PSSE Line Prop

asked Oct 28 '16

I'm trying to verify the line constants for my short circuit model - I have 8 different substations and each T line has different length - When I model the structures in PSSE Line Prop, do I need to model all structures and set the circuit location in ft based on my reference substation or do I need to build the structure individually and get the R, X values for just that circuit.

The impedance of each circuit is different with all structures modeled vs individually. What's the correct way?

You have to model each corridor correctly,with the number of circuits in each section along the line route. This means that all circuits in each corridor shall be in the same Lineprop model.
