要約(日本語): Modeling power cable systems is possible by means of the classical approach using closed-form approximations or numerical techniques such as the finite-element method (FEM) or the Method-of-Moments (MoM). The classical approach has been successfully applied to electromagnetic transient (EMT) studies in EMT-type programs for modeling conventional cables such as coaxial or pipe-type cables. However, cables with more complex cross-sectional areas are gradually appearing in practical systems as designers/manufacturers have introduced new cable designs with certain efficiencies or economical advantages. For example, sector-shaped cables are known to have larger equivalent cross sectional area of the conductor compared with classical pipe-type cables which can ultimately reduce the material cost. Other cable designs such as umbilical or mixed pipe-sector cables have also been introduced in practice. This calls for efficient modeling of cables with arbitrary cross-sections which is feasible via numerical techniques such as FEM or MoM. In this work we give an overview of using 2-D MoM as an efficient way for modeling power cable systems and summarize the progress made in this field. We also discuss existing challenges, limitations and future work.
