Karakteristik Model Turbin Angin Untwisted Blade Dengan Menggunakan Tipe Airfoil Nrel S833 Pada Kecepatan Angin Rendah
Abstract: Increasing energy
needs from time to time lead to scarcity of energy in many countries. To
overcome this energy shortages several countries race to generate energy from
new sources of renewable energy. Wind is one of the renewable energy source that
is environmentally friendly. In the area of low wind speed small scale wind
turbines can be used to generate electrical energy. This research was conducted
to find out the characteristics of the wind turbine model working on low wind
speed. Model of the wind turbine used is a three bladed horizontal axis wind
turbine with a rotor diameter of 70 cm. The Wind turbine has untwisted blades,
made of fiberglass and has a cross-section of airfoil NREL S833. The wind used
in this study came from a fan that serves as the source of the wind with wind
speed variation of 2,43 m/s, 2,98 m/s and 3,23 m/s. The result of the study
showed that the wind turbine model works the best at pitch angle of 100. On the
100pitch angle, the characteristics of the power to rotation speed and the
power coefficient (cp) to tip speed ratio (λ) for every wind speed variation
were derived. The maximum power derived at wind speed of 2.43 m/s, 2.98 m/s and
3.23 m/s each is 0.605 W at 406 rpm by cp=0.18 at λ= 6.1; 1.311 W at 513 rpm by
cp=0.21 at λ=6.3; and 1,673 W at 561 rpm by cp=0.21, λ = 6.3.
