Abstract

It was reported that airborne suspended particles charged in ion flow generated by corona discharge in the vicinity of HVDC lines can be harmful to electromagnetic environment. The frequent occurrence of sandstorm and haze and quite a number of UHVDC transmission lines being going through planning, constructing and operating, make it imperative to understand the effects of particles on electromagnetic environment of HVDC lines. Space charge effect of particles is one of those effects. To explore this one, it is of need to clarify the charging mechanisms of particles surrounding HVDC lines. This paper is devoted to dig into this topic. In addition to that, the importance of these mechanisms to the electromagnetic environment of HVDC lines are evaluated. The results show that charging by artificial electric field ionization is major and the crust radiation ionization and particle collision have to be considered in some special cases and other charging mechanisms such as particle electric field emission are not needed to be counted. This paper avails understanding the particle charging around HVDC lines, setting paves to constructing a reasonable mathematical model describing the interplay between particles and ion flow fields.
