sir branch resistance and reactance are given please tell how to get rmatrix,xmatrix and cmatrix so that i can write line code.i am creating 69 bus distribution system
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
It shows how to calculate the matrices from the geometry and the electrical parameters data of your conductors. It also shows how to specify both in OpenDSS using linegeometry and wiredata objects and let OpenDSS do the calculation for you.

Actually my doubt is that in my data only series resistance and reactance
are given so with how can I write linecode making r and x matrix,I have
seen that video what you suggested but still facing problem length is also
not given

Then I suppose you are dealing with a positive sequence dataset. In this case you could use R1, X1 parameters to define your lines. As for the length, simply set it to 1 and the model will be created assuming the values set in R1, X1 directly.

Your data looks like it omits C1. If you want it to be zero, set it explicitly (C1=0). Otherwise there is a default value that may not be what you want.
Time to learn about transmission line modeling!

Hi vaibhavi,
Please check the following video: https://www.youtube.com/watch?v=s8c9xq8IxUQ&list=PLcOap2oqW_gEMEVH9dg2HoXJ4NvydfsZM&index=9
