In this system, we make utilisation of vertical axis Wind turbine for energy generation. Vertical Axis Wind Turbine is which is run by energy of air. It comprises of vertical axis Wind mill, DC motor,12v battery ,dc inverter and transformer .
Because of increase in demand of electricity ,relying on fossil fuel based energy will pose threat to the human kind,as the availability is limite. Hence the focus is on renewable energy sources like wind, solar, tidal. There has been a surge in these energy uses ,and it will go on and on as the time goes . Wind energy is a good source to use as renewable energy, before 21st century wind was primarily use to pump water from Wells to feilds of crops ,but last 20 years cost of wind energy has been dropped by 80% turning it into the most affordable form of clean energy.
II. WORKING METHODOLOGY
In this we have used 12v DC generator with a maximum speed of 2000rpm . The generator converts mechanical energy to electrical energy. As wind strikes the blade it creates pressure zones ,these pressure zones is reason to rotate the blade of turbine. Output of generator goes to the controller,which controls the energy and send it to the battery. It also prevents overcharging and increases the efficiency of overall mechanism.
III. DESCRIPTION OF HARDWARE
DC 12v , 2000rpm generator. Converts mechanical energy to electrical energy produced by wind .wind strikes the blade the rotator rotates and simultaneously the generator also rotates.
The vertical axis turbine is successfully developed and gives constant supply. The main purpose and application of this model is to use vaccum and pressure created by high speed winds.
