Design and Implementation of Real-time Fault Location Experimental System for Teaching and Training University Students

Abstract

The fault location problem is one of the most important issues in power system operation and control. To obtain an experimental system for teaching and training electrical engineering students, this paper performed a study to design and implement a real-time fault location laboratory-scale model from practical hardware components. The impedance-based fault location method is embedded in the system to determine the distance to fault in the transmission line. Furthermore, the monitoring and controlling program is designed by the Matlab App Designer – A new professional app to create the graphical user interface and use the integrated editor quickly. Several fault types including three-phase fault, phase-to-phase fault, phase-to-ground fault are created to evaluate the performance of the fault location experimental system. The real-time measurement results which are acquired and observed on the user guide interface of the program confirm the effectiveness of the experimental system; therefore, the system can be considered a powerful tool for electrical engineering students.

A new method for estimating fault location in radial medium voltage distribution network only using measurements at feeder beginning

“…In addition, the new methods based on the zero-sequence component characteristic [29] and based on the modal analysis [30] were proposed for fault location in distribution networks. The authors in [31] applied an impedancebased method to design and implement a real-time fault location experimental system for teaching and training universities in which voltage and current measurements at the monitoring point are recorded to determine the distance to the fault. The approach based on the phasor measurement of a real digital fault recorder was proposed in [32].…”
