by a three-
phase, A-connected shunt-capacitor bank at the receiving end to maintain the
receiving-end voltage at 500 kV when the sending end of the line is energized at 50o
kV. (, * )
