Fault Location Based on Synchronized Measurements: A Comprehensive Survey

Abstract EN

This paper presents a comprehensive survey on transmission and distribution fault location algorithms that utilize synchronized measurements.

Algorithms based on two-end synchronized measurements and fault location algorithms on three-terminal and multiterminal lines are reviewed.

Series capacitors equipped with metal oxide varistors (MOVs), when set on a transmission line, create certain problems for line fault locators and, therefore, fault location on series-compensated lines is discussed.

The paper reports the work carried out on adaptive fault location algorithms aiming at achieving better fault location accuracy.

Work associated with fault location on power system networks, although limited, is also summarized.

Additionally, the nonstandard high-frequency-related fault location techniques based on wavelet transform are discussed.

Finally, the paper highlights the area for future research.
