A 70-mi, single-circuit, three-phase line composed of Ostrich conductors k ar-ranged in flat horizontal spacing with 15 ft between adjacent conductors. The line delivers a load of 60 MW at 230 kV with 0.8 power-factor lagging. (a) Using a base of 230 kV, 100 MVA, determine the series impedance and the shunt admittance of the line in per unit. Assume a wire temperature of 50°C. Note that the base admittance must be the reciprocal of bast impedance. (b) Find the voltage, current, real and reactive power, and the power factor at the sending end in both per unit and absolute units. (c) What is the percent regulation of the line?
