A three -phase, 60-Hz, 500 kV transmission line is 300 km long. The line inductance is 0.97 mH/km per phase and its capacitance is 0.0115 pFAm per phase. Assume a lossless line. a) Determine the line phase constant B, the surge impedance Ze; velocity of propagation o , and the wavelength A. b) The receiving end rated load is 800 MW, 0.8 power factor lagging at 500 kV. Determine the sending end: voltage, current, real power ,reactive power, power factor, and the voltage regulation. Calculate the receiving end voltage when the line is terminated by an open circuit and is energized with 500 kV at the sending end. (d) Determine the Mvar and reactance of a three-phase shunt reactor to be installed at the receiving end to keep the no-load receiving end voltage at the rated value of 500 kV, while the sending end voltage is kept at 500 kV.
