Identification of fault location in a Multi-Terminals Network using Morphological Gradient Technique

Abstract

This paper presents a simple, effective and fast technique based on morphological gradient to identify fault location in a multi-terminals network. Mathematical Morphology Gradient (MMG) relaying algorithm and other related algorithms such as tripping and fault location schemes are also presented in this paper. The proposed technique relies on measuring the minimum stamping time between relay indices to identify the faulty zone. The technique is evaluated through extensive simulation study using alternative transient program (ATP). Simulation results show that, the proposed technique has the capability of monitoring complex power systems and effectively identifying fault location in real time.
