Design and Simulation of A Small Wind Turbine Blade with Qblade and Validation with MATLAB

摘要

This paper presents designing blades of small horizontal axis wind turbine for low wind speed area. In this case, Blade element momentum theory has been employed to find optimum value of chord length and twist angle. The blade performance has been illustrated in terms of coefficient of power, coefficient of thrust, coefficient of torque and so on. All this design procedure and analysis have been undergone with the help of Qblade, a dedicated as well as validated software for designing and simulating of wind turbine. Moreover, it has been validated with the help of MATLAB by implementing blade element momentum method. The simulation result from Qblade shows that rotor can extract maximum 48% wind energy having start-up speed of 2 m/s.
