摘要

This paper uses EMTP (Electro-Magnetic Transient Program) software to establish the secondary arc current calculation model of a 500kV Power Station's transmission line, and through theoretical derivation combined with simulation calculation to study the influence of transmission line's length on the magnitude of secondary arc current, and draw the following conclusions: The capacitance component produced by the interphase capacitance mixing of the non-faulty phase accounts for the main part, which is basically linear with the line length. Line length has obviously effect on the secondary arc current. As the line length increases, the peak value of the secondary arc current also increasing and decays slower, meanwhile, the stable secondary arc current is greater.
