Hi,
I modelling double circuit line with Distributed Parameter Line. I have positive and zero sequence impedance of line and mutual impedance of lines. How to enter this data to block parameters? I think this block six=phase, but I don't know how need to form matrices of line parameters. Do you have examples?

Hello,
You only have to use a matrix if the line is asymmetric.
The documentation for the Distributed Parameter Line block mentions this:
For a symmetrical line, you can either specify the N-by-N matrix or the sequence parameters. For a two-phase or three-phase continuously transposed line, you can enter the positive and zero-sequence resistances [r1 r0] . For a symmetrical six-phase line you can enter the sequence parameters plus the zero-sequence mutual resistance [r1 r0 r0m].
If your line is asymmetric, you can double-click the Powergui block in your model and select Compute RLC Line Parameters . This can help you get matrices and push them into a block, although I think the information you have is more compatible with the [r1 r0 r0m] block entries.
Best,
Sebastian

Thanks for answer!
I did so, but calcCurrent not equal ControlCurrent. In standard examples of Simulink I find example of calculation parameters of Double-Circuit Line 315 kV. Result matrice of resistance have size 6x6, result matrice of sequence parameters have size 1x5. When I enter this parameters in block I have error "Attempted to access z(1,6); index out of bounds because size(z)=[1,5]".
