Abstract

The population growth is increasing every year in line with the energy consumption needed by each country. Therefore, people increase the development of alternative energy that is environmentally friendly and renewable sources. Micro hydropower plants are small-scale power plants that utilize the potential energy of water. A water crossflow turbine is one of the components that serve to convert the potential energy that water has into kinetic energy to generate electricity. The purpose of this study was to determine the influence of v sectional angle variations on power and efficiency in horizontal shaft crossflow turbines. This study used an experimental method using variations in angle of runner by 120°, 130°, 140° and 150° with a total of six runners and variations in water flow capacity of 9.5715 L/s, 11.0231 L/s, 14.3205 L/s, and 18.1116 L/s. And loading variations as well. The results of this study on variations of angles at 120°, 130°, 140° and 150° obtained optimum turbine power generated from at a 120° angle at a capacity of 18.116 L/s of 2.498 Watts with a load of 4000 grams and has a load resistance of up to 10000 grams. While the maximum turbine efficiency is generated at a 120° angle at a capacity of 9.5715 L/s of 90.94% with a load of 4000 grams and has a load resistance of up to 6000 grams.
