Pengukuran dan Perhitungan Kinerja Turbin Angin Sumbu Horisontal Tiga Sudu Skala Rendah

Abstract

Electrical energy is a part that can not be separated from human life. Almost the whole aspect in human life needs electrical energy, the general source to rise up electricity is fossile source energy which is limited and non renewable enhancement needed, limited fossile source also negative effect that produce makes the grown up technology of renewable energy. Wind is one of reneweble energy source and it green power. Wind energy can be used with wind turbine. The chosen of wind turbine in this final examination is three horizontal axis wind turbine low scale. It has 120 cm blade diameter. Flow simulation using computer sofware to predict flow condition at airfoil section blade and estimating the optimum angle of attack to produce larger lift or drag ratio. Calculation with computer sofware also use to predict influence power output like pitch agle, yaw angle, tilt angle, precone angle and the length of blade in certain condition. Flow simulation also use to predict starting torque value in certain condition and perceive pitch angle influence against starting torque rotor value.
