An Analysis of Fault Location Algorithm for Transmission Lines Using Synchronized Measurements
• To retrieves all triggered event reports from relays and digital fault recorders (DFRs) automatically. With these reports, the system identifies the faulted transmission line(s) within the transmission network.
• To determine the fault type and calculates the fault location and fault resistance using multi-terminal fault location methods for different types of power lines, including overhead lines, underground cables, and composite lines that include both overhead line and underground cable sections.
• To uses fault location methods that are accurate under fault resistance, parallel-line mutual coupling, system non-homogeneity, and load.
• To introduce a real-time fault location system that uses line protection relays and displays fault location information at the control center within less time after the fault occurrence when using Ethernet-based communication.
