Confidence Analysis Method for Cable Distributed Parameter Model based on Verification & Validation

Abstract

An effective confidence analysis method for the cable distributed parameter model is proposed in this paper, while it is still a blank question at present. As the cable electromagnetic coupling model is composed of a transmission line model and a distributed parameter model, the proposed confidence analysis method takes two steps based on verification & validation (V&V) theory. One step is that confidence analysis of both models is completed by getting numerical calculation accuracy verified with numerical results and model accuracy validated with experiments results, to confirm the quantification of numerical calculation errors and model accuracy errors analysis. The other step is that the confidence analysis of the cable distributed parameter model must be established on the basis of that of the transmission line model. Such method is completed and confirmed with numerical and experimental examples in this paper. Further more, confirmed confidence of cable model leads to the validity of simulation data, which is an important mathematical foundation for simulation to produce practical results in cable layout engineering design and electromagnetic response evaluation.
