A power quality analysis scheme using adaptive subband decomposition

Abstract

In this work, a new event detection method for power quality analysis based on the statistical analysis of adaptive decomposition signals is presented. The combination of an adaptive prediction filter-based subband decomposition structure with a rule-based histogram analysis block produced successful detection and classification parameters on Our real life power system transient data. Proposed scheme is implemented using MATLAB (TM) Simulink DSP Blockset. Copyright (C) 2008 John Wiley & Sons, Ltd.
