A dynamic wavelet network based adaptive load frequency control in power systems

Köklükaya, Etem (ELSEVIER SCI LTD, 2005)

This paper proposes a new adaptive load frequency controller based on a 'dynamic wavelet network (DWN)' that has lag dynamics, nonorthogonal mother wavelets as activation function and interconnection weights. A DWN is ...
A new 3D chaotic system with golden proportion equilibria: Analysis and electronic circuit realization

Pehlivan, İhsan; Uyaroğlu, Yılmaz (PERGAMON-ELSEVIER SCIENCE LTD, 2012)

This article introduces a new three-dimensional quadratic continuous autonomous chaotic system with golden proportion equilibria, which can generate single folded attractor. Some basic dynamical behaviors and the dynamical ...
A new approach for measuring RMS value and phase angle of fundamental harmonic based on Wavelet Packet Transform

Vatansever, Fahri; Özdemir, Ayhan (ELSEVIER SCIENCE SA, 2008)
A New Approach For Treatment of Chronic Obstructive Pulmonary Disease

Sedat Orenc; Uçar, Muhammed Kürşad; Bozkurt, Mehmet Recep; Bilgin, Cahit (IEEE, 2017)

Chronic Obstructive Pulmonary Disease (COPD) is a persistent respiratory disease usually caused by toxic gases. The diagnosis is made by a specialist doctor on a report taken by a specialist technician using a spirometer. ...
A new chaotic attractor from general Lorenz system family and its electronic experimental implementation

Pehlivan, İhsan; Uyaroğlu, Yılmaz (TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2010)

This article introduces a novel three-dimensional continuous autonomous chaotic system with six terms and two quadratic nonlinearities. The new system contains two variational parameters and exhibits Lorenz-like attractors ...
A new digital relay for generator protection against asymmetrical faults

Bayrak, Mehmet (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2002)

Under unbalanced conditions the three phase instantaneous power oscillates at twice the power system frequency. The magnitude of these oscillations can be used as a measure of the system unbalance. This paper has introduced ...
A New Sequential AC-DC Power Flow Algorithm for Multi-Terminal HVDC Systems

Yalçın, Faruk; Arifoğlu, Uğur (WILEY, 2017)

This paper presents a new algorithm based on the sequential method for power flow calculation in integrated multi-terminal, high-voltage, direct current (HVDC) systems. Unlike similar studies in the literature, a real ...
A new sequential power flow algorithm for AC/DC systems including independent multiterminal DC subsystems

Yalçın, Faruk; Arifoğlu, Uğur (TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2017)

This paper presents a new algorithm based on the sequential method for power flow calculation in multiterminal AC/DC systems. The proposed approach differs from other similar studies in the literature by handling two main ...
A NOVEL SLITTED TOOTH CORE DESIGN to DECREASE LEAKAGE FLUX in INDUCTION MOTOR

Turan, Mustafa (GAZI UNIV, FAC ENGINEERING ARCHITECTURE, 2012)

Induction motors, due to the extensive use in industrial applications, are dominant factor in terms of energy consumption in many countries. Especially in recent years, many studies have been realized to achieve higher ...
A POWER BASED ALGORITHM DESIGN FOR DETECTION OF BROKEN ROTOR BARS FAULTS IN THREE PHASE INDUCTION MOTORS

Bayrak, Mehmet; Küçüker, Ahmet (GAZI UNIV, FAC ENGINEERING ARCHITECTURE, 2016)

Many sinusoidal components different from power system frequency in instantaneous power occur in three phase induction motors during faults and unbalanced conditions. The amplitude and frequency of these components give ...
A reactive power control relay design with a new approach

Özdemir, Ayhan (SPRINGER, 2006)

In this study.. the design and implementation of a mixed-signal microcontroller based reactive power control relay that is superior to existing reactive power control relays is presented. This device measures the fundamental ...
A Weak Signal Detection Application Based on Hyperchaotic Lorenz System

Abdullah Gokyildirim; Uyaroğlu, Yılmaz; Pehlivan, İhsan (UNIV OSIJEK, TECH FAC, 2018)

Due to accurate capability to detect weak signal, chaotic oscillators have become an interesting topic for many scientific researches. In this paper, two hyperchaotic Lorenz systems are presented to detect weak signal. ...
