Performance Analysis of Cone Basin-Based Gravitational Water Vortex Power Plant (GWVPP) by Variations in the Number of Blades

The electricity supply is not evenly distributed for all regions in Indonesia. This due to the lack of transportation access reach these areas because difficult terrain conditions. One abundant energy sources available nature water, which can be used micro-level power generation. Micro hydro generator usually uses a waterfall with high head. However, water flow has head tall. Therefore, this study proposes promising prototype cone basin-based Gravitational Water Vortex Power Plant (GWVPP). purpose determine performance GWVPP by variation number blades. vortex turbine designed rate 169.63 liters/minute and basin square-shaped blades variations blades, namely 2, 4, 6, same blade area 0.01 m2 . It was found that an increase enhances mechanical characteristics of, e.g. torque rotational speed, as well electrical characteristics, voltage, current, electric power. maximum result achieved when six rated 5 mW rotation speed 119.351 rpm.
