The serial impedance of the 300 km energy transmission line is 23 + j75 ohm / phase and the shunt admittance is j500 microSiemens / phase

The serial impedance of the 300 km energy transmission line is 23

+ j75 ohm / phase and the shunt admittance is j500 microSiemens / phase. A power of 50 MW with a power coefficient of 0.88 back under 220 kV interphase voltage from the end of the power transmission line is being shot. Using this data of the energy transmission line, a) Characteristic impedance of the energy transmission line, b) Natural apparent power of the energy transmission line according to the inter-phase operating voltage of 220 kV, c) The values ??of the A, B, C and D line parameters of the transmission line using hyperbolic functions, d) Calculate the maximum power that the energy transmission line can transmit.
