A three-phase, 380-kV, 60-Hz, OHTL has a configuration as shown in the following figure, is composed of two ACSR, 72/7 kiwi conductor/phase, The line is 300 km long, Using the proper Matlab programs to answer the following questions: Resistance per phase per km at 50oC; Inductance and capacitance per phase per km; Line current-carrying capacity (Ampacity); The impedance which makes the voltage along the transmission line nearly the same if the line is terminated with this impedance; Propagation constant; Wavelength The surge impedance loading SIL; ABCD Constants. The transmission line is energized with 380 kV at the sending end when the load at the receiving end is removed.

(a) Find the receiving end voltage (b) Determine the reactance and the Mvar of a three-phase shunt reactor to be installed at the receiving end in order to limit the no-load receiving end voltage to 380 kV. (c) Obtain the voltage profile for the uncompensated and the compensated line with explanation. Obtain the line loadability curves when the sending end voltage is 380 kV, and the receiving end voltage is 320 kV. Hint: The current-carrying capacity of the line is obtained from part (3), you should multiply this value by the number of acsr conductors
