Abstract
The present work shows the design of a Pelton turbine for micro hydropower. This present work aims to design a Pelton turbine for micro hydropower that can produce a maximum power output of 32kw using water resources available in Ethiopia's rural areas with a maximum head of 15 m. This present work also includes designing each component of the Pelton turbine and selecting material for each component. In this work, design calculations and detailed drawings are also shown. The design results are tabulated based on variable head and flow rate. Material selection and the reason behind the selection are shown based on criteria predetermined. Finally, the conclusion is derived from the result analysis. If the distribution of the annual flow rate of water varies, the designed turbine will work up to a minimum flow rate of 0.15 m3/s delivering a minimum of 19.04 kW output power. This turbine will also work under the variable head of 10 m to 15 m range, delivering appropriate power. This turbine will give 31.74 kW power under a full head of 15 m and 19.04 kW power under a minimum head of 10 m. The designed turbine can be used effectively for improving power shortage around rural areas of Ethiopia. It will give 31.74 kW output power if it works under full head and flow rate. It will serve 317 households living in a rural area, assuming each household consumes 100 W.
