| Abstract: | The fault location algorithm based on a differential equation-based approach for a transmission line
employing a unified power flow controller (UPFC) using synchronised phasor measurements is presented.
First, a detailed model of the UPFC and its control is proposed and then, it is integrated into the transmission
system for accurately simulating fault transients. The method includes the identification of fault section for a
transmission line with a UPFC using a wavelet-fuzzy discriminator. Features are extracted using a wavelet
transform and the normalised features are fed to the fuzzy logic systems for the identification of fault section.
After the identification of the fault section, the control shifts to the differential equation-based fault locator
that estimates the fault location in terms of the line inductance up to the fault point from the relaying end.
Shunt faults are simulated with wide variations in operating conditions and a pre-fault parameter setting. The
