The frequency characteristic simulation transmission line, multi-impedance tower model and air gap breakdown model were established by ATP-EMTP, the influence of electrode line on back flashover level for HVDC line was studied, and the arcing horn discharge characteristics was researched. The results showed that, back flashover performance of HVDC line could obviously be improved by earth electrode line, and lasting arc could be established by DC current in the single pole operation mode.
