A simple unsynchronized two‐end algorithm for faults location and identification in electrical distribution systems

Abstract

Purpose

The purpose of this paper is to identify a new and simple two‐end algorithm for fault location identification and characterization, in electrical distribution systems.

Design/methodology/approach

The developed diagnostic algorithm is based on a simple model of the network using a lumped parameters representation.

Findings

Test results have proved the approach to be efficient, allowing a precise fault identification and location while not requiring synchronized measures from the two ends.

Research limitations/implications

There is a need for measurement systems at all MV/LV substations.

Practical implications

Applicability with limited investments is not possible where metering systems are not so diffused, although smart grids and DG units require such infrastructures. Moreover, utilities are quite interested in such issues, since the new required quality standards put severe constraints on faults management and clearance.

Originality/value

The paper presents a new and easier diagnostic algorithm for faults diagnosis in distribution systems.
