Abstract This paper introduces the design scheme of grounding system of Yunxiao back-to-back converter station. Based on the test data of soil resistivity, this paper analyzes the soil structure by modeling. According to the soil structure model and the site leveling design scheme of the station, the grounding grid design scheme combining the deep well grounding electrode and the external grounding network of the slope is targeted. Through simulation analysis, the influence of the deep well grounding electrode and the external grounding network on the grounding design of the converter station is compared. Finally, the accuracy of the simulation analysis data is verified through on-site measurement data, ensuring the safety and reliability of the grounding scheme for this station.
