DESIGN, FABRICATING AND TESTING A WIND TURBINE APPLIED IN AGRICULTURE

The application of renewable energy in agriculture for sustainable development and greenhouse gas emission reduction is increasingly necessary. Shrimp farming areas possess significant wind potential, providing favorable conditions for designing and developing wind turbines to harness this natural energy source. This study aims to design a wind turbine to drive aerator paddles for shrimp ponds and water pumps for irrigation, thereby reducing electricity consumption and operational costs. The research includes surveying, measuring, and evaluating wind potential in typical shrimp farming regions. Based on low wind speeds ranging from 2 to 5 m/s and torque requirements, a multi-blade turbine with a 2-meter diameter and power output of 5 – 202 W was selected and designed. The fabrication, installation, and testing results demonstrate stable turbine operation with an average wind speed of 3.2 – 5.8 m/s, speed of the aerator paddles of 65 – 230 rpm, power output 51 – 181 W, suitable for agricultural applications. With an average wind speed of 2.1 m/s, the water pump driven by this turbine has a flow rate of 13.6 m³/day, corresponding to a pump head of 4 meters. The study confirms the feasibility and effectiveness of wind turbines in shrimp farming, contributing to the promotion of green agriculture models, emission reduction, and decreased reliance on traditional grid electricity.
