Abstract The space charges generated from the conductors of HVDC transmission lines due to the corona will form the ion-flow flied and enhance the electric field on the ground level. In this paper, a new hybrid method is proposed. The flux tracing method is used in ambient space of conductors while the upstream finite element method is applied in the space far away from the conductors. D-N algorithm is used to compute the coupling in each domain. On one hand, the error due to Deutsch assumption in flux tracing method is avoided. The influence of the wind can be included. On the other hand, the element number of the finite element is significantly reduced and the computational efficiency is improved. Moreover, the initial values on the interface can be provided by the flux tracing method. The iteration can be finished within a few steps. The calculations agree well with the experiment data and the efficiency is improved. Finally, the ground-level electric field and ion current density of ±800 kV and ±500 kV double-circuit lines are analyzed.

Key words： Ion-flow field HVDC transmission lines flux tracing method upstream finite element method domain decomposition method
