2. A 3-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 µF/km per phase. Assume the line is lossless. (a) Determine the lone phase constant ẞ, the surge impedance Zc, velocity of propagation v and the line wavelength 2λ. (12 points) (b) The receiving end rated load is 800 MW, 0.8 power factor lagging at 500 kV. Determine the sending-end quantities (Vs and Is), and the voltage regulation. (12 points)
