VOLTAGE PROFILE IMPROVEMENT AND POWER LOSS REDUCTION IN POWER DISTRIBUTION SYSTEMS USING PARTICLE SWARM OPTIMIZATION by Mandeep Kaur 

Abstract : The power distribution systems are becoming bulky day by day due to the increase in electricity demand; therefore, it becomes necessary to maintain the power distribution systems so that they can meet the customer demand. Power losses are the major concern in the electrical power system. Uptill now, many techniques are available for the reduction of these losses but capacitors are considered as a simple and most powerful device. If capacitor is utilized in a wise way, we may obtain maximum benefits like voltage profile improvement, power loss reduction, the annual cost reduction due to losses and enhancement in the net annual savings. In this thesis work, an artificial intelligence technique known as Particle Swarm Optimization have been used for the allocation of capacitors. The most sensitive buses which can lead to maximum benefits are selected on the basis of their loss sensitivity factors and cost function. After the selection of these buses, capacitors are placed on them. These two methodologies are performed on the basis of an algorithm which consists of a sequence of steps and henceforth, it is tested on IEEE 39-bus system. The algorithm is implemented in the form of MATLAB coding which results into improved voltage profile and efficient loss reduction. Particle swarm optimization is an iterative method, hence it will goes through effective number of iterations in order to get the global best result.

DESIGN AND OPTIMIZATION OF RADAR ABSORBING MATERIAL WITH THE HELP OF RESISTOR FSS by Ravinderjit Kaur

Abstract

RADAR absorption materials (RAMs) and coatings have been widely used in stealth technology since World War II. Stealth refers to the ability to evade from the detection from any kind of radar detection. Radar absorbing materials have found a significant importance in today’s stealthy technologies to make the combat aircrafts or drones electromagnetically invisible to the radar detectors. So a combat aircraft can be useful in the war field only if it is not detectable by sensors and moreover the capacity load it can hold to carry maximum armed forces and ammunitions. Therefore, numerous research works have been done to pursue a high-performance absorber to solve the electromagnetic pollution problem. Earlier different types of paints were used to coat the surfaces of the aircrafts, also known as black body paints. But paint not only used to make the aircraft heavier but would also incur unnecessary costs. With the advancement it has been invented that instead of painting the surface, the surface itself be made up of radar absorbing material. Various designs were also proposed in this regard but of hardly any use, as they also were not able to reduce detection to great extent. Then with further advancement it has been invented that the frequency selective surface embedded in the layers of radar absorbing material has better absorption than the normal ones. But

till now the proposed different geometric structures or the use of lumped elements in the material so far has one or the other limitation. So this work has been proposed to find the best trade off between the maximum absorption bandwidth and minimum material thickness with the use of particle swarm optimization and also compares the results of with and without lumped elements. The proposed comparison and results of optimization are in good agreement.

IMPLEMENTATION OF SAFETY MANAGEMENT IN INDIAN INDUSTRIES : A CASE STUDY) by Sushil Kumar 

Abstract

The purpose of the study was to reduce or eliminate the accidents during production processes in “Shivalik Bimetal Controls Limited”. Which was on higher side and wasting lot of money of the organization, In general observation it is noticed that the company has been facing so many issues in their production (like; accidents, absenteeism, low production rate, improper handling) due to the lack of proper safety measures. The study uses Root Cause Problem Solving (RCPS) technique and starts with the collection phase, followed by the analysis phase and ends with the solution phase. Supporting data are presented using a Pareto Chart to highlight accidents in order to be more focused for elimination or reduction. The Q.C. tool is performed to analyse the cause of accidents, to express and implement corrective actions. The application of the Q.C tools in a manufacturing industry (Shivalik Bimetal Controls Limited) provides a fact-based and organised approach to the problem identification. Corrective action had enhanced the production and reduced the accidents from 35% to 12.6% which was the 70% of the total accidents and it helped to increase the productivity of the organization. The study was also proved that industrial safety training with sound understanding of manufacturing coupled with possible solutions using safety management tools. This corrective action was not only able to reduce accidents, but also upgraded the product quality.

ANALYSIS OF LIQUEFACTION POTENTIAL SOIL USING SPT DATA by Arveen Kaur 

Abstract

Liquefaction is the result of undrained failure of saturated, highly contractive (loose sand). When this phenomenon occurs, there are drastic changes to structures which results in loss of life and property. The factors which affect the liquefaction potential are relative density, depth of water table, grain size distribution of soil, confining pressure, peak pulsating stress, amplitude and frequency of shaking, distance from earthquake. The liquefaction hazards are commonly associated with saturated or silty sands having low plasticity and density. In the present study, the SPT data is collected from various resources majorly from Testing & Consultancy cell, Civil engineering department, GNDEC, Ludhiana. Out of the available sites, total 80 Sites borehole data was taken and was selected for further work. Then this selected data was analysed using Liqit Software and same data is calculated on spreadsheets by NCEER Youd et. al methods. Also, the comparison has been made on the basis of factor of safety from Liqit and spreadsheet values. The comparison was represented by graphs for each site. The major work of the thesis was to plot the liquefaction map on GRASS GIS software. The maps were generated depth wise on GRASS GIS software. This gives an edge over one single value of depth. Hence, consecutive depths were chosen to give a broad view of the work done. The detailed analysis of how to generate the Graph is also mentioned and given in Annexures. Basic overview of Liqit software is also given in annexure. This thesis will cover as much region as possible for each district in Punjab. Some sites data was discarded due to their very close proximity with other sites

APPLICATION OF VALUE ENGINEERING: A CASE STUDY OF COUPLER FOR BEDDED VALVES by Kulpreet Singh 

Abstract

It is becoming essential to develop new alternatives with lesser cost,but giving same or better performance in current competitive environment. Every industry strives hard to meet the requirements of customers and to reduce production cost. Value engineering is a scientific tool for improving value potential, reducing cost while meeting the functional utility. In present work Value Engineering Job Plan (VEJP) was used to reduce the qualitative cost of manufacturing of coupler. The study was carried out at Sir Valves, Jalandhar. The poor value areas were highlighted and worked upon. Changes in design were proposed leading to 4.18 per cent of savings.
