Performa Model Tes Hidrolis untuk PLTMH Head Rendah dengan Menggunakan Tekanan Aliran dan Kecepatan Pusaran Air (Vortex)

Abstract

Electricity is the main source of energy in human life. The development of human life is greatly influenced by the presence of electrical energy. Therefore it is necessary to conduct research related to the generation of electrical energy on a small scale (micro). One alternative electricity generation by changing the motion energy is done by utilizing the flow of water. Water flow with low discharge and head is easily found in several places, especially small rivers or irrigation channels. Utilization of low flow head and discharge is a great potential to be able to produce small-scale (micro) electrical energy. In this research, modeling of low flow and low head discharge will be carried out to find out how much potential the electrical energy can generate. There are 3 experiments namely water power, whirlpool, high fall. Experiment 1 with a head of 50 meters found 1,414 watts of water power with a discharge rate of 17.3 liters/minute on a 1 "diameter pipe. In experiment 2 the performance of the tool could not produce a vortex flow according to the plan, because the cross-sectional area was not comparable to the basin's outer hole and only produced vertices at a depth of 10 cm flow and produced a vortex radius of 1 cm. In Experiment 3 the performance of the tool can run well the stability of the discharge generated from the sedative bath shows that the measured flow velocity is in accordance with the theoretical flow rate conditions. Ie the speed of flow increases due to high fall.
