2) The effective resistance of a three-phase, 450 km long power transmission line is 0.06 2/km, its inductance Its capacitance is 5.039x10^-4 H/km and its capacitance is 3.349x10^-9 F/km. A symmetrical load group of 10-MVAr/phase with a power factor of 0.866 back under 71.59 kV phase-neutral voltage from the end of the power transmission line is fed. Considering this operating state of the line and the line parameters, a.) Find the line constants A, B, C and D of the power transmission line using hyperbolic functions. b.) Calculate the maximum power that the power transmission line can transmit. c.) Find the voltage regulation value of the energy transmission line and analyze the result.
