2-D analysis and compression of power-quality event data
Gerek, Ömer Nezih; Ece, Dugan Gökhan (IEEE-Inst Electrical Electronics Engineers Inc, 2004)This paper introduces a novel two-dimensional (2-D) representation of the power quality event data. 2-D discrete-time wavelet transform is applied to the 2-D representation of real-life event data. The proposed representation ... -
A 2D representation for analysis and coding of power quality events
Gerek, Ömer Nezih; Ece, Dugan Gökhan (IEEE, 2003)In this work, we demonstrate examples about uses of practical image processing techniques over a new interpretation of power quality event data. Power quality event data are 1D data obtained from a real life system with ... -
An adaptive statistical method for power quality analysis
Gerek, Ömer Nezih; Ece, Dugan Gökhan (IEEE-Inst Electrical Electronics Engineers Inc, 2005)Digital fault recorders installed for monitoring current and/or voltage waveforms acquire and store vast amount of waveform data for post processing. Because of this, effective offline automated event detection from acquired ... -
Detection of disturbances in energy system signals using Gaussian distribution fitness test
Gerek, Ömer Nezih; Ece, Dugan Gökhan (IEEE, 2004)In this work., a method based on higher order statistics (HOS) is proposed to detect disturbances in energy system voltage and current waveforms due to faults and various system events. During the normal operation of the ... -
Modeling of hysteresis and power losses in transformer laminations
Akçay, Hüseyin; Ece, Dugan Gökhan (IEEE-Inst Electrical Electronics Engineers Inc, 2003)In this paper, a method for the representation of hysteresis and power losses in the laminations of power transformers is proposed. The developed model is based on data supplied from steel manufacturer and able to predict ... -
Power quality event detection using joint 2D-wavelet subspaces
Gerek, Ömer Nezih; Ece, Dugan Gökhan (IEEE, 2003)In this work, we present a novel 2D representation of power system waveforms for the automatic analysis of transients. The representation is composed of a matrix whose rows are formed by time segments of digital waveforms. ... -
Power-quality event analysis using higher order cumulants and quadratic classifiers
Gerek, Ömer Nezih; Ece, Dugan Gökhan (IEEE-Inst Electrical Electronics Engineers Inc, 2006)In this paper, we present a novel power-quality (PQ) event detection and classification method using higher order cumulants as the feature parameter, and quadratic classifiers as the classification method. We have observed ...
