    (2017-08-24T07:00:31Z) ARUN, KUMAR S; JAIPRAKASH, P M; SATHISH, M; PADMA, S M
    This paper deals with the solar photovoltaic (SPV) array fed water- pumping system using a DC-DC converter as an intermediate Inverter and a permanent magnet brushless DC (BLDC) motor to drive a centrifugal water pump. Among the different types of DC-DC converters, an elementary Boost converter is selected in order to extract the maximum power available from the SPV array and for safe starting of BLDC motor. The elementary DC-DC Boost converter with reduced components and single semiconductor switch has inherent features of reducing the ripples in its output current and possessing a boundless region for maximum power point tracking (MPPT). The electronically commutated BLDC motor is used with a voltage source inverter (VSI) operated at fundamental frequency switching thus avoiding the high frequency switching losses resulting in a high efficiency of the system. The SPV array is designed such that the power at rated DC voltage is supplied to the BLDC motor-pump under standard test condition and maximum switch utilization of DC-DC Boost converter is achieved which results in efficiency improvement of the converter. Performances at various operating conditions such as starting, dynamic and steady state behavior are analyzed and suitability of the proposed system is demonstrated using MATLAB/Simulink based simulation 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

    Switching of Multiple Sources using AT89C51ED2 Microcontroller
    (2017-08-24T05:30:51Z) SHUBHAM, YADAV; BHUPINDER, SINGH; SANTHOSH, SHRIVATSAV
    India is currently the fifth largest producer and consumer of electricity in the world but continuity and reliability still remains a vision unfulfilled. India’s state utility losses over the past 5 years has been GDP. Though India has doubled its power generation in the past decade by adding 85GW of capacity, it’s inefficient ways of transmission and distribution leads to losses of over 30GW. Results of this study shows that relying on renewable sources instead of only the state utilities for individual homes can save up to 40% of energy bills and also helps for a sustainable future by reducing consumption of conventional resources such as fossil fuels and other hazardous resources which harms the environment. For ensuring a continuous and reliable supply, every individual space using power can use switching of multiple sources of renewable energy along with the power supply from utilities which is being carried out in this project. The switching of these multiple sources is done using a 32-pin microcontroller as the main component. This system has the potential to be a successful alternative to meet with the countries energy demands but at the same time can reduce losses to improve the country’s economy.

    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.

    (2017-08-24T05:11:11Z) LAXMI, PRIYA NAYAK; NIKHITA, VENUGOPAL; PRABHAT; PRAKASH, KUMAR CHOUDHARY
    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.

    Variable Electronic Speed Governor
    (2017-08-24T05:08:22Z) DIPESH, BHUSHAN; DEEPSHIKHA, SINGH; NILKANTA, DE; RAHUL, KUMAR
    Intelligent instruments are used in every part of our lives. As the days of manned driving are getting extremely numbered, so are those of traffic jams, dangerous and rough drivers and more importantly, accidents. According to Mr Willie D. Jones in the IEEE SPECTRUM magazine (September 2001), a person dies in a car crash every second. Automation of the driving control of vehicles is one of the most vital needs of the hour. Bengaluru and many cities of the world have been experiencing an increase in road traffic accidents much of which can be attributed to human errors such as over speeding. The project put forth a theory which proposes that any given area of a city, town or village can be divided in to defined speed zones which are classified according to different speed ranges. At regular intervals, a transmitter is placed, as set for a particular area by regulating body such as the BCTP (Bengaluru City Traffic Police). Transmitter transmits a message signal at carrier frequency, indicating the upper limit speed value of that area into which the vehicle is entering at that moment, to the receiver which gives the message as an input to a pre-programmed MICROCONTROLLER embedded within the automobile which compares the speed of the vehicle measured by a sensor at the hind wheel with the maximum allowable speed and automatically regulates the speed of the vehicle by controlling the fuel flow by sending pulse signals to a servo motor and thus keeping the speed of the vehicle in constant check. The entire system is a variable electronic speed governor, small in size and easy to assemble onto an existing vehicle without disturbing its present arrangement.

    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.

    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 .

    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.

    (2017-08-23T11:00:31Z) SANDEEP, SHARMA B V; SUNIL, KUMAR T; MOHAMMED, MUBASHEER Z; SUNIL, KUMAR J H
    Generation of energy takes places at a resource rich geographical locations and transferred to energy demand centres. These demand points are too far from generating stations and hence there is a need for research and development in how efficiently can the generated power be transferred to distant places for its usage. Its Transmission & Distribution loss accounts for23.65%, the highest and lowest being Korea, 4.10%. India’s economic rise, the demand for energy has grown at an average of 3.6% per annum over the past 30 years.

    (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.

    (2017-08-23T09:34:05Z) PRIYANKA, L.N; REDDY, LAKSMI. K; CHANDANA, .M; YASHODHARE, .Y
    Wireless transfer has been employed since long time in telecommunications. Radio waves, cellular transmissions and Internet WiFi are only a few examples of wireless transmission. Recently, there’s been a growing interest towards the experimentation of a deeply challenging idea for wireless applications, supplying electronic devices without cords. The development, application and spread of this new concept could make consumers life enormously easier. As the usage of the portable electronic devices is increasing, the demand for longer battery life is also increasing. These batteries need to be recharged or replaced periodically. It is a hassle to charge or change the battery after a while, especially when there is no power outlet around. Therefore, our team is inspired to design a wireless battery charger. This wireless battery charger is expected to eliminate all the hassles with today's battery technology. Wireless power transfer through the use of strongly coupled magnetic resonances works very well for efficient mid range power transfer in dynamic environments compared with other power technologies. Mobile phones, as many other portable electronic devices powered by electrical energy, generally use electro-chemical Li-ion batteries to store energy. These batteries are light and can come in many different shapes and sizes, being easily adapted to provide the required autonomy to our everyday portable electronics. However, they exhibit lengthy charging cycles and a short life span. Super capacitors can be a better option for the conventional batteries. Super capacitors act like any other kind of capacitor, only they can store tremendous amounts of energy. Super capacitors are able to attain greater energy densities while still maintaining the characteristic high power density of conventional capacitors

    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.

    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.
