Multi-DGAS: A pattern based educational framework design for power transformers faults interpretation and comparative performance analysis
No full textTaking necessary measures in advance for early prediction of the transformer failures are very crucial. Dissolved gas in oil analysis (DGA) techniques that used in electrical power systems has become an internationally accepted standard in condition based maintenance (CBM) studies have high complexity and increasing demands of the quick-service-ready paradigm in power transformers. This standard includes the implementation steps of various complex DGA methods named basic gas, Rogers, Doernenburg, Duval triangle, and pentagon. Mentioned methods are quite complicated and their application steps are strict rules defined in detailed procedures. The adaptation of these methods to transformer maintenance procedures that prepared according to standards and tested for correctness creates a valuable tool. In this study, a pattern based educational framework has been designed to integrate state of arts DGA techniques help for trainers, graduate researchers working on DGA techniques, and also for maintenance teams while taking critical decisions on power transformers. Developed Multi-DGAS educational framework is designed for modular construction that can be integrated with online condition monitoring and diagnostic systems for electric power systems. Success of the proposed framework revealed with newly proposed pentagon method in regard with comparison of classical methods by using oil samples which have been taken under the energized condition of different 135 transformers within multi-phase which failure histories already known. Analysis of dissolved gases in transformer oil is performed according to ASTM-D 3612 procedure using 3800 GC Varian gas chromatograph apparatus.https://doi.org/10.1002/cae.2187
A map of the new television ad model landscape: Viewer and industry evaluations
No full textAs the digital TV revolution reaches Australian homes, it brings with it an evolving range of existing and potential advertising models. This study investigated the potential of 42 digital ad models made possible in the new television landscape. The models were tested and evaluated by 196 viewers from the general public and 239 industry professionals. Cluster analysis of the ratings found six ad model clusters: interactive models (26%), advertiser controlled (19%), program maximisers (14.3%), search (14.3%), objectionable (14.3%), and viewer controlled (12%). These clusters represent a picture of where television viewers and media buyers converged and diverged in their attitudes towards the new ad models
When beyond the comfort zone is the comfort zone
No full textThe advent of digital technologies is rapidly changing the ways in which people experience media characterised primarily by an increasing degree of control, choice and interaction. In this keynote presentation Professor Varan will explore how stepping out of our comfort zone as educators will often require that we enter into the comfort zone of our students, working to capitalise on new frontiers enabled through digital technologies. Professor Varan will share findings from a range of studies designed to better understand the psychology of the interactive viewer and explore their implications for new approaches to mediated education
Stability Analysis of Nonlinear Oscillations for AC-Fed Electric Arc Furnaces in Context of Bifurcation Dynamics
No full textBifurcation theory has been widely used to investigate dynamic behaviours of nonlinear components, and to make analytical answers on the formation of synchronous resonance, chaotic oscillations and ferroresonance oscillation phenomenon in electrical engineering. Bifurcation theory is also applied to perform stability analysis in nonlinear systems. This study aims to identify formations of nonlinear oscillations produced by AC-Fed Electric Arc Furnaces, in regard with bifurcation dynamics on the system. During the study, possible roles of small parameter changes of the sample arc furnace system around bifurcation points have been traced over time series analysis, phase plane analysis and bifurcation diagrams. A wide collection of useful dynamic analysis procedures for the exploration of studied arc furnace dynamics has been handled through the AUTO open-source algorithms
ELIMINATION OF HARMONIC INDUCED VIABLE BIFURCATIONS WITH TCSC FOR AC-FED ELECTRIC ARC FURNACES
No full textAC-fed electric arc furnaces (EAFs) are known with their unbalanced, excessively nonlinear and time varying load characteristics. The nonlinear oscillations produced by EAF operation cause several problems to interconnected feed system. Injection of harmonics/interharmonics and rising flicker effects on the feed system are two of major problems produced by EAF. These nonlinear effects result into quasistatic changes in the feed system parameters (L - R). In last decade many studies have been reported that such quasistatic changes in the feed system parameters result in viable bifurcation formations which strictly cause sudden and drastic changes on system behaviors. This paper presents an analytical control procedure to eliminate viable bifurcation points on L - I and R - I curves that cause sudden resonant peak arc currents. After control procedure, stability margins of EAF are extended into larger levels and viable bifurcation points on the feed system parameter have been eliminated. During study, possible roles of small parameter changes of uncontrolled EAF around bifurcation points and controlled EAF have been traced over time series analysis, phase plane analysis and bifurcation diagrams. A wide collection of useful dynamic analysis procedures for the exploration of studied arc furnace dynamics have been handled through the AUTO open-source algorithms
Chaotic ferroresonance and its control with sliding mode technique for voltage transformer circuits: a case study of manual single phase switching operation in three-phase transmission system
No full textChaotic ferroresonance is a nonlinear dynamic electrical phenomenon, which frequently occurs in a power system that comprises no-load saturable transformers, transmission lines (or cables) and single-phase switching with three-phase supply. This paper presents an extension of chaotic nonlinear bifurcation analysis on ferroresonance in a case study of manual single phase switching operation in three-phase transmission system. Analysis and classification methods are presented which provide chaotic analysis insights into the global behavior of ferroresonance. Analytical methods for nonlinear dynamic systems and MATCONT are used to exhibit characteristic curves such as a time-domain waveform, phase-plane, and bifurcation points
Synchronizations and secure communication applications of a third degree Malasoma system with chaotic flow
No full textChaos-based secure communication systems are alternative of standard spread-spectrum systems that enable spreading the spectrum of the information signals and encrypting information signals with simple and inexpensive chaotic circuitry. In secure communication area, like Lorenz, Chua, Rossler, Duffing etc., classical systems are widely used. Malasoma chaotic system is topologically simple but their dynamical behaviors are very rich and its synchronization and secure communication applications has not seen in literature. This paper aims for introducing a new chaotic system which is able to use as alternative to classical chaotic systems into secure communication fields. Mentioned novel model is also supported with electronic circuit model simulations that aim for being a synchronization circuit model using P-C method as chaotic masking communication circuit model. Modelling, synchronization and secure communication applications of Malasoma are realized respectively in MATLAB-Simulink environment. Retrieved results show that this novel chaotic system is able to use in secure communication fields. (C) 2016 Elsevier GmbH. All rights reserved
