Phase-Domain Line/Cable Model<?Pub _newline ?> Through Second-Order Blocks.

This paper introduces a new realization for a phase-domain line model and proposes methodologies to increase its numerical performance. The new realization is based on the management of complex poles that may arise when deriving rational models by means of second-order states. The accuracy and numerical performance of the proposed realization is assessed through its application to representative examples and the comparison against other methodologies. It is demonstrated that the proposed methodology can increase substantially the numerical efficiency of the model. [ABSTRACT FROM PUBLISHER]
