摘要：

As ultra-high-voltage direct current (UHVDC) projects are constructed in China, the electromagnetic environment problem is widely concerned. One of the most important problems is the ion-flow field including the human body under the UHVDC lines. But it has not been analyzed sufficiently. In this paper, the 3-D upstream finite-element method, a new method to analyze the 3-D ion-flow field under HVDC lines is proposed and verified by experiments. Then, the method is used to calculate the ionized electric field and the ion current of the human body model under the UHVDC lines. The ionized electric field is significantly distorted by the human body. According to the results, the ionized electric field and the ion current of the human body remarkably increase with the height of the human body model. The results could provide a reference for evaluating the electromagnetic environment and the personal feeling test under the UHVDC lines.
