Abstract
The provided are a line fault detection method, system, equipment, and a computer-readable storage medium. The line fault detection method comprises the following steps: Inject a pulse signal into the grounding electrode line and acquire fault voltage traveling wave data responding to the fault point in the grounding electrode line based on the measuring spot; Based on the fault voltage traveling wave data and a preset step size, determine the voltage forward traveling wave sequence and voltage reverse traveling wave sequence for the entire grounding electrode line; Based on the corresponding energy superposition expressions of the voltage forward traveling wave sequence and the voltage reverse traveling wave sequence, determine the integral value sequence of the traveling wave product within a preset time period; Based on the maximum mutation point in the integral value sequence, determine the fault distance.
