A Study of Vertical Wind Turbine for Application in Low Wind Speed Condition in UiTM Terengganu, Malaysia

Abstract

This paper presented an investigation of an energy generation project by using a wind turbine in UiTM Terengganu, Malaysia. The significance of the project is to evaluate the proposed wind energy setup with the tropical environmental condition, especially in Malaysia. The wind turbine is built close to the seashore and facing the South China Sea. A relationship between wind speed with and the voltage level at the energy generator output terminal is analysed theoretically. Published wind speed data has been used in determining a suitable wind turbine system. Actual wind speed data is recorded starting from June 2017 until December 2017, and the data is compared with the published results. It has been found that the recorded data is in line with the published results. Moreover, it has been found that the mean wind speed collected at the proposed site is low, which is 2 m/s to 3.7 m/s. Furthermore, the wind turbine is actively producing energy for approximately 4 hours per day. A 300 W vertical axis wind turbine has been developed and tested, and it has been found that the efficiency of the energy generating system is less than 10%, which contributes for a significant amount per month.
