Monitoring Maize Irrigation System Using Arm Microcontroller LPC2148
T. Gayathri, R. Boomidevi, S. Ragul
Abstract:
In this paper, the system is designed for monitoring the growing status of the Maize plant continuously and updates the information to the agriculturist using ARM Microcontroller LPC2148.This project will makes ease the work of the farmer in cultivated land through the usage of different kind of sensors. The temperature sensor LM35 will find the intensity of heat present in the soil. Humidity sensor will determines the amount of water vapor present in a gas that can be a mixture, such as air, or a pure gas, such as nitrogen or argon.Water level sensor will find the water level in the corn field. The PH sensor will measure the alkalinity or acidity level in the soil. Soil pH is very important because it has such a strong influence on how well your crops will grow. Soil Moisture sensor can be used to test the moisture of soil, when the soil is having water shortage, the module output is at high level; else the output is at low level. By using this sensor one can automatically water the Maize plant by Switching ON the DC MotorAll the updates of farmland are sending to the farmer through GSM and display in the LCD screen. With this less cost and energy utilization, WSN is a hopeful method for harvesting the Maize crop and also improves the quality of the corn crop and reduces the usage of pesticides, thereby increasing the overall profits for the farmers.

Voltage Sag Compensation Scheme for DVR using Space Vector Modulation
A. S. Kamaraja, P. Srinivasan, J. Velmurugan
Abstract:
This paper deals with improving the voltage quality of loads from voltage sags using dynamic voltage restorer (DVR). The higher active requirement associated with pulse width modulation (PWM) has caused a substantial rise in size and cost. The existing control strategies either mitigate the pulse width modulation or improve the utilization of dc link energy reducing the amplitude of injected voltage. In this paper on enhanced sag compensation strategy is proposed it mitigate the overall sag compensation time. An analytical study shows that the proposed method significantly increases the DVR support time compared with existing PWM method. This enhancement can also be seen as a considerable reduction in dc link capacitor sixe for new installation. The performance of the proposed method is evaluated using simulation study and finally verified experimentally on a small prototype model.

Energy Storage System for Electric Vehicle
S. Mohan, Anitha .A, Dr. R. Deepa
Abstract:
In this paper an alternative energy storage system in the drive train of a hybrid electric vehicle is investigated. In particular, it concentrates on the potential reduction of the stresses of the battery when electrochemical capacitors, a.k.a super capacitors, are added as high power energy storage. Different control strategies are evaluated and an estimation of the performance is given. In order to verify the simulation results, a downscaled HEV drive train consisting of NiMH batteries, electrochemical capacitors, a DC/DC converter and an external load, is built and tested. The results show a significantly reduction in battery stresses and a good agreement between the models used in simulations and the laboratory system. Finally, a weight optimization of such a system is briefly discussed.

Integrated Hybrid Standalone System With Bess And Power Converters For Renewable Energy Application
Sharmila, T. Kokilavani
Abstract:
To have sustainable growth and social progress, it is necessary to meet the energy need by utilizing the renewable energy sources like wind, hydro, co-generation etc. The need to integrate the Non-renewable energy and wind energy into power system is to make it possible to minimize the environmental impact on conventional plant. The integration of renewable energy into existing power system presents a technical challenges and that requires consideration of voltage regulation, stability, power quality problems. In this proposed scheme the Static compensator (STATCOM) is connected at a point of common coupling to mitigate the power quality issues in wind energy system. The project also presents a novel control strategy for achieving maximum benefits from the grid-interfacing inverter when installed in 3-phase distribution systems. The effectiveness of STATCOM scheme relives the main supply source from the reactive power demand of the load and the induction generator.

Solution for CEED using Hybrid (Firefly-De) Algorithm
S. Hareesh, F. Abdul Kadhar, V. Lokeshraj, U. Revanth and B. Sheik Abdulla
Abstract:
This project develops efficient algorithms by using firefly and differential evolution algorithm to minimize Economic Dispatch, NOx Emission Dispatch and Combined Economic and Emission Dispatch problems in thermal power plant. The thermal power plants pollute air, soil and water. Due to this, the present energy production processes are not ecologically clean. The combination of fossil fuels gives rise to particulate materials and gaseous pollutants apart from discharge of heat to water courses. The three principal gaseous pollutants, namely carbon-dioxide, oxides of sulfur and nitrogen cause detrimental effects on human beings. This harmful ecological effects caused by the emission of particulate and gaseous pollutants can be reduced by adequate distribution of load between the plants of a power system. But, this leads to a noticeable increase in the operating cost of the plants. For successful operation of the system subject to ecological and environmental constraints, algorithms have been proposed for minimum cost, minimum NOx emission and combined economic and emission dispatches. These are based upon quadratic type objective function and the solution gives the optimal dispatch directly. In the present work, a price penalty factor is introduced which blends the emission cost with normal fuel cost. This avoids the use of two classes of dispatching and the need to switch over between them.

Solar Power Based Single Phase Seven Level Invertor
S. Shanmugavalli, N. Vinothini
Abstract:
In low power renewable systems, a single-phase inverter is usually adopted. This project deals with a Seven-Level inverter topology that follows this trend. A review of the state of the art of the Seven-Level topologies and a theoretical power loss comparison with the proposed solution is realized. The proposed inverter architecture is based on a full-bridge topology with two additional power switches and two diodes connected to the midpoint of the dc link. Since the two added levels are obtained by the discharge of the two capacitors of the dc link, the balancing of the midpoint voltage is obtained with a specific pulse width modulation (PWM) strategy. Simulation and experimental results show the effectiveness of the solution.

K. Suresh, Dr. R. Arulmozhiyal, B. Sathyaseelan
Abstract:
Proportional Integral Derivative (PID) controller is the most recommended controller in industries that does not require precise analytical model of the system to be controlled. This paper presents a Design, Analysis and Modeling of PID (Proportional -Integral-Derivative) controller based on FPGA (Field-Programmable Gate Arrays) for Synchronous Multiphase DC-DC Converters in Automotive Applications. Mat lab Simulink is used for the PID controller design to generate a set of coefficients associated with the desired controller characteristics. This simulation platform also integrates tools for a future implementation of the PID controller embedded in a FPGA controller. The main contribution of this work is to implementation of a PID controller that can be used independently of the number of phases of the converter, making it suitable to be applied in a wide range of high power applications. This controller has been designed having in mind, the goal of developing a real-time FPGA-based controller, so the complexity has been reduced to a minimum. Hybrid vehicles, aerospace, naval industry, process control, manufacturing, robotics and automation and transpiration system power systems can also benefit from the development of this controller.

A Novel Approach for Soil Testing using Embedded System
D. Rupa, B. Arunmohan Raj, K. Gowtham, R. Raashmi, Dr. R. Gopalakrishnan
Abstract:
At present many analytical laboratories that provide a chemical soil testing service, some are woefully inadequate testing only for phosphorus, potassium, pH and salinity and ignoring all other nutrients. Others can be very comprehensive but the results badly presented. This makes it difficult for the farmer in particular to make any sense out of his own soil test and puts his decisions regarding fertilizer firmly in the minds of the "experts" who are also often the manufacturers/sellers of particular types of fertilizer. Our main objective is to develop a testing system which can be used for soil analysis, which in term helps the farmers to grow and produce the proper crop that can be a feedback to the farmers to implement "precision agriculture". The System measures Nitrogen, Potassium, Phosphorous and PH of soil. In the system, nitrate and phosphorous ISE are used to measure concentration of N and K nutrient of soil.

Optimisation of Two Area Power System Using Differential Evaluation Algorithm
D. Lakshmi, R. Zahira
Abstract:
Load Frequency Control (LFC) is used to adjust the real power generation based on the load changes. When the real power demand is increased than the supply then the output frequency of the generator will reduce from the rated value. The difference in frequency between actual and rated reference value is called change in frequency. This change in frequency is used to adjust the steam supply and thereby the real power generation. Proportional (P) and Integral (I) controllers are used to control this LFC. To find the best value of this PI gain constants needs an intelligent approach is required. In this project intelligent algorithm Differential Evolution (DE) is used to find gain constant of PI controller. The advantage of the proposed controller is that it can handle system non-linearity and at the same time proposed controller is faster than the conventional controllers. The proposed controller is modeled for an interconnected two area power system as a simulation model in MATLAB/SIMULINK. The performance of intelligent algorithms based controllers are compared with the conventional Proportional Integral (PI) controller. The effectiveness of the proposed controller in increasing the damping of local and inter area modes of oscillation is demonstrated in a two area interconnected power system. The result shows that this controller has good dynamic response and at the same time faster than the conventional controller.

Conversion of Plastic Wastes into Hydrocarbon Fuels
R. Boopathy Pradeep, R. Balakrishnan, A. Dinesh, S. Saravanan
Abstract:
The present rate of economic growth is unstable without fossil fuel crude oil, natural gas, coal. So the mankind has to rely on the renewable energy resources like biomass, hydropower, geothermal energy, wind energy, solar energy, nuclear energy, etc. On the other hand, sustainable waste management is the important for sustainable development. Plastic wastes are one of the fastest grown materials because of its application and low cost. Plastic is the term refers to the synthetic or non-synthetic amorphous solids like polyethylene, polystyrene, polyvinyl chloride and phenol formaldehyde. These are the materials which are widely used to make industrial products. Due to raise in increase in plastic waste causes serious effects in environment and has a great impact on social conditions. But, this can be controlled by recycling of plastic wastes. The solution for recycling of non-recyclable plastic into liquid hydrocarbons is degradation. This can be done by pyrolysis and liquid hydrocarbon fuels can be obtained like petrol, diesel, kerosene, etc. Conversion of plastic waste into fossil fuel will reduce the dependence on the fossil fuels. This process can ensure 100% eco-friendly and nothing is left behind the environment

Solar Energy Collection using Spherical Sun Power Generater
M. Devaraj, S. Shanmuga Priyan
Abstract:
This paper suggests a new concept of solar collection that prints the solar cells directly onto a spherical surface, or a balloon. It can be used for substitution of the depleting of fossil fuels in thermal applications and electricity generation through thermal route. Usually the concentrated solar power means focusing the sun's energy from a large area into a smaller area, which generates a lot of heat that can be used to produce electricity. Solar power is the conversion of sunlight into electricity, either directly using photovoltaic (PV), or indirectly using concentrated solar power (CSP). Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaic convert light into an electric current using the photovoltaic effect.

Multi-port Power Electric Interface for Renewable Energy Sources
M. Devaraj, P. Kirupanantham, K. Jayakumar
Abstract:
In order to accommodate increasing energy demand from"more electrified" domestic and vehicular applications, simultaneous use of various renewable sources are encouraged. Multiple converters are commonly adopted to process the renewable power as a distributed power system (DPS). However, due to the loose structure of DPS, reliability and load/source regulation will degrade as compared to an integrated converter system. This paper presents the concept of Multi-port Power Electronic Interface (MPEI) for renewable energy sources. With a unified converter topology and highly integrated digital control system, MPEI possesses the inherent capability of both source disturbance rejection and load dynamics regulation. MPEI identification, modeling and design are treated in a systematic manner in this paper. Power stages and digital control system will be implemented for a five-port MPEI in this paper. Experimental results will be presented to prove the feasibility of system design methodology.

A Novel Multilevel Inverter Topology with Reduced Switches using Fuzzy Controller
R. Venkatesh, Dr. S. Senthil Kumar
Abstract:
Multilevel inverter has become popular in recent years for high power applications. Their major drawbacks are complexity, required more numbers of power devices and complex control circuitry. This paper proposes fuzzy logic controller based a new multilevel inverter topology using an H bridge output stage with three bidirectional auxiliary switch. In the proposed circuit configuration the inverter produces nine levels including a zero. The new topology produces a significant reduction in the number of power devices and capacitors required to implement a multilevel output when compared to the conventional MLIs. The Total Harmonic Distortions generated by multilevel inverter can greatly reduced by fuzzy logic control scheme. In this proposed work the harmonics distortion was reduced by using Fuzzy Logic Control scheme, which increases the performance of the multilevel inverter.

Wireless E-Voting System
M. Lavanya, S. Divya Bharathi, R. Elavarasi, T. Hariharan
Abstract:
In the era of technology, the voting machine, which is present today, is highly unsecured. The present electronic voting machine is not intelligent that is it cannot determine the person came for the voting is eligible or not. That mean the whole control is kept in the hand of voting in charge officer. One more risk with the present voting machine is that anybody can increase the vote count, since the count is present in the machine itself. In proposed machine that is "Global Wireless E-Voting"machine is made intelligent which can determine the eligibility of the voter by scanning the eye pattern. Here there is no chance of increasing the vote count of machine. Even in case of damage to voting machine there will not be harm to continuity of the election process. The overall concept of "Wireless E-Voting System" is explained.

Ungrounded Aircraft Power System Protection
Kabilarmani B, Lalith Kumar V, Jamir Ahamathu J, T. Hariharan
Abstract:
Recent Studies are been made to implement the 270V DC/ Hybrid 115Vac electric Power Generating and distribution systems technology used in the small military aircrafts to domestic aircrafts. The studies are being made to design and build a high-efficiency, high-reliability, fault tolerant, low-weight, low-cost hybrid aircraft electrical system for future domestic airplanes. The system is distinguished as "Grounded" and "Un-grounded" depending upon whether the neutral point of the generator is connected to ground or not. The analysis indicate an Electrical Power generating system(EPGS) distribution system weight savings due to two wires for 270-Vdc rather than three or four wires for the typical 115V,400Hz ac system. The feeders, bus lengths, and wire sizes were chosen to be representative of what would be used in modern More Electric Aircraft (MEA).

Review of Renewable Energy Resources
M. Priyadharshini, R. Saravanan, S. Ramya
Abstract:
The electricity requirements of the world including India are increasing at alarming rate and the power demand has been running ahead of supply. Other conventional resources, presently being used for generation of electrical energy, may not be either sufficient or suitable to keep pace with ever increasing demand of the electrical energy of the world. Also generation of electrical power by cold based steam power plant or nuclear power plants causes pollution, which is likely to be more acute in future due to large generating capacity on one side and greater awareness of the people in this respect. The recent severe energy crisis has forced the world to develop new and alternative methods of power generation, which could not be adopted so far due to various reasons. The non-conventional methods of power generation may be such as solar energy, wind power, hydro-electric energy, biomass, hydrogen and fuel cells, geo-thermal power etc. This paper elucidates about different non-conventional energy sources like solar, wind, hydroelectric, biomass, geothermal etc,
