Abstract This paper focuses on the calculation of the ion flow field and total electric field of high voltage direct current(HVDC) transmission lines. Based on the method for calculating ion concentration in the coordinate system of the flux lines, differential equations and boundary conditions are obtained. A new method is presented, which transforms these differential equations to nonlinear algebraic equations by finite difference method. This method reduces the computational difficulty of differential equations and improves the calculation speed. In addition, it can be applied to solve both unipolar and bipolar ionic charge flow.

Key words： HVDC ion flow fields total electric fields finite difference method
