Abstract:Â
The main objective of this work is to compare the two proposed configurations of vertical axis wind turbine with and without load condition. It involves fabrication of two proposed configuration of same capacity of 150 W and testing rpm for the model, for various wind velocity and comparing power obtained. Performance of VAWT such as coefficient of power is flow around the blade. A great degree of design versatility in vertical axis turbine gives the economically viable energy solution for remote area, by analysing a drawback such as poor self-start, low initial torque and low coefficient of power should be overcome for majority of wind generation in vertical axis type. Vertical axis turbine has various configurations in nature. However, there are certain advantages and disadvantages with different configurations. Horizontal axis turbine is used in wind power generation, VAWT due to lower efficiency they are not used majorly in power generation but VAWT has certain advantages over HAWT such as operational independence of wind direction owing to its vertical axis operation it does not require yaw mechanism, simplicity in construction and maintenance. A detailed review on various configurations available till now and the work done on the each configuration must be studied. The various parameters that must be analysed thoroughly for the performance improvement include type of blade, number of blade and blade angle, tip-speed ratio and forces acting on the blade with respect to the wind velocity and altitude of wind turbine.
