A new methodology for distribution systems faults identification, location and characterization

Abstract

Purpose

Identify a new methodology for fault characterization, identification and location in electrical distribution systems, based on the use of matrix algebra.

Design/methodology/approach

The developed diagnostic methodology is based on a high precision analytical model of the network using a distributed parameters representation.

Findings

Test results have proved the approach to be efficient and precise, while providing a generalized quadripolar model of a line affected by the most common kinds of fault.

Research limitations/implications

Generalization to a greater number of fault cases, experimental tests.

Practical implications

Utilities are quite interested in such items, since the new required quality standards put severe constraints on faults management and clearance. On the other hand, the system requires a rather complete measurement equipment of secondary substations.

Originality/value

The paper presents a new diagnostic technique for faults identification, location and characterization in distribution systems.
