Abstract
This paper discusses the effect according to the change of grounding system modeling in substation. Substation grounding system is modelled by CDEGS and EMTP. Node voltages of grounding system is variously analysed by 3 grounding cases and 4 kinds of transient frequency ranges. The results of this paper will contribute to advance the grounding system modeling of substation in the range of high frequency transient such as lightning surge.
