AI Technical Summary
In distribution networks, due to the numerous branch lines and the non-unique distances to faults, existing technologies struggle to quickly and accurately locate fault points and control switch tripping, resulting in a lack of effective means for the rapid isolation and handling of faulty lines.
By injecting a modulated traveling wave signal containing switch position or fault distance codes into the line, and using a traveling wave identification device to analyze the current traveling wave waveform, the switch where the fault point is located can be determined and its tripping can be controlled, thereby achieving rapid isolation of the fault point.
It enables rapid isolation of faulty lines, improves the safety of maintenance personnel and equipment, reduces power outage time for non-faulty lines, and improves power restoration efficiency.
