Description
Summary:This paper introduces a new frequency dependent cable model (FDCM) 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 phase domain. The challenge is in fitting modal contributions that are non-smooth due to their eigenvectors. As the non-smooth behaviour 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 (ULM).
