COMPARATIVE ANALYSIS OF SMALL-SCALE WIND TURBINE DESIGN FOR THE LOW RATE WIND SPEED

This paper reports developments and tests of simulation and a prototype for wind turbine with blade diameter of 2 m, with three blades of airfoil NREL S83n. Crucial problem in implementation of small scale wind turbine for low wind speed regimes ( i.e. 3.8-7.5 ms -1 , like in most areas in Indonesia), is to determine the position of pitch angle of turbine blade. The right position of blades’ pitch angle may produce maximum mechanical power, wich means also maximum electrical power. The proof of concept experiments were done by considering pre-determined dimension, type and diameter of blade, as well a range of angular velocity and power produced. The prototype of turbine was exposed to variation of wind speed flow, and stepwise variation of blades’s pitch angle was set through PC, with angular step of 5 0 for range of angle 0-90 degrees. Optimal pitch angle 0f 15± 5 degree was obtain, with a maximum value of Cp=0.54 for a prototype and 0,59 for simulation.
