Gas Insulated Substation Grounding System Design Using the Electromagnetic Field Method
This paper presents an accurate electromagnetic field theory method to model and analyze a realistic grounding system involving gasinsulated substation (GIS).The GIS structure,ground conductors,massive reinforced steel rebar,and aboveground bus bars were modeled accurately in detail to evaluate GIS safety.The study takes the effects of the inductive coupling between GIS inner high-voltage buses and outer enclosures into account.Soil resistivity test data interpretation and fault current distribution analysis were carried out as well.The study demonstrates how advanced simulation approaches can be used to analyze complex grounding issues for a GIS substation and produce accurate results.
