AI Technical Summary
Existing technologies struggle to accurately and promptly detect fault arcs in DC power supply systems, primarily due to low monitoring efficiency caused by missing characteristic quantities or data redundancy, inability of threshold judgment to adapt to complex operating conditions, and low monitoring accuracy.
By acquiring voltage and current data of the DC power supply system, linear fitting is performed using the least squares method to calculate stability, mean, deviation, and inflection point indices. Combined with multiple fluctuation state indices, it is determined whether an electric arc has occurred.
It enables accurate online monitoring of electric arcs in DC power supply systems, improving the intelligence and accuracy of monitoring and avoiding hazards caused by electric arcs.
