Electrical Engineering

A 60-Hz, 230-km, three phase overhead transmission line has aseries impedance z = 0.85<78.04 ̊ /km and a shunt admittance y= 5.105 x 10-6 < 90 ̊ S/km. The load at the receiving end is 135MW at unity power factor and 215 kV. Determine the voltage,current, real and reactive power at the sending end and the percentvoltage regulation of the line.
