Abstract

A new algorithm for the calculation of the frequency-dependent parameters of arbitrarily shaped power cable arrangements is presented. The algorithm uses digitial images to discretize the cable geometry and the partial subconductor equivalent circuit method to estimate the cable parameters. The proposed methodology adapts itself to the physical memory of the computer, thus allowing the program to partition the partial subconductor impedance matrices when their sizes exceed the available physical memory. Coaxial cables and sector-shaped cables are studied, and the results are compared with those obtained from analytical formulae and the finite element method.
