2023ICERD8-C07 -- Investigations on Intelligent Wind Turbine System to Improve the Power Output

Improving wind turbine efficiency is crucial in today's electrical industry, and wind turbine regulation is a significant challenge. Wind turbines, for example, are ideal for remote regions and may be used in small towns because they require less wiring than steam power plants. However, some conventional wind turbines were poorly constructed, lacking attention to technological feasibility. This study integrates mechanical, electrical, and computer engineering skills to create a complex model for manufacturing a wind turbine. The fundamental goal of this research is to bridge the gap between wind turbine efficiency and Betz's limit. With that suggestion, an intelligent mechanism is devised and implemented utilizing an Arduino control system to autonomously control the wind turbine's face based on the flow direction. The chosen airfoil for this design is the NACA 4412, with a relatively moderate Reynolds number that varies between 2.9 x 10⁵ and 4.4 x 10⁵. The results reveal that when the wind angle is not normal to the rotating plane of the wind turbine, there is a significant power loss. A power loss of around 25% is experienced when the wind is at an angle of 22.5 degrees from the normal of the spinning plane. Furthermore, when the angle is negative 45 degrees from normal, the wind turbine does not attain the required speed to create power, resulting in a 100% power loss. Using an intelligent system containing a control system, the problem of power loss was avoided. Consequently, the direction of the wind will be consistently normal to the rotational plane, and the maximum power output of approximately 3 watts is maintained throughout the working hours of the turbine.
