An Investigation into the Impact of Elbow Angle, Flow Rate, and Flywheel Diameter on the Performance of a Micro Hydroelectric Power Plant (PLTMH) Prototype

The Micro Hydroelectric Power Plant Simulator (MHP) serves as a teaching tool to understand the principles and factors influencing electrical power output. While previous studies have examined the impact of turbine types, elbow angles, and flow rates, limited research has focused on the effect of flywheel diameter. The flywheel diameter influences the torque generated for generator rotation. This study, conducted on the MHP simulator at the Energy Laboratory of Jakarta State Polytechnic, explores the effects of variations in elbow angle, flow rate, and flywheel diameter on electrical power output. Experimental results reveal that these parameters significantly impact power generation. Notably, in case 1, with a 45° elbow angle, a flow rate of 7 L/s, and a 30 cm flywheel diameter, the system produces the highest output of 63 W. These findings underscore the importance of flywheel diameter in optimizing micro-hydropower system efficiency, offering insights for future plant design, especially in water-scarce regions.

Abstract

The Micro Hydroelectric Power Plant Simulator (MHP) serves as a teaching tool to understand the principles and factors influencing electrical power output. While previous studies have examined the impact of turbine types, elbow angles, and flow rates, limited research has focused on the effect of flywheel diameter. The flywheel diameter influences the torque generated for generator rotation. This study, conducted on the MHP simulator at the Energy Laboratory of Jakarta State Polytechnic, explores the effects of variations in elbow angle, flow rate, and flywheel diameter on electrical power output. Experimental results reveal that these parameters significantly impact power generation. Notably, in case 1, with a 45° elbow angle, a flow rate of 7 L/s, and a 30 cm flywheel diameter, the system produces the highest output of 63 W. These findings underscore the importance of flywheel diameter in optimizing micro-hydropower system efficiency, offering insights for future plant design, especially in water-scarce regions.
