Comparison of two Different Approaches for Harmonic Analysis of Single Phase Inverter
Sathisha K, Dr. Pinto Pius A.J.
Abstract:
In this paper we present, harmonic analysis of single phase inverter based on unipolar pwm and bipolar pwm techniques. Simulation results of both the methods are also highlighted. In order to find the Total Harmonic Distortion (THD), FFT is used using mat lab/simulation software. It is found that performance of unipolar switching technique is better than bipolar switching technique in comparison of THD. It is observed that minimum value of THD of unipolar switching technique is 5.28 % and Bipolar switching technique is 11.03 % in case of amplitude modulation. Also in the case of frequency modulation we get 5.52% and 7.72% respectively.

Smart Energy Meter Management using GSM
Mallikarjun Bhagawati, Vinod Hiremani, Suresh M
Abstract:
The present electricity billing system in India is inaccuracy flat and time consuming. Errors get introduced at every stage of energy billing like errors with electro-mechanical meters, human errors while noting down the meter readings and errors while processing the paid bills and the due bills. There is no proper way to know the power usage details, load shedding schedules and power robbery. One of the remedies for these drawbacks is implementation of a Smart energy meter. This paper is on the development of a smart energy meter which is having capabilities like remote monitoring and controlling of energy meter. Here the consumer pays the electricity bill well in advance before the energy consumption which would be entitled as pay first and then use it. Each consumer has varying load demands thus depending on those load demands suitable amount of units (kWh) are recharged based on the pulses from the energy meter, microcontroller decrements the number of units of power consumption and displays the remaining available units on LCD display. When the count becomes zero the load is disconnected and it is reconnected when the consumer recharges the units of power. This system helps the consumers and power distribution companies to access the accurate and updated data from the energy meter by sending a message (SMS) to that energy meter, the information is being sent and received with the help of Global system for mobile communication (GSM) network. This energy meter gives the power cut information to the users with a buzzing sound. It also provides the feature of disconnection of power supply to the load whenever there occurs the power theft activities such as bypassing the power supply, this can be done from the distribution company by sending a message (SMS). This system mitigates the revenue losses of the distribution company a larger extent, which in turn helps distribution company to provide quality power to consumers.

Review of Control Strategies for Active Power Filters
Sneha Sanjay Nirmale, Sangeeta Mahaddalkar
Abstract:
In present days electricity has become non-separable from human life. Every sphere of human life is dependent on some or other equipment/machine in households, hospitals, industry etc. The consumers have different load patterns such as non-linear loads, switching etc. Such utility pattern results in harmonic generation and reactive power disturbances in the distribution system. The harmonics and reactive power cause a number of undesirable effects such as malfunction in sensitive equipment, over voltage by resonance, increased heat in conductor, harmonic voltage drop across the network impedance and thereby affects other customer loads connected at Point of Common Coupling (PCC). These undesirable effects are overcome to a great extent by deploying Active Power Filters (APF) at PCC. The power quality of a Distribution System can be improved by eliminating harmonics and disturbances due to reactive power. This is achieved by injecting required amount of compensating current to cancel out the harmonics and power disturbances and restore sinusoidal nature of voltage and current waveforms. This improves the power quality and helps protect the sensitive loads from malfunction thereby preventing damage. This paper presents a comprehensive review of Active Power filter configurations, their control strategies and the performance evaluation metrics such as Total Harmonic Distortion (THD) for different control strategies.
Keywords:
Point of Common Coupling (PCC), Active Power Filters (APF), Total Harmonic Distortion (THD).

Estimation of life and Reliability of Electronic Product
Ramesh E Patil, Jerald Leo, Govind R. Kunkolienkar
Abstract:
Presently, the market not only requires the fault free parts but also requires delivered product to work safely and failure free i.e. reliably. So for prevention of failure of product in between manufacturing stage to final usage stage, we need to do reliability as well as performance testing.Development in the electronic system i.e. VLSI and embedded system using component like FPGA, CPLD increases the reliability issue. So for reducing the reliability issue required to understand root causes of failure which causes failure in the field and further their minimization. Some traditional approaches like MIL-217 are used for reliability prediction but these type of approaches having some limitations like, it does not consider the load profiles, no provisions for root cause of component failure, the consideration of base failure rate and other unclear modifying factors.Prognostics and health management approach (PHM) consider the life cycle loading of the electronic system with its actual working conditions, which is the better tool for reliability predictions. This approach mainly relies on extensively Highly Accelerated Life Testing (HALT). This paper gives an idea about the reliability prediction approach.

Abstract:
Current Transformer is mainly used to convert high primary current in the power system to the level which can be handled by electromechanical or microprocessor based Relays and metering devices. The current transformer should be chosen correctly for a particular application considering the burden connected to the secondary, primary fault current and X/R ratio of the system. Over dimensioned or under dimensioned CT can cause mal-operation of relays. In this study, we have developed a windows application to check whether CT selected for particular application having certain burden is adequate or not. If in case the selected CT is not adequate then the application will suggest new CT design to avoid saturation. Proper Selection of CT is required for good protection scheme requirement.

Jayashree M, Dr. Nagesh Prabhu
Abstract:
This paper analyses the performance of a three phase grid tie inverter through simulation. The converter current controller is based on synchronous reference frame and d-q transformation which provides the reference voltage signal for the desired converter output voltage. The Sinusoidal Pulse Width Modulation generates firing pulses for six MOSFETs of the three phase full wave bridge converter and inturn regulates the active and reactive power flow of the converter. The dynamic variation in the voltage of DC source is neglected and hence DC voltage is held constant. The DC bus current is controlled by varying active current reference Iqref. Accordingly the DC source can absorb or supply active power by varying Iqref of the controller. The performance evaluation of three phase grid tie inverter for active power interaction while providing reactive power support is carried out in the present work.

Deekshitha C, K. Latha Shenoy
Abstract:
The demand of energy efficient lighting system is very essential in today's scenario. This is because the amount of energy consumption by lighting sources is approximately 20% of total electrical energy consumed in the world. In the recent years, LED lighting has emerged as a better energy efficient and eco-friendly solution for the residential and commercial lighting requirement. LED works on DC power and therefore it requires a device that can convert available AC power to DC power and regulate the current flowing through the LED during its operation. Thus to protect LED from line voltage fluctuations, a proper driver circuit is needed. In this paper the design of driver circuit for LED bulb with a synchronous buck converter is described. The simulation of driver circuit for both open loop and closed loop are done in MATLAB/SIMULINK software.

Detection and Classification of Ventricular Tachycardia Using SVM
Palimaru Aparna, Praveen Mirajkar, Raghavendra Prabhu
Abstract:
Ventricular Tachycardia is an abnormal heart rhythm that initiates in the ventricles. Non-sustained VTach lasts for few seconds and Sustained VTach lasts for few minutes or even hours. Sustained VTach is dangerous compared to Non-sustained VTach and if it is not treated, it often progresses to Ventricular Fibrillation. VTach is serious in people suffering with heart disease and is associated with more symptoms than other types of arrhythmia. Accurate prediction of Ventricular Tachycardia can be obtained by observing the changes in T wave, ST segment and QT interval which are the indicators for cardiac instability. In this paper, we present an algorithm that detects Ventricular Tachycardia by using morphological features of electrical signal of ventricles activity obtained from ECG. Classification of features is carried out by using Support Vector Machines (SVM). The proposed algorithm is tested on 22 records including Normal Sinus Rhythm and Ventricular Tachycardia which are collected from MIT-BIH Normal Sinus Rhythm database and CU Ventricular Tachyarrhythmia database respectively and satisfactory result is obtained as the 92.31% Specificity, 100% Sensitivity and 95.45% Accuracy is obtained.

Agricultural Robots: A Different Approach
Arnold Flavious D’souza, Ankith Rai, Aster Fernandes, Jolene Shaina Vas, Mr. Vaishak N.L
Abstract:
The main objective is to develop a model capable of performing multiple farming operations by incorporating a number of agricultural equipment into an autonomous robot. It contains a hopper, harvester, plougher, medicine sprinkler, fertilizer sprayer and chain drive mechanism. These components are controlled by microcontrollers and this is in turn operated by remote control.The approach is now to develop smarter machines that are intelligent enough to work in an unmodified or semi natural environment such as paddy or wheat fields. These machines do not have to be intelligent in the way we see people as intelligent but must exhibit sensible behaviour in recognised contexts. A single machine carrying out a variety of operations will greatly reduce costs of operations. Fertilizers are remotely dispersed which reduces the exposure of these chemicals to humans. Huge tracts of land can be cultivated in a short amount of time. Since the operations are automated, costs of employing humans are reduced.
