Single-Phase Ground Fault Diagnosis Method of 10 kV Distribution Line Based on Traveling Wave Signal
To solve the problem of low accuracy in diagnosing single-phase grounding faults in distribution lines,a research on a 10 kV distribution line single-phase grounding fault diagnosis method based on traveling wave signals was carried out by introducing traveling wave signals.Firstly,the fault characteristics of the distribution line are extracted using traveling wave signals.Then,the traveling wave recording points at both ends of the distribution line are set,and the fault location is determined through distance measurement to achieve single-phase grounding fault diagnosis of the distribution line.The results show that after applying this method,the accuracy of diagnosing and identifying single-phase grounding faults in distribution lines reaches over 98.5％,indicating high feasibility.
