---VIGNESH.S
Nowadays energy plays an important role in our day to day life. The method
we brought to you is to save energy and can use those saved energy to many
purpose. This has been done purposely to reduce the consumption of
electricity as every where there is shortage of current supply, that too mainly
in hot cities like CHENNAI. This is done majorly to benefit schools and
colleges.
This can also be implemented in houses. If this system is implemented in the
schools and colleges.
, there will be no shortage of current.
The basic materials needed in this system is :-
(1)2 tires
(2)2 Dynamos

(3)Rechargeable battery
(4)Inverter
These material-models are subject to change according to the offered rooms.

A dynamo (from the Greek word dynamis; meaning power), originally anothername for an electrical generator, generally means a generator that produces directcurrent with the use of a commutator. Dynamos were the first electrical generatorscapable of delivering power for industry, and the foundation upon which manyother later electric-power conversion devices were based, including the electricmotor, the alternating-current alternator, and the rotary converter. Today, thesimpler alternator dominates large scale power generation, for efficiency,reliability and cost reasons. A dynamo has the disadvantages of a mechanicalcommutator. Also, converting alternating to direct current using power rectificationdevices (hollow state or more recently solid state) is effective and usually
economic.
The word still has some regional usage as a replacement for the word generator. Asmall electrical generator built into the hub of a bicycle wheel to power lights iscalled a Hub dynamo, although these are invariably AC devices.

A rechargeable battery or storage battery is a group of one or moreelectrochemical cells. They are known as secondary cells because theirelectrochemical reactions are electrically reversible. Rechargeable batteries comein many different shapes and sizes, ranging anything from a button cell tomegawatt systems connected to stabilize an electrical distribution network. Severaldifferent combinations of chemicals are commonly used, including: lead-acid,nickel cadmium (NiCd), nickel metal hydride (NiMH), lithium ion (Li-ion), andlithium ion polymer(Li-ion polymer).
Rechargeable batteries have lower total cost of use and environmental impact thandisposable batteries. Some rechargeable battery types are available in the samesizes as disposable types. Rechargeable batteries have higher initial cost, but can
be recharged very cheaply and used many times.

An inverter is an electrical device that converts direct current (DC) toalternating current (AC)[1];the converted AC can be at any required voltage and frequency with the use of appropriatetransformers, switching, and control circuits.
Solid-state inverters have no moving parts and are used in a wide range of applications, fromsmall switching power supplies in computers, to large electric utilityhigh-voltage direct currentapplications that transport bulk power. Inverters are commonly used to supply AC power fromDC sources such as solar panels orbatteries.
There are two main types of inverter. The output of a modified sine wave inverter is similar to asquare wave output except that the output goes to zero volts for a time before switching positiveor negative. It is simple and low cost (~$0.10USD/Watt) and is compatible with most electronicdevices, except for sensitive or specialized equipment, for example certainlaser printers. A puresine wave inverter produces a nearly perfect sine wave output (

center hub(because when only one dynamo is kept, there will be an imbalance
to the fan , where destruction takes place) is labeled with a rust remover
paper or some ruff paper so that the tyre gets grip without slipping from the
coated fan . These dynamo are in hold with the stand which is sealed in the
wall . The dynamo is coupled with the rechargeable battery.
The battery is coupled with the inverter and then connected to the switch
board.
WORKING:
When the fan is switched ON the fan starts rotating , simultaneously the
tyres connected with the dynamo placed touching with the centre part of the
fan hub also starts rotating at the most same speed of the fan .
Due to this rotation of the tyre, the energy is generated and these generated
energies are saved in the rechargeable battery . The saved energy is sent to the
inverter where the energy is converted to AC current as a backup.
When the current is stopped from the main supply point , the AC supply
which is converted from the inverter is directly connected to the switch board
that helps in connecting to the fans and tube lights. In this process the backup
power generated is same as that we get from the main supply. The energy is
again conserved as this will be a cyclic process.
APPLICATION:
The energy produced by this system will be like a cyclic closed loop process
where ample power can be saved. No interruption in lecture/seminar, No
tension of power failure, un disturbed output and saves overhead charges if
we use for certain time even power is available which will extend healthy life
of the rechargeable batteries and inverter circuits
This can also be implemented in educational institution (schools & collages),
hospital, banks and service organisation to serve the public where more public
involvement.
ADVANTAGE:
1. Assured un-interrupted power supply.
8/3/2019 Energy Conservation System1

2. Low initial cost.
3. Simple mechanism.
4. Availability for essential equipment.
5. Easy to establish.
6. Renewable never ending power source.
More electricity can be saved as there will be no shortage of current in any places
3. This can also be implemented in houses.
4. The system that are already being used in house, schools and collages has the inverters where there will be current
supply only for a particular period of time. After that ,energy used cant be regained. But the system proposed here will
be profitable because the supply of current from inverter is reused by using dynamo, so that this will be cyclic and a
never ending process.
DISADVANTAGE:
1. Odd looking may overcome by suitable modifications of casing.
2. Initial cost in setting of this process will be more.
3. There will some loss of energy during conversion from energy to AC current

The Electricity plays a vital role in the current day to day life. We can say without electricity day to day
work will be stalled. So the Hospitals, Offices, firms and Education Institutions badly in need of
electricity and backup source for the same in the case of electricity failure. Most of the organisations to
resolve this problem going for Diesel Generator or the Inverter for the short term requirement. But these
diesel generator will produce environment pollution as well as sound pollution.
To handle such a critical situation, the RENEWABLE ENERGY SYTEM' will cater the requirement.
This system will give un-interrupted power supply to meet the emergency as well as normal situation.

Electric Power
Power, originating at a power generating plant, is distributed to residential,
commercial, and industrial customers through various transmission lines and
substations.
Residential Applications
Power, generated at a power plant, then stepped up to a high transmission voltage
is brought to a local substation. Here, it is stepped down to a lower distribution
voltage. When it reaches its final destination at a residential customer, it is stepped
down to 240 volts. Only single-phase power is used in a typical residential
application.

Principle of AC Generators:
AC generators operate on the theory of electromagnetic induction. This
simply means that when conductors are movedthrough a magnetic field a voltage is
induced into theconductors. A basic generator consists of a magnetic field, an
armature, slip rings, brushes, and some type of resistive load. An armature is any
number of conductive wires (conductors)wound in loops which rotate through the
magnetic field. For simplicity, one loop is shown.
If the rotation of the AC generator were tracked through a complete revolution of
360, it could be seen that during the first quarter of a revolution voltage wouldincrease until it reached a maximum positive value at 90. Voltage would decrease
during the second quarter of a revolution until it reached zero at 180. During the
third quarter of a revolution, voltage would increase in the opposite direction until it
reached a maximum negative value at 270. During the last quarter of a revolution,
voltage would decrease until it reached zero at 360. This is one complete cycle or
one complete alternation between positive and negative. If the armature of the AC
8/3/2019 Energy Conservation System1

generator were rotated 3600 times per minute (RPM) we would get 60 cycles of
voltage per second, or 60 hertz.
