Research on Traveling Wave Fault Location in Medium Voltage Distribution Network Based on Local Feeder Automation
Based on the principle of traveling wave fault location,a scheme is proposed to achieve fault distance measurement in addition to the fault location function of voltage-time feeder automation(FA).The distribution automation master station,leveraging the positioning results from the voltage-time FA system,further retrieves and analyzes the traveling wave recording files from the boundary switches within the fault interval,thereby realizing fault distance measurement.This approach extends the conventional functionality of feeder automation terminals,enabling precise fault point location with practical application value.
