Abstract

This paper introduces a new frequency-dependent cable model for the simulation and analysis of electromagnetic transients. The model belongs to the traveling-wave class. The key feature of the proposed model is the correct representation of modal propagation function contributions in the phase domain. The challenge is in fitting modal contributions that are nonsmooth due to their eigenvectors. Since the nonsmooth behavior is associated with similar eigenvalues, the problem is solved by reducing the rank of the propagation matrix. The proposed new approach eliminates numerical instability problems that can be encountered in the universal line model.
