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 ... -
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 ... -
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 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 ...
