SYSTEM AND METHOD FOR PREDICTING PERFORMANCE OF ELECTRICAL POWER CABLES

摘要

A computer simulation method is disclosed for simulating an electrical cablehaving a stranded conductor surrounded by a conductor shield encased in aninsulation jacket and having an interstitial void volume in the region of theconductor injected with a fluid composition comprising at least one dielectricenhancement fluid component so as to at least partially fill the interstitialvoid volume at an initial time. The simulation method comprises for a selectedlength of the simulated cable, defining a plurality of radially arrangedfinite volumes extending the selected length of the simulated cable, andestimating the radial temperature of each finite volume. For a selected timeperiod after the initial time, performing a series of steps at least once andoutputting or otherwise using the value of the new concentration for thedielectric enhancement fluid component within each finite volume.
