Design of Crossflow Turbine for Picohydro Power Plant in Singosari, Malang

Abstract

In the area around PPYD Al Ikhlas Singosari, Malang, there is a river with a fast enough flow that can be used as a hydroelectric power plant as estimated. After investigation, it was found that the potential electrical power that could be generated was 1,118.56 Watts so it was classified as a pico hydro power plant. Therefore, in this research, one of the main parts of the pico hydro power plant, namely the turbine, was designed. The type of turbine designed is a crossflow turbine with an outer diameter of 75 cm and an inner diameter of 3 cm, the width of the runner blades is 40 cm, the distance between the blades is 36 cm, the radius of curvature of the blades 33 cm, the number of 10 blades can produce 843.74 watts of power with a turbine efficiency of 75.43%. So, it can be concluded that the crossflow turbine has good efficiency.
