Research on Single-Phase Ground Fault Line Selection and Positioning System of Low-Current Grounding System

The role of fault location in single-phase grounding systems is very important, but there is a problem of poor accuracy. The original positioning method solves the fault location problem in single-phase grounding system, and the diagnostic ability is low. Therefore, this paper proposes a low-current grounding diagnosis method to analyze the talents of single-phase grounding system. Firstly, the big data theory is used to evaluate the talents, and the fault location requirements are divided to reduce the interference factors in the fault location. Then, the big data theory requires the single-phase grounding system to form a fault location scheme, and conducts comprehensive fault diagnosis on the fault location requirements 。 MATLAB simulation shows that under the condition of stable power flow of the power grid, low-current grounding diagnosis method are better than those of PLD teaching mode. Determine the location of the failure.
