INTRODUCTION

Today, the world is progressing at quite a fast rate with the use

of the conventional sources of energy. The two major

disadvantages of using them are the environmental pollution

created by its use and its limited quantity. On the other hand

the Non-conventional sources of energy are available in plenty,

free of cost and pollution free. So its the time to think for

switching on to the Non-conventional sources and restrict the

use of conventional sources of energy Many types of clean and renewable energy sources can be

used in the production of electrical energy.


4/22

These include solar energy, wind

energy, wave energy,

hydroelectricity, biomass energy,

energy from wastes, tidal power,

and geothermal energy.

All of these energy sources have

environmental benefits over the

use of fossil fuels.

Our paper deals with the Energy

conservation Technique which is a

combination of two Non-

conventional sources of energy,

i.e. Solar and Wind Energy.


5/22

SOLAR ENERGY

Four-fifths of the suns energy falls

on the oceans and drives the water

cycle. Evaporation from the sea

causes rain to fall on the land,resulting in the global hydropower

resource. The remaining fifth of the

suns energy falls on the land and is

still about 2,000 times greater than

total world energy demand.

The three main technologies that

have been developed to capture this

energy are Passive Solar, Solar

Thermal, and Photovoltaic modules.


6/22

SOLAR ENERGY(DISADVANTAGES)

Apart from its advantages few Disadvantages are as follows:-

Solar power is not always completely predictable because it depends on the

amount of sunlight that reaches the Earth at any given time. This precludessolar power generation during the night when sunlight does not reach the

part of the Earth in which the cell is located and limits solar power

generation when cloud cover scatters portions of the electromagnetic

spectrum.

Some forms of solar power are not currently cost competitive. A

Photovoltaic power station is expensive to build, about 10% efficient, and the

energy payback time is large of the order of five years.


7/22

WIND ENERGY

The uneven heating of the earths

surface by the sun causes wind. This

heat is absorbed by the ground or water

and is then transferred into the air,

causing differences in air temperature,

density and pressure. These differencesthen create forces that push the air

around. Like the water that flows in the

river.

The wind contains energy that can be

converted into electricity using windturbines. Currently, more than 20,000

wind turbines are used for generating

electricity around the world.

Wind power projects can also be very

stimulating for local economics.


8/22

WIND ENERGY(DISADVANTAGES)

As Solar Energy Wind Energy too has some Disadvantages.

Wind power is irregular in many locations, because consistent

wind is needed to ensure continuous power generation

Commercial generation requires a wind farm over large areas

having an effect on scenery

The effect of large scale wind farms on the climate is unknown.

Thus to overcome from the disadvantages of these energy

techniques we should combine these two techniques and By

this we can achieve more efficient and environment friendly

energy source throughout year.

HYBRID SYSTEM(HSWPS)

Hybrid Systems - Utility Connected with Battery Backup. A combination of

the above systems, these applications have the advantages of both. They

are connected to the utility grid in case the weather is insufficient for the

solar or wind system, but they also have batteries to store electricity in case

the utility grid goes down as well. The design and installation of these

systems is more complicated and expensive, but they are the most effective

in providing constant, reliable electricity.

The System Include

PV Array Wind Turbine

Aero-Wind Generator Solar Controller

Wind Controller Battery Bank

Inverter Loads

PV Array:-

A number of PV panels connected in

series and/or in parallel giving a DC

output out of the incident irradiance.

Orientation and tilt of these panels areimportant design parameters, as well

as shading from surrounding

obstructions.

Wind Turbine:-Which is installed on top of a tall

tower, collects kinetic energy from the

wind and converts it to electricity that is

compatible with a homes electrical

system.


11/22


Aero-Wind Generator:-This is one of the main components in

this system and converts kinetic energy

of wind into electrical energy in thewind into mechanical energy. An

electric generator is coupled to the

propeller shaft directly, this propeller in

turn rotates rotor of the electric

generator and in turn generates DC

electricity. The output from the windgenerator varies as per the wind speed.

Wind electricity for decentralized

system or hybrid generation of

electricity using other energy sources

as wind regimes for localized small grid

systems or battery charging..


12/22


Solar Controller And Wind Controller:-

Controls battery bank charge and

discharge reasonable and safety.

Battery bank:

There can be a single battery or multiple batteries connected together to

create essentially one large battery of the

required voltage and amp-hour capacity. In

some ways the battery configuration and

capacity are the most important electrical

power decision to make, and a wise choice

can help guarantee a steady supply of

electrical power as well as a system that is

simple to operate and maintain.


13/22


Inverter:-A power converter that inverts the

DC power from the panels into ACpower.

.

Loads:-

Stands for the network connectedappliances in the building that are fed

from the inverter (AC loads), or from

the battery bank(DC loads).

FEATURES(HSWPS)

Designed for easy to operate ,servicing and maintenance

where requiredMost Eco-friendly & clean source of power.

No pollution and no recurring fuel costs, Highly

reliable and consistent power supply.

Long life span for SPV modules & Modular design

Very few moving parts-negligible maintenance required

Increases public safety and aids in providing a safe

working environment in areas where mains power is

risky


19/22

APPLICATIONS(HSWPS)

Ideal for cell phone recipient stations.

Farm houses, Guesthouses, Hospitals, Hotels,

Laboratories and R&D centres

Remote and Rural village electrification.

Residential colonies and Apartments general Lighting.

Street Lighting.Transmissions and communication Tower and many more

applications.


20/22

CONCLUSION

Because the seasonal profiles of the wind and solar resources are

somewhat complementary in some reason, combination of wind and solar

perform better than either wind or solar alone

Under the circumstance of power failure this hybrid system keeps the

continuity of supply without producing any noise pollution, dislike any other

power generating equipment i.e. D.G. Set with noisy operation.

High Efficiency than Individual systems.

Since the longer pay back time of investing renewable energy system, little

firms are interested in investing the renewable system.
