The Electrical Distribution Board is the heart of the train system which feeds electrical supply into subsidiary circuits through relays & contactors while providing a protective fuse or circuit breaker for each circuit, in a common enclosure. The objectives to be covered under this project are :(1) To understand the Start-up and Shut down sequence of metro train.(2) To study the interlocks with other systems involved in Start-up and Shut down of metro train.(3) To simulate the control logic for the operation of Pantograph, Door systems and Train shuttle between stations.
Demand Side Management
(2017-08-23T09:30:16Z) MOHAMMED, RIYAZ; K.R, KALYAN; PAVITRA, N
Demand side management (DSM) is an important technique for demand response (DR) system in electrical networks. The DSM techniques traditionally have focused on minimizing electricity consumption or peak load. More recent work reveals that users wish to reduce their electricity bills without sacrificing user convenience. Hence, waiting time has been introduced to reflect the user comfort for the DSM. Residents usually preferred that finish their work as soon as possible than less waiting time. These techniques have not taken previous usage pattern consideration, thus have been limited for use in home appliances. In this paper, we propose a system architecture and an algorithm for DSM referred to as user-friendly DSM (DSM) using ICT. The DSM is based on time-varying price information considering the following three-fold factors: electricity bill, usage pattern, and rebound peak load. Our proposed algorithm is divided into two steps. In the first step, we formulate the objective function based on electricity bill and usage pattern, and we minimize the electricity bill and maximize the usage similarity. Then, as the second step, we apply a load balancing algorithm to avoid blackout and to minimize rebound peak load. Our algorithm is tested in a real data from KPTCL and experimental results validate the proposed DSM scheme shifts the operation to off-peak times and consequently leads to significant electricity consumption and user satisfaction ratio by using GSM technology.

(2017-08-23T09:18:42Z) APARNA J, J; CHANDANA, C S; GAUTAM, S; RUPAK, KUMAR SHARMA
Elastomeric bearings are used in helicopter tail rotor for transfer of control to the blade via pitch control. These bearings are subjected to complex dynamic load during operation. In order to check the functionality of these bearings, a specially designed test facility is necessary. Complex dynamic load should be simulated on this test rig to study the performance. The existing system is a mechanical closed loop test system consisting of power pack, manifolds, actuator, controller and data recording system. This project deals with design and development of suitable closed loop electrical system for simulation of loads experienced by the bearing. The electrical system consists of motor with drive controls, sensors and equipments for data recording. This electric motor provides an oscillatory motion of about ±25˚ at the rate of 50˚ per minute. The present concept eliminates the extensive maintenance required for the mechanical system. The prototype model is done by using a stepper motor and an appropriate closed loop computer controlled system.

(2017-08-23T08:57:26Z) AKASH, V.K; KASUMALLA, NAGENDRA; MUKUL, R
In modern industrial field, the requirement for monitoring and controlling system is one of the most important criteria for minimizing the power consumption. The Internet of Things (IOT) is an emerging key technology for future industries and everyday lives of people, where a series of battery operated sensors, actuators, and smart objects are connected to the Internet to provide services such as mobile healthcare, intelligent transport system, environmental monitoring, etc. With the development of infrastructure such as high speed transport and smart cities, more and more safety infrastructure needs to be monitored. In the meantime, a lot of old infrastructure such as pipelines, bridges and building needs to be monitored for lifecycle assessment, improving safety and security. New infrastructure is required for low cost, reliable monitoring. Here we are creating an application which receives all the data from various hardware devices and not only display‘s the information in real-time which is accessible from anywhere in the world but allows for automatic control and regulation of the system based on specifications pre-set by the user. This helps to maximize efficiency, safety and security while reducing the need for human interference.
LVDC Distribution System for Energy Efficiency using Micro Grid
(2017-08-23T12:17:24Z) LAXMI, KUMARI; ERANNA; P, MALLIKARJUN; SATHISH, M
It is well known that the Low-Voltage DC (LVDC) distribution system is a promising topology as a future smart distribution system due to its high efficiency and reliability. The focus of the paper is on the development trends and the dependencies of the LVDC distribution system energy efficiency. Future LVDC system will be able to improve the energy efficiency of distribution networks. Moreover energy efficiency is depends on components such converters and infrastructures such as energy storage systems involved in LVDC distribution system, so that more efficient converters and storage systems are used to make LVDC distribution system more efficient. Nowadays, with renewable, energy is often produced in DC and then converted to AC for transmission and distribution purpose. A large majority of electrical and electronic devices for their functioning needs DC without conversion into AC. The conversion process involves from DC to AC and then again to DC. This generates some extra energy losses that could be avoided. A DC grid avoids some conversion steps and results in lower material costs and higher energy efficiency, reducing conversion losses. But Some DC to DC conversions would still be required.

Magnetic levitation, maglev or magnetic suspension is a method by which an object is suspended with magnetic fields. Magnetic pressure is used to counteract the effects of the gravitational force and any other acceleration. This project dwells on the implementation of an alternate configuration of a wind turbine for power generation purposes. Using the effects of magnetic repulsion, savonius shaped wind turbine blades will be fitted on a rod for stability during rotation and suspended on magnets. Power will then be generated with an axial flux generator, which incorporates the use of permanent magnets and a set of coils. Maglev wind mills have several advantages over conventional wind mills. This new application of maglev technology being used in a vertical axis wind mill is also very advantageous over the conventional horizontal axis wind mill.

Electrical machines are the back bone of electrical engineering and play a vital role in industry. For high rating values which cannot be practically supplied to the machine, through this program one can observe the values for high ratings and also different machines with different specifications. To get different internal and external characteristics of these machines in the lab, systematic results and graph can be obtained using Matlab programs. Electrical Machines can be analysed for any values for the experiment. Developing apps for Matlab is on the rise nowadays. Matlab has become the gold standard and user- friendly. There are many calculations in machines numerical problems which are time consuming, especially the problems which have iterations. There are various types of machines present in e lect r ica l engineering on which va r ious expe r iments a re per formed and the output va lue s are calculated and the necessary graph is plotted.

Unified power quality conditioner (UPQC) is one modern device which deals with voltage and current imperfections simultaneously. In this paper, an attempt has been made to model the UPQC for voltage and current compensation with the help of two different control schemes. The current and voltage harmonics as well as voltage sag and swells compensation are shown.
Photovoltaic Array Based Power Generation System using Nine Level Inverter
(2017-08-24T05:05:35Z) AYUSH, SEN; PRIYANKA; ABHIJEET, SINHA; ANAND, RAJ
Now days, there is a large scarcity of electric energy in our world and at the same time the demand is also increased. Many distributed power system have been developed to meet this high demand by using renewable energy resources like solar systems, wind energy systems and other distributed energy resources. Photovoltaic technology currently being the most popular solar power technology gives rise to a reliable DC power generation source. The solar energy is becoming more important because it produces less pollution. The cost of fossil fuel is increasing, while the cost of solar arrays is decreasing. Recently small capacity distributed power generation systems using photovoltaic energy may be widely used in residential applications. Photovoltaic system is interconnected to a grid through two power stages, dc-dc converter and dc-ac converter. Power electronic converters, especially dc/ac PWM converters have been extending their range of use in industry because they provide reduced energy consumption, better system efficiency, improved quality of product, good maintenance and so on. The output voltage of a PV array is low; a dc–dc power converter is used in a solar photovoltaic system to boost the output voltage. It should be insure that there is no waste of the energy generated by the PV array because of the important of power conversion efficiency of the power conversion interface. There are mainly two power losses such as conduction losses and switching losses. Conduction loss is due to the use of active devices, and the switching loss is proportional to the voltage changes and the current changes for every switching and switching frequency. For a multilevel inverter, the voltage change in each switching operation is reduced for improving its power conversion efficiency and the switching stress of the active devices.
Remote Control System of HYDEL Power Plant
(2017-08-23T09:38:19Z) RUBINI, .J; SAHITHI, .N; PALLAVI, .N
Water and energy are essential elements of humanity’s life and civilization, and hydro power relates both. Hydro power is the world’s most widely used form of renewable energy. It produces around 20 percent of the world’s electric power. It allows clean, sustainable and emission free power production. Hydro power is uniquely flexible, since in our country the most of the hydro power plants are either manual or under supervisory control based. It does not provide the efficient safety for the hydro power plant and real- time data and reports of parameters of power plant. This project is designed to integrate automation and provide real-time remote operation, analyze and monitoring the parameter like water level at a hydel power plant. It also provides the safety indications and alarming system for the plant. This is achieved by placing sensors at different points in the hydro power plant and using BC-547 Transistor to provide a water level parameter and also acts as an interface between the sensing arrangements. This system can be enhanced by integrating GSM technology, by which an SMS is delivered to the concerned person or chief of power plant, regarding the status of generation and any other required information. We can also control some of the operations through SMS. It can also be upgraded with process graphics for prediction and detection of any changes in hydro power plant.
Self Sourced Energy Efficient Streetlights
(2017-08-24T05:14:02Z) REEJABHATTACHARYA; JAYA, KUMARI; SIJO, M. VARGHESE
Man in his lifetime, uses energy in one form or the other. In fact whatever happens in nature, results, out of the conversion of energy in one form or the other. The blowing of the wind, the formation of the clouds and the flow of water are a few examples that stand testimony to this fact. The extensive usage of energy has resulted in an energy crisis, and there is a need to develop methods of optimal utilization, which will not only ease the crisis but also preserve the environment. Energy conservation is the cheapest new source of energy. This paper attempts to show how energy can be tapped and used at a commonly used system, the road power generation. Road Power Generation (RPG) is one of the most recent power generation concepts. This device converts the kinetic energy of the vehicles into electric energy by installing moving plate on the road, it takes the stroke motion of the vehicles and converts it to the rotary motion by crank mechanism and it generates the electricity. This paper also explains clearly, the working principle of the designed system, its practical implementation, and its advantages. The utilization of energy is an indication of the growth of a nation. One might conclude that to be materially rich and prosperous, a human being needs to consume more and more energy. And this paper is best source of energy that we get in day to day life. To reduce power consumption due to street lighting, we propose replacing conventional power consuming High Pressure Sodium Lamps and metal Halide lamps with LED lamps which consume much less power. We also propose employing LED light dimming by modifying the light intensity based on the traffic conditions on the road. Most of the dimming systems currently deployed on the streets use computerized and remotely controlled wireless monitoring systems which suffer from complexity, high cost and a response that is dependent on the network data transfer speed.
Sepic Based Led Driver
(2017-08-24T05:01:55Z) ARTHI, M; MEGHA, A.T; POOJA, KUMARI; SRUTHY, V KUMAR
A novel high-power-factor single-stage single-switch light-emitting diodes (LEDs) driver for street lighting system is proposed in this paper. By integrating the single- ended primary- inductor converter (SEPIC) power factor correction circuit and Class- E resonant dc/dc converter, the proposed converter exhibits extreme simplicity and high reliability, as there is only one active power switch. The LED driver could achieve nearly a unit power factor by operating the SEPIC circuit at discontinuous conduction mode. With careful parameters design of a single Class-E resonant converter, the proposed converter can achieve soft-switching characteristics, which could significantly reduce the switching losses and greatly improve the system efficiency. Operational principle, analytical results, and design considerations at 100 kHz are presented, and a 100-W laboratory prototype is proposed to verify the theoretical analysis, whose efficiency is as high as 91.2% in full-load state under 110 V .

(2017-08-23T08:24:55Z) ADARSHA, GAYAN; SUDIP, MONDAL; RAJ KUMAR, BASU; SAMIK, HAZRA
A single-inductor dual-output (SIDO) buck-boost power factor correction (PFC) converter operating in critical conduction mode is proposed in this paper. By multiplexing a single inductor, each output of the SIDO buck-boost converter can be regulated independently. Compared with a conventional two-stage multiple-output converter, the SIDO buck-boost PFC converter benefits from significant overall cost saving, small size, and light weight. Moreover, the efficiency of the SIDO buck-boost PFC converter can be improved due to single-stage power conversion. The control strategy and characteristics of the proposed converter are analyzed. The efficiency, power factor, total harmonic distortion, and output accuracy are verified using the experimental results.

(2017-08-24T06:30:15Z) Y., HEMALATHA; SHAIK, MOHAMMED IDRIS; VARUN, M.MITTAL; SHUBHAM, S.MAGDUM
Electricity theft is responsible for economic problems for the electric utility due to revenue loss caused by electricity consumers that are not paying for it. In this report, a Smart Power Theft Detection System (SPTDS) with instantaneous SMS alert is proposed. The set up contains an Smart Statistical Meter (SSM), placed at the transformer end and or on Electric High Pole. It communicates with the various consumer meters as well as linked with it through wireless communication i.e, WiMax. It monitors and records the readings from the consumer end and sets it as a reference value. Whenever this reference value is exceeded, unmetered load (illegal) is detected and this information is sent to Utility Company through WiMax channel for further action. The algorithm for this proposed project is modelled in MATLAB/SIMULINK and satisfactory results are expected at the end

(2017-08-23T08:54:07Z) DEEP, CHAKRABORTY; PETER, DK VAIPHEI; GANESH, GOUDA G; PRASHANTH, KUMAR M
The goal of this project is to design a lighting system with the aim of energy saving and autonomous operations. One of the most important challenges faced by consumer electronics in these days is energy saving. Artificial luminaries account for a great part of day to day total energy consumption. This emphasizes the need for an energy efficient lighting system. We have designed a control solution for energy efficient lighting system- ‘The Smart Lighting’. In this proposed system, we have used different sensors for automatically controlling the switching-dimming action of LED lamps and speed variations of fan. In addition to this, we have used manual kit for controlling the LED lamp intensity and fan speed variation which makes it user friendly. Moreover, this lighting system is powered from a battery which is powered from a PV-panel employing solar charging. Solar charging helps the panel to charge the battery to its maximum level for reliable performance of this lighting system. The Smart Lighting provides comfort, convenience and are capable to become the lighting solution for future generation. Recently Green issue has been raised as a burning topic, especially in Engineering Field, where most of the researcher and engineer are involving themselves in finding a solution to reduce the energy usage at the same time increasing their product efficiency. Smart system is an autonomous operations where detects the environment changes through sensors and acts to correct the offset caused by the environment. Moreover, the systems continually perform from time to time to reach the optimal result that is pre-defined in the system.
