Rancang Bangun Dan Analisa Pengaruh Kemiringan Dan Jumlah Bilah Pada (Pltmh) Turbin Ulir

This study aims to determine the effect of variations in the inclination angle of screw turbine blades (20°, 30°, and 40°) and the number of blades (1 and 2blades) on the performance MicrHydroPowerPlant(MHPP). Theobservedparameterinclude turbine rotation (rpm), turbine power (W), electrical power (Watt), andefficiency (%) under three load conditions: no load, 9 W load, and 12 W load.The experiment was conducted using a constant water flow and low head. The results showed that under no-load conditions, the best performance was obtained with a 2-blade configuration at a 40° inclination angle, producing 289 rpm, 30.25 W of power, and 90.7% efficiency. At a 9 W load, the best configuration was 1 blade with a 40° inclination, producing 283 rpm and 29.6 W of power. Under a 12 W load, the highest performance was also achieved with a 1-blade configuration at 40°, producing 278 rpm and 29.10 W of power. In general, the results indicate that increasing the blade inclination angle up to 40° provides the most optimal performance in generating power and efficiency under all conditions. This configuration maximizes the utilization of water flow energy and is suitable for MHPP systems operating under low head conditions.
