Popis: Ultra high voltage direct current (UHVDC) transmission has took a significant part in power grid. However, the increase of transmission efficiency hindered by electromagnetic environment problems caused by its corona discharge. Therefore, the corona discharge of UHVDC transmission line has been spotlighted. Considering the complex reaction of microscopic particles in the air during the discharge process, this paper integrates each split conductor as a discharge source located on the split centerline, and simplifies the discharge of the transmission line into a one-dimensional model of a coaxial cable. The study can help us to explore the physical process and microscopic particle motion characteristics of corona discharge deeply. Besides, it is an important guideline for studying and preventing electromagnetic environment problems from the root cause.
