1 Utilization Of Dstatcom In Matlab To Improvement Of Power Quality By Voltage Control 1 Mr.Ashenafi Selama, 2 Mr.Hagos Desta

This paper proposes another topology by Distribution Static Compensator utilizing Mat lab. This proposed strategy for control quality change accomplishes UPF which isn't conceivable in past strategies. Most extreme UPF is kept up, while managing voltage at the heap terminal, amid variance of load. Dstatcom illuminates Power quality issues by accomplishing PF rectification, consonant end, stack adjusting, and voltage control in light of the heap prerequisite.

2 An Active Power Filter Implemented With A Four-Leg Voltage Source Inverter Using A Predictive Control Scheme For RES 1.M. Veena Shree,2.Dr.V.Tamilselvan

The main aim of paper is to reduce the power quality problems in distribution system by using active filter. In this project PV Connected active type power filter is implemented. An active power filter consists of dc link capacitor, grid interfacing voltage source inverter, and filter. The dc voltage is supplied by photovoltaic system which is stored in capacitor. In this project we are using four leg voltage source inverter which converts DC to AC voltage. And the harmonics are eliminated by filter. Predictive controlling scheme use to operate or control the switches of voltage source inverter.All of these functions may be accomplished either individually or simultaneously. And we observed the simulation results by using MATLAB/SIMULINK

3 Integrated Inverter Or Converter Circuit For Motor Drives With Dualmode Control For Hybrid Electric Vehicle Applications 1.M Upender Reddy,2.P Pramada Kumari

In recent years, renewable energy sources such as photovoltaic (PV), wind, fuel cell, etc gain importance due to the limitations of conventional energy sources. Renewable energy sources play an important role in rural areas where the power transmission from conventional energy sources is difficult. Other advantages of renewable energy sources are clean, light and does not pollute atmosphere. In order to meet the required load demand, it is better to integrate the renewable energy sources with the load. Hybrid electric vehicles (HEVs) powered by electric machines and an internal combustion engine (ICE) are a promising mean of reducing emissions and fuel consumption without compromising vehicle functionality and driving performances. The proposed integrated circuit allows the permanent magnet synchronous motor to operate in motor mode or acts as boost inductors of the boost converter, and thereby boosting the output torque coupled to the same transmission system or dc-link voltage of the inverter connected to the output of the integrated circuit. Electric Motors, those are used for EV propulsion must have high efficiency for maximum utilization of the energy from batteries and/or fuel cells. Motor control algorithm for a dual power split system is proposed for hybrid electric vehicles (HEV). A new control technique for the proposed integrated circuit under boost converter mode is proposed to increase the efficiency. Since the light load performance is in recent focus of interest, appropriate algorithms to improve light load efficiency were implemented. The proposed control technique is to use interleaved control to significantly reduce the current ripple and thereby reducing the losses and thermal stress under heavy-load condition.  In order to evaluate performance of the control algorithm, HEV simulator is developed using MATLAB/ Simulink. Finally PV fed converter model is connected to induction motor and check the speed torque characteristics of IM. Matlab/Simulink model is developed and simulation results are presented.


Signature validation is an important biometric technique that aims to detect whether a given signature is forged or genuine. It is essential in preventing falsification of documents in numerous financial, legal, and other commercial settings. The human resources required to process and verify the innumerable transactions that occur on a daily basis is no longer an option. The automation of signature validation is not just to verify but to detect fraud. Automated Signature validation is a solution for efficient and fast validation of the signature that is a must to offer the best. There are multiple ways to automate the process of signature validation. The performance of traditional ways like Fuzzy models, Hidden Markov models are still far from optimal when we test the systems against skilled forgeries - signature forgeries that target a particular individual. Moreover it is a time and effort consuming process since the features need to be extracted after processing an image. The current best approach is to use Deep Learning. Our work aims to automate the process of signature validation by using Deep Convolutional Neural Networks. This reduces the need of feature extraction and once a modal is trained, we can supply the raw signatures as input which helps in obtaining fast and effective results.

5 Identification Of Faulted Distributed Line In An Ungrounded System For Symmetrical Faults 1.P Srinivas, 2.G Sandya Rani

Occurrence of symmetrical fault causes very low fault current, which causes difficulty in identifying the faulted line in an ungrounded system. Due to the complexity of distribution network, there is every necessity to clear the fault in very short span of time otherwise complete system will be affected. In order to overcome this difficulty, an ungrounded system is temporarily converted as a grounded system using thyristor based grounding. Due to this the magnitude of fault current will be increased, which helps in identifying the faulted line in distribution system. In this paper the methodology of identification of faulted line is presented using thyristor grounding method. The effectiveness of this method is verified by theoretical analysis and simulation results. This method is also applicable for resonant grounded and high resistance grounded systems.

6 Properties of Concrete with Egg Shell Powder and Silica Fume as Concrete Replacement 1.B. Sudhakar, 2. M. Priyanka, 3.P. Madhavi

Concrete is a material that is being put to extensive use all over the world in the construction of the vast majority of buildings, bridges, and other kinds of construction. At the moment, the whole building and construction sector is actively engaged in the hunt for an acceptable and practical product that has not yet been used. If it were to be commercially successful, this product would reduce the amount of cement that is employed, which would, in turn, result in a reduction in the cost of building structures overall. This kind of alternative material includes things like egg shell powder and silica fume, for example. Because egg shells have historically been considered worthless and have finally been shown to have detrimental impacts on the environment, the great majority of egg shells that have been thrown away are able to be disposed of in landfills without first needing to undergo any form of pretreatment. Because of this, a suitable alternative is required in order to deal with the waste in an ecologically friendly way. The goal of this investigation research is to determine whether or noteggshell powder and silica fume might be successfully included in cement in a limited capacity as additional components. In addition to the substitution of eggshell powder for 2.5 percent, 5 percent, and 7.5 percent of the total weight of cement, silica fume is being replaced by egg shell powder in the amounts of 5 percent, 10 percent, and 15 percent of the overall weight. The strength of concrete made from eggshells was evaluated in a number of different ways, including split tensile strength, compressive strength, and flexural strength. The outcomes of these examinations are shown in the table that is located below. It was found that adding eggshell powder and silica fume to the concrete caused the strength of the concrete to rise, and in the end, a comparison was made between the increased strengths of eggshell and silica fume in concrete.
