Modeling Approach for Transmission Lines in the Presence of Non-Fundamental Frequencies

This paper presents a transmission-line modeling tool to obtain a desired level of accuracy at non-fundamental frequencies. Specifically, the approach compares finitely segmented models to the uniformly distributed model in order to determine the appropriate segmentation of the line model for a desired frequency range. The line model performance is characterized through waveform propagation, including attenuation and phase shift. The software-based modeling tool is validated through hardware tests of different segmentations.
