    Solve this program

    Transmission lines are represented by an equivalent model with appropriate circuit parameters on a "per-phase" basis. They may also be represented by a two-port network.

    1) Write a function TLrlc2ABCD (r, l, g, f, length) which prompts the user for the TL parameters (r in ohms, l in mH and c in \muF per unit length and returns the transmission line matrix).
    2) Write a function TLzy2ABCD (z, y, length) which prompts the series impedance in ohms and shunt admittance in siemens per unit length and returns the transmission line matrix.
    3) Write a function TLPerfMenu () to prompt the user for the options available.

    To predict Transformer performamance, select option:
    1- Get TL matrix form TLr, l, c, g, length
    2- Get TL matrix from TLz, y, length
    3- Enter TL matrix eleme
    4- Exit​

    4) Use the above functions to compute the following:
    a. A 345-kV, three-phase transmission line is 130 km long. The resistance per phase is 0.036 \Omega per km and the inductance per phase is 0.8 mH per km. The shunt capacitance is 0.0112 \muF per km. The receiving end load is 270 MVA with 0.8 pf lagging at 325 kV. Use the pi model of the transmission line to compute the voltage and power at sending end , and the voltage regulation.

    b. A 345-kV, three-phase transmission line is 130 km long. The series impedance is z = 0.036 + jo.3 \Omega per phase per km, and the shunt admittance is y = j4.22x10-6 siemens per phase per km. The sending en voltage is 35 kV, and the sending end current is 400 A at 0.95 pf lagging. Use the pi model of the transmission line to compute the voltage, current and power at the receiving end, and the voltage regulation.

    lolo,
    Many of the regulars in this forum will be happy to help you, but only after you put some of your own efforts into it. Post the work that you have done and we'll guide you from there.
