Abstract

Renewable energy is still an ever-expanding industry in power generation, especially in the tropical country Malaysia where solar power is prominent due to its geographical location. Wind power has been a challenge for power generation especially in a low wind speed area. Therefore, this study will try to generate power to at least power up a small device using wind power with a HAWT. The small scale HAWT would be tested with three blades and five blades at different blade lengths; 27cm, 32cm, 37cm, 42cm and 47cm, as well as different blade angle at angle 4.2˚,8.4˚,12.6˚ and 21˚. The wind speed of Kota Kinabalu area was also collected using the weather API with the month April recording the highest at 2.5m/s and lowest in February at 1.8m/s in the year 2022 across seven months December 2021-May 2022. The study recorded data of current, voltage, turbine rotation, and lastly wind speed in the controlled area for testing to determine the power output, coefficient of power and also tip to speed ratio from the blade length. The three blades HAWT recorded the highest power output at 1.42W from 42cm blade length (12.6˚ blade angle), at 0.3 efficiency where the five blades HAWT recorded its highest power output at only 1.07W using 27cm blade length (12.6˚ blade angle), at 0.5 efficiency.
