Abstract

Utilization of wind energy potential in Indonesia is still small due to the range of wind characteristics in Indonesia frequently changing direction change and its average speed is also categorized low. For that we need to develop high-efficiency wind turbines at low wind speeds. In this research, a Savonius turbine model was developed as the main blade with 2 obstacle blades, the model was tested in a subsonic wind tunnel at wind speeds of 3-6 m / s with variations in the gap of the main and obstacle blades are 2, 4 and 6 cm. The results explained that at a gap of 6 cm, the presence of an obstacle blade can improve the performance of Savonius wind turbine models by 77.74% at a tip speed ratio of 0.88. In addition, the presence of obstacles can increase the ability of wind turbines to do self-starting. Keywords— distance gap, double layer blades quarter, obstacle blades, performance, self-starting
