Design Studies and Aerodynamic Performance Analysis of Small Scale Horizontal Axis Wind Turbine Blade for Nano-Grid Applications
Journal of Automation and Systems Engineering
Wind energy, being easily accessible, environmentally friendly, and being cost effectively, has become the world's one of popular growing renewable energy sources of electricity generation. Among all of the wind turbines, Horizontal Axis Wind Turbine (HAWT) is considered as leading technology due to its high efficiency. However, to spread this technology to mankind it is needed to develop turbine in this way that people can use it individually and comfortably. This kind of thinking accelerates the advancement of integration of wind turbine with Nano grid concept. Although great progress has been achieved in the wind technology, there is still scope to reduce the cost and improve the performance of small-scale wind turbines. Moreover, low wind velocity should also need to be utilized properly to achieve saturated energy production. So, concentration is going to small scale wind. Small scale horizontal axis wind turbines (SSHAWT) provide a clean, prospective and viable option for energy supply. Moreover, SSHAWT can also be acted as one of the reliable power sources of Nano grid. To design efficient wind turbine it is required a smooth and continuous development process. The current study focused on aerodynamic design and performance analysis of small-scale horizontal axis wind turbine blade using the blade element momentum (BEM) method with most updated and corrected model. The effects of the design parameters of a small wind turbine such as the blade chord and twist angle distributions on power performance were also investigated. In this study, the pitch is fixed and speed is variable. Results show that the maximum coefficient of performance is .5089 at the Tip speed ratio 6.5 which is very indication in preliminary stage power prediction.
