DESIGN AND FABRICATION OF HORIZONTAL AND VERTICAL WIND TURBINE

Wind energy is one of the major forms of renewable energy resources found abundantly which is widely used as an alternate energy. Wind power is sustainable and the production of electricity using wind energy is increasing day by day due to lack of availability of fossil fuels. The wind energy can be converted into electricity by using a wind turbine, which is of two types-vertical axis wind turbine (VAWT) and horizontal axis wind turbine (HAWT). The vertical axis wind turbine is mainly used for domestic applications where the volume of production is low and efficiency is optimal while the horizontal axis wind turbine is widely for larger volume of production and requires huge investment and efficiency is also higher. In this project, an effort has been made to combine the vertical axis wind turbine (VAWT) and horizontal axis wind turbine (HAWT) on the same tower, which in turn reduces the space requirements. The combined vertical and horizontal axis wind turbine also reduces the cost for larger volume of electricity generation. A prototype of the horizontal and vertical axis wind turbine has been designed and fabricated. It is observed that around the premises of G Pullaiah College of Engineering and technology , the winds are strong & persistent. This situation motivated to select the present work. A system to store the energy generated from the windmill by using a dynamo is designed and developed. The system is tested for its power coefficient at different situations which resulted in a satisfactory output
