In Malaysia, the conventional industry practice typically involves the use of wind turbine blades designed for maximum efficiency in high wind speed conditions, which are rarely encountered in the country. This project seeks to address this mismatch and develop innovative solutions for harnessing wind energy in low-wind speed regions.
This project addresses the critical issues of reducing Malaysia's heavy reliance on coal-based electricity generation, achieving renewable energy targets, and harnessing wind energy efficiently in low-wind speed regions, ultimately contributing to a sustainable and environmentally friendly energy landscape. Ministry of Natural Resources, Environment and Climate Change (NRECC) set a target to reach 31%of RE share in the national installed capacity mix by 2025.The prevailing practice in the industry typically involves the utilization of conventional wind turbine blades that are specifically engineered to achieve maximum efficiency when exposed to high wind speeds, a condition not frequently achievable in Malaysia.
The solution is to modify the leading edge of the blade turbine and incorporate a Tubercle Leading Edge (TLE). The modified Horizontal Axis Wind Turbine blade showcases an innovative design and wind power system that optimizes aerodynamic efficiency. The uniqueness of this invention lies in its advanced wind turbine blade design, which enhances the system's start-up speed and enables higher energy storage at low wind speeds. It is suitable for areas with relatively mild and consistent winds. The idea of these tubercles was observed in humpback whales. The tubercles on the leading edge of the whale flippers function as control mechanisms, preserving lift and averting stall at steep angles of attack.The ULTRA-LOW SPEED WIND ENERGY SYSTEMS will generate more power and be able to start at lower wind speeds, which are the ones experienced in the country. The presence of tubercles allows the turbine to start generating power and produce higher energy output at low wind speeds. It is suitable for areas with relatively mild and consistent winds.
