Short Transmission Line: Problem 1 (solving sending end voltage)

Short Transmission Line: Problem 1 (solving sending end voltage)
A 60 Hz short transmission line, having R = 0.62 ohms per phase and L = 93.24 millihenrys per phase, supplies a three-phase, wye connected 100 MW load of 0.9 lagging power factor at 215 kV line to line. Calculate (a) line impedance (b) line current (c) sending end voltage. ans (a) 0.62 + j35.15 ohms (b) 298.37 A (c) approx 223 kV
