Previous Issues

Electrical and Electronics Engineering is a dynamic field which involves development and application of modern technology such as analogue and digital circuitry, microelectronics, microprocessors and memory devices, signal processing and data communications, control and expert systems,electromagnetism and telecommunication, electric machines, power systems and electricity distribution systems. The rapid development and innovation in these areas in the last two decades have undoubtedly improved our life a great deal in various aspects and the trend is expected to continue in the future. Realizing the growing importance of this field, IUP has come up with a quarterly journal, The IUP Journal of Electrical and Electronics Engineering.

Detection and Error Analysis of High Impedance Fault Using Wavelet Transform, Traveling Wave and Support Vector Machine

--Supriya Golhani and Sandeep Bhongade

Physical connection between phase conductors with surface below the lines, trees and walls of building leads to High Impedance Fault (HIF). This will cause ignition via arc or heat of substances. Detection of HIF is difficult because occurrence of them leads to a slight increase in load current, and it can be considered as a usual increase in the value of load current incorrectly. Due to HIF, the whole energy produced by a power company is not achieved by the loads. For detecting fault accurately and quickly, a method based on Wavelet Transform (WT) and Support Vector Machine (SVM) has been proposed. WT is used as feature extraction and decomposes current or voltage waveform. Initially, current or voltage waveform is decomposed in the first level and these features are again decomposed in the subsequent level. Sampled data collected by DWT is used as input to SVM. SVM is used as classifier.

Fuzzy Logic Controller-Based SSR Mitigation in Turbine-Generator shaft Using SVC

--A Kathiravan and Alamelu Nachiappan

Subsynchronous Resonance (SSR) oscillations in a power system are most unwanted phenomenon. The interaction between torsional system and electrical system exhibits a situation of SSR oscillations. These oscillations, if not sufficiently damped, grow tremendously, leading to stability problem. Though Power System Stabilizer (PSS) damps subsynchronous oscillations effectively over the period of time, still oscillations due to SSR remain a challenge to it. Flexible AC Transmission System (FACTS)-based compensators play an important role in mitigating SSR oscillations most comprehensively. The paper proposes a fuzzy tuned Static VAR Compensator (SVC) for analyzing the SSR phenomenon in an IEEE Second Benchmark Multimass (ISBM) system. An ISBM model with SVC is carefully designed using Fuzzy Logic Damping Controller (FLDC) for SSR analysis using MATLAB/Simulink. The simulated results showed higher convergence rate and better SSR damping capability.

Simulation of Surface Sensing Behavior of Pt Doped SnO2 (110) with CO

--Manju Ahuja, B Prasad and Rajneesh Talwar

To study the sensing mechanism at atomic, geometrical and electronic structural levels, density functional theory (DFT) technique is useful. Based on ab initio, DFT calculations for CO gas sensing behavior on undoped and Pt doped SnO2 are done. After surface relaxation, optimum adsorption site is selected based on adsorption energy calculated for four different sites, O2C (bridging oxygen), Sn6c (6 fold Sn), Sn5c (5 fold Sn) and O3c (plane oxygen), and CO sensing behavior is observed on favorable site. For estimation of conductance, which is a measure of sensitivity of gas sensing system, analysis of related physical parameters like surface density of states (DOS) and Mulliken population analysis are done. Enhanced sensitivity is observed for Pt doped surface as compared to undoped ones, which is in agreement with the experimental results. Modeling and simulations help to optimize the sensor for any specific application, prior to fabrication. Conclusions help in designing the framework of SnO2-based CO gas sensor.

A Look Ahead Load Shed Strategy for Line Overload Alleviation Based on the Sensitivity of a Severity Index Incorporating Distributed Generations

--Pradeep Purey

The paper describes a new methodology for load shed at buses incorporating the effect of Distributed Generation (DG) at selected buses. The strategy gives load shed amount at selected buses in anticipation of the predicted load in the next interval. The method first exploits the capability of DG present at various buses for achieving line overload alleviation and then, if necessary, load shed is executed at load buses. It is a monovariable method, where load shed is executed at buses having the highest sensitivity of Severity Index (SI), and then another bus is selected in the next iteration based on the magnitude of sensitivities. The algorithm has been implemented on a 30-bus test system.

Automated Teller Machines (ATMs): The Changing Face of Banking in India

Bank Management
Information and communication technology has changed the way in which banks provide services to its customers. These days the customers are able to perform their routine banking transactions without even entering the bank premises. ATM is one such development in recent years, which provides remote banking services all over the world, including India. This paper analyzes the development of this self-service banking in India based on the secondary data.

The Information and Communication Technology (ICT) is playing a very important role in the progress and advancement in almost all walks of life. The deregulated environment has provided an opportunity to restructure the means and methods of delivery of services in many areas, including the banking sector. The ICT has been a focused issue in the past two decades in Indian banking. In fact, ICTs are enabling the banks to change the way in which they are functioning. Improved customer service has become very important for the very survival and growth of banking sector in the reforms era. The technological advancements, deregulations, and intense competition due to the entry of private sector and foreign banks have altered the face of banking from one of mere intermediation to one of provider of quick, efficient and customer-friendly services. With the introduction and adoption of ICT in the banking sector, the customers are fast moving away from the traditional branch banking system to the convenient and comfort of virtual banking. The most important virtual banking services are phone banking, mobile banking, Internet banking and ATM banking. These electronic channels have enhanced the delivery of banking services accurately and efficiently to the customers. The ATMs are an important part of a bank’s alternative channel to reach the customers, to showcase products and services and to create brand awareness. This is reflected in the increase in the number of ATMs all over the world. ATM is one of the most widely used remote banking services all over the world, including India. This paper analyzes the growth of ATMs of different bank groups in India.
International Scenario

If ATMs are largely available over geographically dispersed areas, the benefit from using an ATM will increase as customers will be able to access their bank accounts from any geographic location. This would imply that the value of an ATM network increases with the number of available ATM locations, and the value of a bank network to a customer will be determined in part by the final network size of the banking system. The statistical information on the growth of branches and ATM network in select countries.

Indian Scenario

The financial services industry in India has witnessed a phenomenal growth, diversification and specialization since the initiation of financial sector reforms in 1991. Greater customer orientation is the only way to retain customer loyalty and withstand competition in the liberalized world. In a market-driven strategy of development, customer preference is of paramount importance in any economy. Gone are the days when customers used to come to the doorsteps of banks. Now the banks are required to chase the customers; only those banks which are customercentric and extremely focused on the needs of their clients can succeed in their business today.
