2082 KartikChapter 6: Performance Analysis6.2 Voltage Regulation and Efficiency Calculation of Transmission Lines
A 3-phase, 50 Hz 100 km long overhead line has the following line constants: resistance per phase per km = $0.153\ \Omega$, inductance per phase per km = $1.21\ \mathrm{mH}$, Capacitance per phase per km = $0.00958\ \mu\mathrm{F}$. The line supplies a load of 20 MW at 0.9 power factor lagging at a line voltage of 110 kV at the receiving end. Calculate the regulation and efficiency.
