Abstract Since the combustion of secondary arcs in UHV transmission lines is long. If these arcs can’t be extinguished in time, the single-phase automatic reclosure would be failed, thus having bad effect on supply security and system stability. As a result, it is necessary to study secondary arc currents of UHV transmission lines. In this paper, various secondary arc current’s calculation methods and their advantages and disadvantages are firstly summarized. Meanwhile, the shortages of researches at present on secondary arc current in UHV transmission lines are pointed out, of which one is lacking in simulation and experimental data, the other is without consideration of the arc model. Next, according to the Huainan-Shanghai 1000kV UHVAC double-circuit transmission project which is under construction in China, its simulation model, including models of system, line and arc, is built in details with PSCAD/EMTDC software. Finally, on the base of the built model, simulation research on secondary arc current is presented in the paper. The secondary arc current and its time duration are calculated respectively in the cases of single-point fault, two-point fault as well as under the circumstance when line load ratios are different. The results show that secondary arc current of the project wouldn’t have influence on accomplish of the single-phase automatic reclosure.

Key words： UHV secondary arc current arc model simulation analysis single-phase automatic reclosure lumped parameter distributed parameter twice modal transformation
