HYPERSIM LINE
The “Hypersim Line” window also allows you to download parameters into Hypersim Line models.
Apply the parameters to the Hypersim Line models that you have selected.
the computed data. It can then be loaded onto the line. This tab will be fulfilled once the electrical parameters computation.
The displayed electrical parameters are:
R matrix, L matrix, and C matrix parameters.
TI tranformation matrix.
R, L, and C vectors of values for modal parameters.
R, L, and C vectors of self-impedance values are displayed for zero & positive sequence parameters.
R, L, and C vectors for mutual impedance values between lines are displayed for mutual zero-sequence.
The R, L, C parameters are always displayed respectively in ohms/km, henries/km, and farads/km
Example of a 735-kV three-phase line transposed.
Check the figure 7.1 for the geometrical parameters of the line and 7.3 for the layout of conductor.
