Abstract

The grounding system of the ultra-high voltage substation is of great significance in safe operation of the substation. The grounding resistance value of the grounding system of the ultra-high voltage substation in the basic plan is far more than the allowable value. The paper analyzes the common resistance reduction measures, considers the safety and the practicability according to the actual situations of the substation and puts forwards the following several possible resistance reduction measures of exterior-leading grounding, oblique grounding and vertical grounding, deep well grounding, blasting grounding and so on. The analysis result shows that the grounding resistance value can be reduced to the allowable range.
