Optimization of a low head microhydro system for electricity generation

Abstract
One of the most used renewable energy nowadays is hydro energy. However, large hydro systems are expensive to construct and maintain. The use of microhydro systems has great potential in generating electricity for farm use. A propeller type turbine for low head microhydro system was analyzed and two factors were incorporated in the study. These factors are the configuration of the draft tube and the speed ratio of the transmission system to generate electricity. The maximum power generated by the microhydro system is around 86.9 W. This power occurred in the combination of a modified draft tube and speed ratio of 3:8. However, the most efficient microhydro system is the combination of the original draft tube with a speed ratio of 3:8. The efficiency reached up to 31.7% producing the optimum power of 72.8 W. The investment for the microhydro system costs around US $ 2,028.44 or PhP 91,280.00. About US $ 1,017.33 or PhP 45,780.00 of the total cost is contributed to labor cost and $ 1,011.11 or PhP 45,500.00 is accounted for material costs. The cost of the microhydro system can be further reduced if fabrication of components is through mass production.
