Sequential computation of transfer function dominant poles of s-domain system models

Summary form only given. This paper describes an algorithm for the sequential computation of transfer function dominant poles of s-domain system models. The algorithm is suited for the modal analysis of high frequency dynamics of electrical networks having distributed parameter transmission lines. Results on a 39-bus electrical network containing 34 transmission lines are described to show the potential application of the proposed algorithm to infinite systems. The results clearly demonstrate the computational efficiency and numerical robustness of the algorithm, which is quite general and may be applied to s-domain system models that appear in other areas of engineering.
