Abstract

With the development of HVDC, transmission capacity and transmission voltage level are both increasing. Under this situation, designing reliable grounding grid is more demanding. For areas with high soil resistivity, the grounding parameters can hardly meet relevant requirements. To solve this problem, this paper takes Luxi convertor station as an example to illustrate the designing process, and analyzes different design schemes. The results show that for areas with high deep soil resistivity the effect of using vertical grounding rods is slight, while the one of lengthening horizontal grounding objects is evident.
