Design and Implementation of a Portable Pico Hydro Power System for Low-Head Applications Using a Cross-Flow Turbine

Abstract

Portable hydroelectric power plants are generally created as hobbyist tools and are not optimized for specific performance requirements. This research focuses on designing and developing a portable Pico Hydro Power Plant (PHPP) equipped with a cross-flow turbine, capable of operating at a very low head of less than 3 meters. The system is designed to deliver 20W of electrical power, sufficient for basic needs such as lighting or charging electronic devices like laptops and smartphones, particularly in remote locations. Previous efforts resulted in a prototype PHPP with a cross-flow turbine, but several challenges arose during manufacturing, installation, and testing due to its construction using 3D printing techniques. This study addresses these challenges by redesigning key components, including the turbine housing, nozzle, outlet, bearing housing placement, and turbine runner. The updated PHPP simplifies the manufacturing process, installation, and operation. Additionally, fluid flow simulations were conducted to evaluate pressure distribution, velocity, and flow patterns within the turbine. Experimental testing at a head of 2.3 meters revealed an electrical output of 20.5W and a turbine efficiency of 39.6%. These findings indicate that there is potential for further improvement, particularly in the design of the nozzle and runner, to enhance overall efficiency and performance.
