A Micro Hydro Pelton Turbine Prototype (Review of the effect of water debitand nozzle angle to rotation and pelton turbine power)

Abstract

This research began when the writer conducted a field study to Curup Tenang Bedegung Waterfall, Tanjung Agung District, Muara Enim, South Sumatra. The CurupTenang Bedegung waterfall has the potential to build a micro-hydro Pelton turbine power plant. This study aims to see the flow rate andwater discharge. From this preliminary study, the researcher decided to carry out the design of a micro-hydro Pelton turbine prototype on a mini scale but has optimal rotation and power. In this study, the analyses of the effect of water dischargewere 20, 25, 30, 35, and 40 1/s and the nozzle angle was 50 °, 55 °, 60 ° and 65 ° toward rotation and Pelton turbine power. From the results obtained the higher the water discharge, the turbine rotation is increasing, the highest turbine rotation (691.3 rpm) achieved was at a water discharge of 40 l/s with nozzle angle of 50 °, the higher the water discharge will increase turbine power, the highest turbine power (15.89 watts) was obtained at a water discharge of 40 l/s with a 50 ° of nozzle angle.
