Study of methods for fault location in underground electrical distribution systems

Abstract

Faults on transmission and distribution systems are the most common drawbacks that affect underground distribution systems. To mitigate the problems caused by shortages, studies are conducted to develop methods of fault location continually faster and more accurately. The purpose of this project is to gain knowledge about the various methods of fault locating and developing simulations based on models of electric power transmission lines. The objective of this project is to pinpoint the advantages and disadvantages of using different methods of locating faults in underground distribution systems, by simulating electromagnetic transients in single-phase systems containing linear lumped and distributed parameters. To accomplish these aims, electromagnetic transient simulations will be implemented by using software like PSCAD and MATLAB. Modeling features available in PSCAD allow modeling of electrical systems and has been widely applied by researchers all over the world. (AU)
