Abstract
Pico Hydro Power Plant (PHPP)is a hydroelectric power plant with a scale below 5 kW. This technology is suitable to be applied to areas that have many rivers with sloping slopes. The PHPP applied in this research utilized the river flow then flowing the water through a water way with a slope angle around 10 degrees. Due to this sloping angle, it is necessary to modify the turbine intake to produce a more rapid water flow so that the turbine can rotate faster. The modification is made by designing and making a spiral vortex hydro turbine, where the intake is designed to resemble a snail house or a whistle to produce a spiral whirlpool to drive a turbine. Then, the turbine will be coupled with a generator to produce electricity. The results show that the spiral vortex hydro turbine can produce faster turbine rotation, compared with a conventional water intake. The faster the turbine rotation, the higher the generator output voltage. In addition, the device is easy to move and maintain due to its portable design.
