A New Method to Cable Performance Assessment

Abstract:

This paper presents a new approach to thermal field sensitivities and ampacity computations of underground power cables using a proposed algorithm of perturbed finite-element analysis. Domain-specific visual language tools have become important in many domains of software engineering and end user development. Numerical results show that the most significant randomness comes from thermal loads and also that the amount of uncertainty decreases from input to output. We will show that the object-oriented programming greatly simplifies the choice and the implementation of other formalisms concerning polyarticulated systems, thus conferring high flexibility and adaptability to the developed software.Such experimental verification confirmed the accuracy of the new introduced finite-element sensitivity methodology.
