Introduction

Aero dynamic turbines converts the kinetic energy of the wind to mechanical energy.

A wind turbine obtains power input by converting the force of the wind into a torque (turning force) acting on the rotor blades.

The amount of energy which the wind transfers to the rotor depends on the density of the air, the rotor area, and the wind speed.

The output of the generator is connected to the load or the power grid.

The design of the wind turbine is an integral part which decide the efficiency.

Measurement of Wind Speed Velocity

In prior stage of the wind turbine project has basic requirement is to measure the wind speed and the velocity.

Testo is the German equipment to measure the wind and all other parameters is use for any of our wind project for assurance of wind speed.

PERMANENT MAGNET BRUSHLESS GENERATOR

Permanent magnet generator is same as that of shunt motor withthe difference thatthere is permanent magnet instead of stationary field winding for producingthe required magnetic flux.

Since this is Brushless and Commutator is absent it requires practically no maintenance.

The Life of this type of motor is longer compared to others.

Project Components :

BLADE

Blade design is made of aluminum and epoxy resin.

Above material are used for our blades.

Aero Dynamic blade made of carbon fiber is light weight. Has a razor sharp edge which cut through the wind and makes it virtually silent.

Conclusion

We had done market survey on Vertical Axis Wind Turbine(VAWT).

We justify that how to VAWT works and produces electricity through block diagram.

Also, we understood how to design blade and measurement of wind speed with use of anemometer.

Thank You…
