    Renewable energy is a reason why this study has been chosen. In this paper focused on an analysis of the characteristics of the wind when the wind turbine blade is encountered using a commercial fluid dynamics solver such as Fluent by selecting the impact angle of 5, -5, 10, 15, 20, -10, -15 and -20 degrees. Aerodynamic characteristics such as lift coefficient, drag coefficient, lift to drag ratio has been evaluated in this study. Fluent simulation results will be compared with the result of the milling airfoil tested in wind tunnel. Our goal is to a construction of wind turbine in low wind speed country like Thailand.

    At the present time, the demand for energy in Thailand is increasing rapidly. Therefore, improving production efficiency is important in solving energy problems. According to the Alternative Energy and Alternative Energy Development Plan 2015-2036 in Thailand, the objectivity for wind power generation has increased dramatically. For this reason, the research team had the idea to create a wind tunnel with adjustable wind speed to mimic local wind speed in Thailand to be used in designing and analyzing wind turbine blade designs to suit various wind speeds. This can increase the efficiency of the production of energy even more. Wind speed adjustment or the pressure, lift and rotation speed measured can be done by a computer. By applying the PID control theory, it can precisely control the wind speed.

    In this paper, the AC-AC converters using 2-step current commutation, 4-step current commutation, 2-step voltage commutation, 4-steps voltage commutation, and 3-steps voltage-current commutation will be used for a power converter system are proposed. The system is simulated and calculated with MATLAB/Simulink. This paper discusses each method, its difference, and its power loss.
