Parametric transient thermo-electrical PSPICE model for a power cable

Abstract

A parametric transient thermo-electrical coupled PSPICE macro model for a power cable as well as the verification results of the experimental and finite element simulation will be introduced. The paper describes the modeling and simulation of a simplified, single-core cable parametric model, for the use in a circuit simulator e.g. PSPICE. The verification of the simulation data between ANSYS and PSPICE has shown good results. The results of comparison between PSPICE and the experimental data are suitable. With the introduced PSPICE cable model it is now possible to model quickly at system level under various thermal conditions and cable geometries and to have time saving transient thermo-electrical simulation results to overlook the thermal influences and temperatures along the power cable and to optimize e.g. the size, weight (copper diameter, used insulating material) of the power cable under real `thermal' assembling conditions in a e.g. car or truck.
