Detection of Mechanical Faults in Induction Motors Supplied with Adjustable Speed Drives
Başaran, Murat; Ece, Doğan Gökhan (IEEE, 2009)In this work, the mechanical faults that occur in induction motors, which are widely used in industry due to their simple and rugged construction and cost effective pricing, are analyzed. The certain fault modes are generated ... -
Detection of Voltage Flicker and Voltage Harmonic Using Hilbert Huang Transform
Önal, Yasemin; Gerek, Ömer Nezih; Ece, Doğan Gökhan (IEEE, 2014)Hilbert Huang Transform, which was suggested by Huang and improved by Flandrin and his group, is a new signal processing method. The analysis of nonlinear and non stationary signals can use HHT. This paper deals with the ... -
KISA DÖNEM KIRPIŞMA ŞİDDETİNİN HILBERT-HUANG DÖNÜŞÜMÜ İLE HESAPLANMASI
Bu makalede güç sistemlerinde kısa dönem kırpışma(flicker) şiddeti Pst’yi hesaplamak için Hilbert Huang dönüşümünün (HHT) kullanımına dayalı bir yaklaşım önerilmektedir. HHT lineer ve durağan olmayan sinyallerin analizinde ... -
A novel feature vector consisting of Ar-Ma model parameters for motor fault classification
Ece, Doğan Gökhan; Gerek, Ömer Nezih (IEEE, 2006)In this work, AR-MA parameters corresponding to zeros and poles of the z-plane model are extracted from the sampled current waveform spectra, and considered as elements of a feature vector to classify faulty motors. The ... -
Power quality event detection using joint 2-D-wavelet subspaces
Ece, Doğan Gökhan; Gerek, Ömer Nezih (IEEE-Inst Electrical Electronics Engineers Inc, 2004)In this work, we present a novel two-dimensional (2-D) representation of power system waveforms for the automatic analysis and detection of transient events. The representation is composed of a matrix whose rows are formed ...
