Abstract The flux tracing method is frequently applied for predicting the ion flow field of HVDC transmission lines, the error of which is mainly caused by Deutsch assumption. In this paper, a new iterative method of characteristics is proposed based on the methodology of flux lines (or characteristic lines). The directions of the characteristic lines are modified in the iterations using the updated electric field. Thus Deutsch assumption is not made for the proposed method. Results show that the present method has a better performance on the ground-level electric field and ion density, space charge distribution, flux conservation law and power losses. In addition, errors using two types of boundary conditions are compared and analyzed.

Key words： Ion-flow field total electric field HVDC transmission lines Deutsch assumption iterative method of characteristics
