Prototype Performance Of Microhydro Power Plant Is Viewed From The Shape Of The Waterwheel Blades To The Generated Electrical Energy

Abstract

In order to overcome the electrical energy crisis, has done a lot of research on the utilization of new renewable energy, one of which is water energy. Currently the utilization of water as a power plant becomes one of the researches that continue to be developed because of its abundant potential. In this study, a prototype simulation of Powerhouses of Microhydro Power. The prototype of PLTMH wants to know the influence of the shape of the spindle blades in generating electrical energy. The research methods are literature study and laboratory-scale design study. The procedure is carried out with fixed variable that is, the direction of the pusher water, the nozzle opening whereas the variable is not fixed that is the shape of the spindle blade (flat plate blade or bowl blade). Based on the results of research that has been done there is the influence of the form of the wind turbine blades in producing electrical energy is a flat plate flat blade is better to produce electrical energy than bowl blade. On a flat plate blade flat the water flow rate of 1 - 25.3 Liter/min has not produced electrical energy, the flow rate of 25.4 - 31.9 Liter/min can produce electrical energy with the largest electrical energy generated at 140 watts. While the bowl blades plate flow rate of 1 - 25.1 L / m can not produce electricity, the flow rate of 25.2 - 31.8 Liter/min can produce electricity with the largest electrical energy generated by 111 watts.
