| Abstract:With the grid connection of a large number of new energy generation methods and the popularity of ultra-high voltage transmission, the grounding network of the old substation finds it difficult to meet modern safety requirements. Thus the transformation of the grounding network has gradually been put on the agenda. To explore a more reasonable way of grounding network reconstruction, based on the IEEE std80-2000 to establish the relevant mathematical model, the influence of grounding network footprint, grounding conductor length and coupling on the basic performance parameters of the grounding network is studied. From actual engineering data, this paper uses CDEGS software to establish the relevant substation grounding network model, and puts forward six optimization modifications for simulation research. Finally, the simulation results under different schemes are integrated to cope with various engineering situations, and an optimization scheme with better overall performance is obtained. |
