assignment time again transmission lines.

[Simon]

what I think I've managed most of this assignment on my own. I'm on the last part of the last question. I have been given an A B C D set of parameters for a power transmission line at 50 Hz. The power received or rather the voltage received is 88 . 9 KV and I am asked to work out sending voltage and power loss in the line which I have. The second part of the question tells me that the line is to be considered is made up of a succession of T type sections and that it is 50 km long. I am asked to find out the RGLC parameters.

Is this very difficult? Looking back through my course material I have at the beginning of the study of transmission lines a matrix formula that explains how to obtain the a B C D parameters knowing the impedances (I assume complex impedances)  of the 3 branches of the T network. Is there a way of reversing this or is it very complicated? This is kind of looking something like a simultaneous equation whereby I would find a set of primary coefficients that match the a B C D coefficients in the particular configuration. I have no idea if Microsoft Mathematica is capable of handling this sort of thing although it can do matrixes.
