Determining P line model parameters

[oblomof]

Dear friends!
I am implementing a distribution test system in MATLAB/SIMULINK. The conductor catalogue and tower characteristics are available. I would like model line by transmission line P-model. At first, capacitance, inductance and resistence matrix (that is 3*3 dimensions) hase been calculateed by SIMULINK powergui. How can I determine zero and positive sequences of capacitance,inductance and resistence to input p-model block?
Regards

See Paul Anderson Analysis of Faulted Power Systems. Also, most good Power System Analysis texts should describe the process of developing the sequence components. A hint would be that resistance and inductance are part of the same complex number and capacitance (admittance) is a whole separate calculation. The resistance/inductance matrix is itself a 3x3 matrix with the diagonal terms being the self impedances and the off diagonal terms being mutual impedances.
