¿µ¹®³»¿ë¿ä¾à A circuitary model is shown to reflect quantitatively the relationship of mutual impedances between multiple parallelized conductors following a railway and a matrix form is provided to calculate a total inducing current pertinent to a certain devided section of those parallelized lines.
A matrix form for impedances between the lines which is needed to calculate this total inducing current is provided and a coalesced equation of matrix forms to calculate potential vectors corresponding to a selected line section.
In addition, calculating equations for the admittances between the lines are described and calculation methods of current source vectors fed from a origin point of power plant system are provided.
The major related matrices of impedance and admittance which are pertinent to a real alternate current electrified railway are provided in the Annex.
