Abstract

Indonesia's electricity needs are increasing from year to year, but the availability of fossil fuels such as oil and coal is decreasing, so that new and renewable energy sources are needed as a solution to overcome the problem. One of the renewable energy sources that can be utilized and has great potential is wind energy. The purpose of this study was to determine the optimal taper blade with airfoil for a micro-scale horizontal axis wind turbine. In this study, horizontal axis wind turbine blades with GOE 796 airfoil were tested using a cooging-less PMSG generator in order to achieve high efficiency at minimum wind speeds. The design of the GOE 796 Airfoil Taper blade has a radius of 1 m, a chord width of 34-74 mm, with a twist angle of 5.66-11.66°. The results of the analysis of the performance of the Taper GOE 796 Airfoil blade with a maximum wind speed of 10 m/s has optimal performance at TSR 6.5 with a Coefficient Power (Cp) of 35%, producing a maximum power of 670 W at a rotation speed of 620 rpm and a torque of 10.3 Nm.

Abstract

The wind turbine that has the best performance for urban areas with easy maintenance is the Darrieus-H Vertical Axis Wind Turbine (TASV). The purpose of this study was to determine the characteristics of the NACA 0012 airfoil, to determine the effect of blade height on TASV performance, and to obtain the optimum blade design. The method used in this research is the simulation and analysis method. Wind turbine simulations and analysis were carried out using Microsoft Excel software to process data, Rotor DMS Simulation on Qblade to determine airfoil characteristics and analyze wind turbine performance, and Ansys FLUENT to determine fluid flow that occurs in the blades. In this study, with regional conditions in West Java having an average wind speed of 6.83 m/s and a maximum wind speed of 10 m/s, simulations and analysis with several variations in height obtained the results that the Darrieus Vertical Axis Wind Turbine (TASV) blade H has the same maximum Coefficient Power (Cp), which is 73% at a TSR of 4.5. In the study, also with a 300 W generator, the optimum blade height was obtained, which has a design of 0.7–1.1 meters with a power generated of 99.8–492 W with a torque of 1.72–5.80 Nm at a rotor rotational speed of 55.05–85 rad/s.
