Abstract

Indonesia merupakan suatu negara yang memiliki potensi angin yang cukup rendah yaitu hanya sekitar 2-4 m/s pada wilayah daratan. Berdasarkan potensi kecepatan angin yang rendah, turbin angin jenis savonius merupakan salah satu alternatif yang dapat digunakan untuk mengubah energi angin menjadi energi listrik. Kekurangan dari turbin angin jenis savonius adalah memiliki Cp yang relatif rendah jika dibandingkan turbin angin jenis lain. Penelitian dalam meningkatkan Cp turbin angin savonius telah banyak dilakukan diantaranya melakukan adjust pada geometri bilah turbin dan diameter overlap serta konfigurasi array untuk instalasi turbin berskala besar. Sementara itu, studi yang dilakukan ini bertujuan untuk mengetahui pengaruh dari jumlah bilah, jarak antar turbin, sudut datangnya angin dan variasi kecepatan angin terhadap kinerja savonius wind-turbine farm. Kinerja dari masing – masing konfigurasi dipengaruhi oleh interaksi aliran yang terjadi di daerah gap antar turbin. Interaksi aliran tersebut menyebabkan superposisi aliran antara kecepatan induksi yang disebabkan karena bilah yang berputar dan kecepatan aliran inlet. Pada kecepatan yang tinggi dan jarak antar turbin yang dekat, efek interaksi aliran di daerah gap turbin semakin besar. Kofigurasi jarak antar turbin 2D dengan sudut arah aliran 0ᵒ menunjukkan efek konstruktif terbesar yang ditandai dengan nilai nilai efektifitas farm mencapai 1.61 pada kecepatan inlet 8 m/s sedangkan efektifitas farm paling kecil terdapat pada konfigurasi jarak antar turbin 4D dengan kecepatan inlet 1 m/s sebesar 1.01. Berdasarkan dari penelitian yang telah dilakukan rata-rata Cp maksimal yang dapat dihasilkan turbin terdapat pada konfigurasi varasi jarak antar turbin 2D, dengan jumlah 2 bilah dan sudut arah aliran 0ᵒ pada kecepatan aliran inlet 8 m/s sebesar 0.28. Sedangkan nilai rata-rata Cp terendah terdapat pada konfigurasi variasi jarak 4D, dengan jumlah 3 bilah dan sudut arah aliran 45ᵒ pada kecepatan aliran 1 m/s sebesar 0.16.

Indonesia is a country that has quite low wind potential, namely only around 2-4 m/s on land. Based on the potential for low wind speeds, the Savonius-type wind turbine is an alternative that can be used to convert wind energy into electrical energy. The disadvantage of the Savonius-type wind turbine is that it has a relatively low Cp compared to other types of wind turbines. Much research has been carried out on increasing the Cp of Savonius wind turbines, including adjusting the turbine blade geometry and overlap diameter as well as array configurations for large-scale turbine installations. Meanwhile, this study aims to determine the effect of the number of blades, distance between turbines, angle of flow direction, and variations in wind speed on the performance of the Savonius wind turbine farm. The performance of each configuration is influenced by the flow interactions that occur in the gap area between the turbines. The flow interaction causes a flow superposition between the induced velocity caused by the rotating blades and the inlet flow velocity. At high speeds and close distances between turbines, the effect of flow interaction in the turbine gap area becomes greater. The configuration of the distance between 2D turbines with a flow direction angle of 0ᵒ shows the greatest constructive effect, as indicated by the farm effectiveness value reaching 1.61 at an inlet speed of 8 m/s, while the smallest farm effectiveness is found in the configuration of the distance between 4D turbines with an inlet speed of 1 m/s of 1.01. Based on the research that has been conducted, the average maximum Cp that can be produced by the turbine is in the configuration of the variation of the distance between the 2D turbines, with a total of 2 blades and a flow direction angle of 0ᵒ at an inlet flow speed of 8 m/s of 0.28. Meanwhile, the lowest average Cp value is found in the 4D distance variation configuration, with 3 blades and a flow direction angle of 45° at a flow speed of 1 m/s of 0.16.
