Abstract

Pico hydro Power Plant (PLTPH) is a small-scale hydroelectric power plant that utilizes the conduit of water flow by converting potential energy into mechanical energy. The vortex turbine utilizes a whirlpool formed by the vortex turbine housing to push the blades to rotate. In this PLTPH prototype research, the vortex turbine was designed with a 2050 mm penstock head, a 6 inch input pipe with the use of a nozzle as an intake with a narrowing in size from 6 inches to 3 inches, a water discharging of 37.96 L/s, a vortex turbine housing with a diameter of 590 mm, a height of 470 mm, and an outtake of 4 inches. The runner design is equipped with 8 blades with a width of 220mm, a height of 225mm with a shaft diameter of 1 inch, and a shaft length of 1060mm. The design and manufacture of this prototype requires supporting components such as: a). hanging scales; b). vortex turbines; b). tachometers; c). permanent magnet generators; e). kiprok; f). avometer. Testing the prototype of the picohydro power plant is carried out by measuring the voltage produced by the generator, using variations in the opening of the water flow of 50%, 75%, 100% to find the maximum rotation, and tested without load, and when coupled generator, generator-load. Based on the results of the PLTPH performance test, the largest opening produces maximum performance. The results of the no-load test with a coupled generator, the voltage is 57.5 Volts DC obtained when the valve opening is 100%, at a discharging of 30.9 L/s, rotation N(1) 104.8 rpm, (N2) 499 rpm. The output of the generator with the battery connected to the load is 30.6 Volts DC, with rotation (N1) 78.2 rpm, (N2) 373 rpm, and a current of 38.3 A and has an efficiency of 58.5%.
