| Abstract:The grounding network subsystem， which acts as a key link in the power system， plays an important role in ensuring the safe operation of the power system and its equipment， and various grounding techniques for the system have received wide attention. The deep-ground-well method based on pressure grouting has been widely used due to its advantages in decreasing grounding resistance and economical benifits. In this paper， the reduction mechanism and grouting process of the deep-ground-well method based on pressure grouting are studied. Combined with the reduction of the actual substation， the variation law and stability of the grounding resistance and the derating resistance coefficient with apparent soil resistivity are analyzed in detail through the test and data analysis. |
