Data of a 3-phase WB Line Model
The following figure shows the geometrical data of a 735-kV transmission line as an example to simulate a 3-phase WB model.
The calculation of the electrical parameters can be done with the Line Data auxiliary module. The lyz file is used in the Wideband Line/Cable Fitter module to produce a dat file for the WB line model. A portion of the dat file generated with the Wideband Line/Cable Fitter is shown next.
