AbstractThe grounding grid is the basis for maintaining the safe operation of the power system. Proving the health status of the grounding grid under the soil is the top priority of the maintenance of the power system. When the grounding grid is corroded and fractured, its topology will also change accordingly. In this paper, CDEGS is used for modeling, and the spectral impedance data of grounding grids under different topological structures are obtained by spectrum method, the spectral impedance characteristics of various topological structures are analyzed, and the changes of spectral impedance characteristics under different geological conditions are studied by changing soil resistivity. The ground grid model was established on the spot to collect on-site test data, and the simulation results were compared. This research can further reduce the cost of grounding grid status detection and promote social development.
