Homework Statement
Figure shows a 50 Hz, highvoltage, transmission line. The relationships between the sending and receiving end voltages and currents are given by the complex ABCD equations:
where 'S' stands for sendingend and 'R' stands for receivingend
(a) Given the parameter values in TABLE C and an opencircuit received voltage measured as 88.9 kV, calculate the values of
(b) If the line is modeled by the Tcircuit of FIGURE 3(b), see if you can estimate the primary line coefficients R, L, G and C. The line is 50 km long.
Homework Equations
The Attempt at a Solution
Regarding part b) this is what I have at the moment but not sure I am doing it correctly.
A= 0.8698+J0.03542 B= 47.94+J180.8 C= 0+J0.001349 D= 0.8698+J0.03542
This means that A and D a symmetrical A=D.
I don't really know where to go from here as I have looked at other posts on this question and they don't seem to make much sense due to lots of people asking several different questions.
