Abstract

Water as a renewable natural resource holds great potential for utilization in micro-scale power generation in rural areas. The Pelton turbine is a common choice for conditions with a high head but low flow rate, although its performance heavily depends on design parameters and operational conditions. This study aims to examine the impact of variations in head (1,200 mm, 1,500 mm, 1,800 mm), nozzle distance (150 mm, 160 mm, 170 mm), runner diameter (170 mm, 190 mm, 210 mm), and bucket angle (150°, 160°, 170°) on the performance of a micro hydro Pelton turbine. The method used is an experimental approach utilizing a laboratory-scale Pelton turbine prototype. The collected data includes flow rate, rotational speed (RPM), voltage, and electric current, which were subsequently calculated to determine hydraulic power, turbine power, and efficiency. The results indicate that increasing the head from 1,200 mm to 1,800 mm can enhance efficiency from 84.2% to 92.9% and turbine power from 1.706 Watts to 4.825 Watts at the best parameter combination. The closest nozzle distance (150 mm) yielded the highest efficiency and power. A runner diameter of 170 mm was consistently better compared to the 190 mm and 210 mm diameters. A bucket angle of 170° produced the most superior performance across all testing conditions. The most optimal parameter combination was achieved at a head of 1,800 mm, a nozzle distance of 150 mm, a runner diameter of 170 mm, and a bucket angle of 170°, reaching an efficiency of 92.9% and a turbine power of 4.825 Watts. The findings of this study can serve as an empirical reference in designing more efficient micro-hydro Pelton turbines.
