Experimental study on pitch angle effects on the performance of Sg-6043 horizontal wind turbine

Abstract

Worldwide energy usage continues to increase along with the depletion of fossil fuel reserves. This condition encourages society to develop renewable energy. Wind is one of the form of renewable energy which has low utilization. Furthermore, the available wind turbine has low efficiency especially in low wind speed condition. One way to improve a wind turbine’s performance in a low wind speed is the use of pitch angles. This study aims to determine the effect of pitch angle on SG-6043 wind turbine, the pitch angle variations used are 0°, 2°, 4°, 6°, 8°, 10°, 12° and 14°. The data were collected using an experimental wind tunnel. The test results show that the pitch angle of 10° produces the most optimal power when compared to other angles, which is 6.82 watts, whereas the angles 0°, 2°, 4°, 6°, 8°, 12° and 14° produces power of 0; 0; 0; 0; 6.50; 6.55; 6.30 watts respectively.
