Rancang Bangun Pembangkit Listrik Aliran Arus Sungai

Abstract

The increase in high economic growth as well as the needs and demands of the community in the use of electrical energy are increasingly high. Utilization of river flow has not been utilized optimally to assist in meeting the needs of electrical energy. In West Kalimantan, especially in Sungai Jelayan Village, Kendawangan District, Ketapang Regency. The river flow in the base of Pinang hamlet has a river flow that always flows continuously, because the condition of the river does not have a height difference so that the design of the power plant designed with the floating crossflow type will maximize the potential that exists in the river flow in Sungai Jelayan village. This research was conducted to test the design of the floating PLTPH in Sungai Jelayan Village to find out how much electrical power can be generated in the river and to determine the efficiency of the PLTPH. The research was conducted for one week the greatest electric power generated when the discharge from river water was 416 liters in a second with a generator voltage of 16.81V and a generator current of 1.4 A or equivalent to 23.54 W then the lowest electric power was generated when the discharge from water river of 350 liters in a second with a generator voltage of 16.34 V and a generator current of 0.78 A or equivalent to 12.87 W. The maximum tool efficiency occurs when the generator power is 21.23 watts and the water power is 55.26 with an efficiency of 38, 42%.
