PROBLEM: A 230-kV, 50 Hz, three-phase transmission line is 120 km long. The line has a per phase series impedance of z-0.05 +j0.45 Ω per km, and a per phase shunt admittance of y 3.4x10-6 Siemens per km. The line delivers (at the receiving end) 200 MVA, 0.8 lagging power factor at 220 kV. Now consider two cases: A- Assume that shunt parameters of the transmission line are ignored (i.e. even if this is a medium length transmission line, under...

power system
A single-circuit 60-Hz high voltage power transmission line is 370 km (230 mi) long. The conductors are Rook with flat horizontal configuration and 7.25 ms=(23.8 ft.) conductor spacing. The load on the line is 125 MW at 100% power factor. Use attached Tables A3 to A3to determine; The sending end voltage Vs The sending end current Is The sending end power Ps The percentage voltage regulation The transmission efficiency Given that Ds for the Rook conductor is 0.0327...
