Rancang Bangun Pembangkit Listrik Tenaga Angin Menggunakan Turbin Archimedes dengan Variasi Sudut Masukan Angin

Abstract

Wind is one of the renewable energy sources abundantly available in nature and will not be depleted. This energy can be utilized for various purposes, including as a driving force for power generation. This study aims to examine the performance of a modified Archimedes wind turbine blade, designed to operate effectively in regions with moderate wind speeds ranging from 5.5 m/s to 8.5 m/s, based on the Beaufort scale. The turbine was tested using wind input angles of 0°, 15°, and 30°. The results showed that at a wind speed of 8.5 m/s and a 30° input angle, the generator achieved a rotational speed of 819.4 RPM and an output voltage of 25.8 V under no-load conditions. When loaded with a 9-watt DC lamp, the generator produced a current of 4.1 A, a rotational speed of 370.8 RPM, and an output voltage of 11.7 V. Under a 12-watt DC lamp load, the current output was 0.4 A, with a rotational speed of 354.1 RPM and an output voltage of 11.2 V.
