PI Section, 6-ph

Description

The PI line model is mainly used for short transmission lines. The equivalent circuit is shown below.

It is assumed that the capacitance on both sides is identical. The RL branches are also coupled. The parameters for the 6-phase PI lines are the same as for those for 3-phase PI lines, except that the dimension of the R, L, and C matrices representing the impedance and admittance of the conductors is 6x6, instead of 3x3. The reason is that this model represents a line with six conductors. A 6-phase PI model can be used to represent a double-circuit transmission line. The neutral coupling between both circuits (mutual impedance) is represented only in zero sequences.
