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 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.

PROJECT TITLE
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.

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.

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.
