PROJECT TITLE Single phase continuous power Supply selector from 3

phase power

SUPERVISOR Dr M.Sivakumar

LEVEL Diploma

Objectives:

Most industrial and commercial processes are dependent on electrical power. In case of single

phase load connected in three phase system, power interruptions in one phase or two phases, at

that time manually change from one phase to other phase often results in wasted time. Moreover,

Machine damage sometimes occurs because of human errors. These can cause significant financial

losses. This project presents the design and construction of an automatic phase change-over switch

that switches electrical power supply from one phase to other phase in the event of a power cut in

any phase. This system uses an electric control circuit involving rectifier unit, integrated circuits

and relay.

PROJECT TITLE Solar Cell Voltage controller

SUPERVISOR Dr. VimalaKeerthy

LEVEL DIPLOMA

Objectives:

Solar cell is an electrical device that converts the energy of light directly into electricity. Light

shining on the solar cell produces both current and voltage to generate electric power. The Solar

Panel Voltage Regulator acts as a blocking diode when the battery voltage is greater than the

solar array voltage. There will be no reverse current flow. It draws no current from the battery.

This project aims to construct a charge controller circuit that will alert the low voltage charging

of battery and also protects battery from high voltage charging. The circuit operation is mainly

based on the operation of PNP and NPN transistors. The circuit operation is tested on bread board.

PROJECT TITLE Automatic Light control circuit

SUPERVISOR S.Gobi mohan

LEVEL DIPLOMA

Objectives:

Automatic Light Control System is a simple yet powerful concept, which uses transistor as a

switch. By using this system, manual works are 100% removed. It automatically switches ON

lights when the sunlight goes below the visible region of our eyes. This is done by a sensor called

Light Dependent Resistor (LDR) which senses the light actually like our eyes. It automatically

switches OFF lights whenever the sunlight comes, visible to our eyes.By using this system energy

consumption is also reduced because nowadays the manually operated street lights are not

switched off even the sunlight comes and also switched on earlier before sunset. In this project, no

need of manual operation like ON time and OFF time setting.

PROJECT TITLE Watchdog for your mains

SUPERVISOR Mr.Srinivasan

LEVEL DIPLOMA

It is like a Dobermann or a Bull Terrier though it guards not your personal belongings but your

‘mains supply’. The circuit is based on an ‘opto-coupled resistor’ that is used to trigger a timer

based integrated circuit. This circuit will be appreciated particularly by the users of personal

computers and deep freezers, as it not only indicates the failure of mains supply through an alarm

but also triggers on a relay for operating any externally connected appliance such as a generator.

It also indicates the exact time duration for which the supply had failed.

PROJECT TITLE INTELLIGENT ROBOT FOR PV PANEL CLEANING

SUPERVISOR Dr.B. Bensujin

LEVEL ADV. DIPLOMA

Globally it can be understood a fast change in technology and everything modified quite faster with billions

of inventions and especially in the field of Electrical & Electronics. We decided to choose a topic which is

related to advance technology and our area of specialization. Our topic is robotic based system to make

the man’s life easier. As the robot is useful in our life and it can used in everywhere. So as a project group

in we decided to design a robot this can clean the solar panels effectively. In this project we focus on a

technique based on signaling pathway unmanned vehicles (UV) to clean the PV panels when a dust is

formed. The dust formed in different locations of solar panel are identified by a dust sensor and the amount

of dust formed is calculated by the control system. The control system enables the robot to move to the

exact location by determining the shortest path. This project aims to work in two different modes: 1. Auto

and 2. Manual. In the automatic mode following operations are performed. The dust sensor is used to

determine the intensity of dust and accordingly the robot will moves to the specific location and clean the

dust. The robot will take the shortest path to reach the identified location and after cleaning it will move the

nearest lay by. At the same time the output power from the PV panel is calculated based on the sun intensity

and if it is found to be less the entire PV panel will be cleaned.

PWM SPEED CONTROL OF SINGLE PHASE INDUCTION MOTOR

SUPERVISOR Mr. Gujarathi P. K.

LEVEL Adv. DIPLOMA

Lot of attention is there in speed control of three phase induction motor due to its high volume use. However

irrespective of its use in many application of fractional horse power single phase induction motors from

household to industry, there is less attention in terms of speed control and power saving. In this project

simulation of a speed control scheme of a single-phase induction motor (SPIM) is carried out in

MATLAB/Simulink. A pulse width modulated (PWM) control technique is carried out using amplitude and

frequency control. The simulations result shows that wide range of speed control is possible using both

frequency and amplitude control. However at higher amplitude above 0.7, the range of speed control of not

linear and more change is required for small change in speed. The speed control method can save power

and this can be implemented as a future work.

SIMULATION OF HIGH VOLTAGE GAIN BOOST DC/DC CONVERTER WITH VOLTAGE DOUBLER CHARACTERISTIC

SUPERVISOR Dr.P.Radika

LEVEL Adv. DIPLOMA

In the recent years, the demand of renewable energy systems like photovoltaic systems, wind, etc. has

increased significantly due to the shortage of fossil fuels. As these renewable systems generate dc power

at low voltage level, high gain dc-dc step up converters are getting more and more attentions. This project

presents the performance of a high voltage gain DC/DC boost converter. It is suitable for the renewable

energy systems to raise the small dc voltage into a high voltage. Compared with the conventional boost

converter the proposed converter has double the voltage gain in the range of duty cycle 0.5 to 1. The

performance of the circuit is verified by using MATLAB/SIMULINK. The results obtained shows that the

proposed converter has a high voltage gain with efficiency than conventional boost converter.

PROJECT TITLE Enhancement of Voltage Quality in Isolated Power Systems

SUPERVISOR Prasad.C

LEVEL Adv.DIPLOMA

Power Electronics and Advanced Control technologies have made it possible to mitigate power

quality problems and maintain the operation of sensitive loads. Among power system disturbances,

voltage sags, swells and harmonics are some of the severe problems to the sensitive loads. The

series compensation method is best suited to protect such loads against those disturbances. The

use of a series compensator (SC) to improve power quality is an isolated power system is

investigated. The role of the compensator is not only to mitigate the effects of voltage sag or swell,

but also to reduce the harmonic distortions. The modeling and simulation of the proposed series

compensator was implemented in Matlab Simulink work space. Simulation results showed that the

pro-posed series compensator was efficient in mitigating voltage disturbances and thus im-prove

the power quality of the isolated power system.

PROJECT TITLE Power Factor Improvement of Induction Motor by Using

SUPERVISOR Dr.G.Sugumaran

LEVEL Adv. DIPLOMA

For industrial and mining applications, 3phase AC induction motors are the prime movers for the vast

majority of machines. It has been estimated that 70% to 80% of all electricity in the world is consumed by

these motors. At no load induction motor has very low power factor. It improves at increasing load from no

load to full load. Power factor correction is achieved by the addition of capacitors in parallel with the

connected motor circuits and can be applied at the starter, or applied at the switchboard or distribution

panel.

In this project work, Matlab based simulation is carried out for three phase 5 HP induction motor under

different loading conditions with and without capacitor. Performance characteristics are obtained for

Induction motor and comparison are given in detail.

PROJECT TITLE GREEN SMART IRRIGATION SYSTEM

SUPERVISOR Dr.M.Sivakumar

LEVEL Adv.DIPLOMA

In recent days, agriculture field farmers are facing many problems

in watering their plants to keep their crops green particularly in

summer season. In other hand, the solar PV panels have proven

through a period of time that they are unfailing to produce adequate

electricity directly from solar radiation. And the demand for water in any

irrigation system varies throughout the complete year in any particular area.

This paper proposes the use of solar power for irrigation purposes to

overcome these drawbacks. Solar powered water pumping systems can be

the most perfect and suitable solution for rural locations which are grid

isolated countries where the amount of solar radiation is very high.

Solar powered water pumping systems (SPPS) can be used to supply to

basic needs of the community like providing drinking water,

water for irrigation etc. without the need for any kind of fuel or wide-ranging

maintenance.

PROJECT TITLE Simulation of Electric Vehicle

SUPERVISOR Gujarathi P. K.

LEVEL Bachelor

With increasing oil price and mounting environment concerns, cleaner and sustainable energy solutions

have been demanded. At present transportation constitutes a large portion of the energy consumed and

pollution is created. In our project we will study and simulate Electric Vehicle as a solution of above

problems. The specifications of TESLA S electric car model will be used for simulation. However it is

powered by Li- ion battery only which has high energy density and low power density. To improve

performance of power density, the Ultracapacitor is investigated and combination is proposed. However

due to practical challenges, more investigations are required to implement the proposed circuit, hence in

this work simulation for performance analysis of Tesla S car is carried out by MATLAB/ SIMULINK software.

SUPERVISOR Pandimadevi.G

LEVEL Bachelor

Continues Stirred Tank Reactor (CSTR) is an important subject in chemical process and offering a diverse

range of researches in the area of the chemical and control engineering. Various control approaches have

been applied on CSTR to control its parameters.The temperature of the continuous stirred tank reactor

(CSTR) is controlled in three Configurations (feedback, feed forward and cascade).In Phase 1, we

designed the control system in Feedback and feed forward control configuration. In Phase 2, we de-

veloped the Cascade controller for CSTR and analyzed about the stability of all the con-trol configurations.

For each configuration a stability analysis is made using (Bode, Nyquist and Root-locus) criterions. A

selection for recommended control design has been taken on the output response of the systems as well

as the stability for each system

PROJECT TITLE A Comparative Analysis of Transient Stability Improvement Using Power System Stabilizer (PSS) and Static VAR Compensator (SVC)

SUPERVISOR Mr. Muthukumar Selvakkannu

LEVEL Bachelor

The objective of this project is to compare the performance of a conventional power system stabilizer and Static VAR

compensator to improve the transient stability of power system. Power system stabilizer is a conventional method

which is used to make the system oscillation free. The performance of this system is now compared with one of

FACTS devices used Static VAR compensator Transient stability is one of the most important stability of the power

system. The loss of Transient stability is due to overloading of some of the lines (or due to sever line fault) as a

consequence of tripping off of the other lines after fault or heavy loss of loads. The simulated SVC shows how the

oscillations are damped out with PSS and SVC controller. Performance of both PSS and SVC are compared. In this

semester we develops our project to (4-machine & 6-bus) and we can get different graphs by using MATLAB software.
