Abstract:
Utilizing wind energy with vertical-axis wind turbines is an appealing solution for reducing dependence on fossil fuels. These turbines offer several advantages, including the ability to operate in various wind directions and their suitability for installation in locations with limited space. One of the key benefits of this technology is its adaptability to changes in wind direction and speed, along with ease of operation and maintenance. However, challenges remain, such as improving energy conversion efficiency and addressing relatively high initial investment costs. The research methods included a literature review, design planning, and field testing to assess the performance of vertical-axis wind turbines. Tests were conducted to measure wind speed, as well as the voltage and current produced by the generator, in order to determine its power output. The results indicate that vertical-axis wind turbines possess significant potential for efficiently generating electricity across a range of wind conditions. At a wind speed of 4.2 m/s, the turbine rotates at 62 rpm, producing a no-load voltage of 12.9 volts. When loaded for battery charging, the generator produces 3.56 watts of power, with a voltage of 7.9 volts and a current of 0.45 amperes.
