Název v původním jazyce

Higher-Order FDTD, FE and Meshless Methods for Studying Lightning-Excited Multiconductor Distribution Lines

Popis výsledku v původním jazyce

Formulae of centered-difference approximations of first- and second-order partial derivatives of the function u(x,t) in spatial domain based on Taylor series expansions are presented in many literatures of Finite Difference Method (FDM). This approach isalso understood as a very basic algorithm. In this paper, we investigate the other approach which is to use higher-order Finite Element (HO-FE) analysis. The obtained results have been seen that formulae of higher-order central FE and FD approximationsare similar and the proposed approach is simpler than the one of Taylor series expansions. In addition, an introduction to a kind of Meshless Methods, Smooth Particle Hydrodynamics (SPH) method, is also presented. Finally, three numerical methods are applied to calculate lightning-induced voltages on multiconductor distribution lines. The solutions of various numerical methods are illustrated and compared by means of graphs.
