Introduction Non conventional energy generation using wind.

Wind energy generated by two different turbine. Vertical axis wind turbine(VAWT)

Horizontal axis wind turbine(HAWT) In our project we use the Vertical axis wind

turbine(VAWT).

Energy generated by VAWT using in street lightingfor energy saving purpose and it is controlled bymicrocontroller.

Wind Energy Wind energy is the kinetic energy of air in motion.E=1/2mv2 Wind power is the conversion of wind energy into a

useful form of energy, such as using wind turbine tomake electricity.

We can not convert all of the power in the wind toMechanical (then electrical) power

Losses caused by Some of the wind goes around (not through) the hoop You cant slow the outgoing wind to zero velocity

Frictional losses from high velocity wind

Type of Wind TurbineMany types of turbines exist today and their designsare usually inclined towards one of the two

categories.

1. Horizontal-axis wind turbines (HAWTs)

2. vertical-axis wind turbines(VAWTs)

As the name pertains, each turbine is distinguished bythe orientation of their rotor shafts.

VAWTs are typically

developed only for the

urban deployment

Changes in wind direction

have no negative effects on

this type of turbine because

it does not need to be

positioned into the wind

direction.

The propeller-type rotor is

mounted on a horizontal

axis.

HAWTs are sensitive to the

changes in wind direction

and turbulence which havea negative effect on

performance due to the

required repositioning of

the turbine into the windflow

Working of VAWT VAWT are a type of wind turbine

where the main rotor shaft is set

vertically and the main components

are located at the base of the turbine.

VAWT can catch the wind from all

direction and at lower wind speed

than horizontal axis ones.

If direction of blades is change than

dynamo also generate electricity

because dynamo does not depends

on direction of rotation.

Advantage of VAWT Can accept changes of wind direction with no

problem.

Generator can be on the ground for more easy

access, rather than up in the air. Generally begin rotating at lower speeds

Lower susceptibility to cross-wind

Application


11/13

Street LightingWhen vehicle runs in theroad then wind will comethen blade will rotate andelectric energy generate and

stored in battery If vehicle rotate right toleft or left to right thenthere are no effect on VAWT

During night this energyused as street lighting.

Microcontroller Street light can controlled by microcontroller

Using light dependent resister(LDR) to detect the

intensity of light

LDR sends the signal to the microcontroller and

microcontroller adjust intensity of light.
