Perancangan Prototipe Turbin Angin Sumbu Horizontal Tiga Sudu Studi Kasus Institut Teknologi Kalimantan

As a new institute where located in the middle of forest, Kalimantan Institute of Technology (ITK) need a new energy resource to fulfill the demand of electricity power as the increasing of students. Based on wind speed data collection from Meteorology, Climatology and Geophysics Agency (BMKG) in 2017, the average wind speed in Balikpapan ranges from 5 km/h 18 km/h. Based on this data, a wind turbine becomes one of potential renewable energy that can be developed. In this study, horizontal axis wind turbine with three blades is used. The variation of angle of attack and wind speed will be observed to get the best combination of electricity power production. The variation of angel of attack are 5, 10, and 25 , while the wind speed varies from 3.8 m / s, 4.3 m/s, 5.8 m/s. The experiments demonstrate that the angle of attack 25 and wind speed 5.8 m/s produce the largest electric power with the number of 118.7 mW.
