Development of Vertical Axis Wind Turbine (VAWT) During Windy Season for the Rural Area in Langkawi

Abstract

Wind energy is one of the clean energy sources. This project is carried out to take advantage of the windy season inland and along the coast of Langkawi. Wind energy is converted into electricity by driving a brushless generator motor to produce a Direct Current (DC) voltage of 12V. The output voltage from the DC motor will be stored in the battery before being fed to the inverter. These inverters are used to convert DC energy into Alternating Current (AC) output. The AC output can be increased by using a transformer up to 220 VAC. The voltage output from the inverter will be fed to the user to turn on electrical appliances at home. Electricity supply is very important nowadays because of the rapid development of technology. Some residents in rural areas do not get electricity from Tenaga National Berhad (TNB). This is because their place of residence is too far or isolated. To ensure they have a constant supply of electricity, a system called the Vertical Axis Wind Turbine (VAWT) has been designed. With this system, power supply troubleshooting can be improved to turn on electrical equipment such as lights, fans, ice boxes, and more. This system is developed by using wind energy which is one of the other methods to supply electricity. The results from the experiment show that as the wind speed increases, the output power from the DC motor will increase. The proposal uses specialized software and designs wind turbines that will be able to generate voltage and current.
