To develop a new numerical algorithm in Matlab that can determine the distance to the fault on a transmission line, the unknown fault location will be determined from voltage and current phasor, synchronously measured at both line terminals.

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.
