Real-time detection of transient disturbances in electric power network

Krzysztof Duda, Andrzej Bień

Abstract

In this paper we present real-time application for detecting, extracting and automatic classification of transient disturbances in electric power network. Proposed method was implemented on Texas Instruments C6713 DSK toolkit and tested with both laboratory-generated and real-world power network signals with good results. For each detected transient a set of parameters is evaluated including the time of occurrence, duration time, energy and frequency spectrum. Classification of disturbance can relay on arbitrary combination of those parameters (e.g. one can be interested in finding disturbances with sufficiently high energy and specified duration time). The presented implementation was design to be a part of complex system for Power Quality (PQ) monitoring.
