Perencanaan Turbin Air Mikro Hidro Jenis Pelton Untuk Pembangkit Listrik Di Desa Kali Kecamatan Pineleng Dengan Head 12 Meter

The utilization of water as a natural resource of renewable energy for power plant is one of the alternative solutions to replace the need for fossil fuels. there is a waterfall on the river which through Kali village in Pineleng district, From observations and the calculation speed of the flow by using buoys, and river cross-sectional area obtained the total river debit Q = 0.323 m3 / s. From the measurements is also obtained high fall the waterfall H = 12 m. Based on the existing height and debit of the water fall the major dimensions of a water turbine Pelton Micro Hydro type as the driving power generator was planned. The results of calculations for effective head = 12 m, with a water debit that is used to drive the runners Q = 0.06 m3/s, gained power generated by 4.0 kW. By the data is planned the main dimensions of micro turbine Pelton outer runner diameter Do = 380.8 mm, the diameter of the circle pin D = 202 ​​mm, number of bowls z = 19 with 1 nozzle, and a shaft diameter ds = 45 mm

Performansi Pompa Air Dab Type Db-125b Yang Difungsikan Sebagai Turbin Air

The use of water pumps DAB type DB-125 as the impulse turbine functions for Micro Hydro Power Plant Lisrik (PLTMH) is the topic in this research. Water pump is used to suck water and deliver it to a certain height. In this application the water pumps used as turbines where water from a certain height will rotate the impeller pump and produces electricity. The testing is done in the laboratory of mechanical engineering of University of Sam Ratulangi. Turbine is driven by three pumps which are assembled in series and parallel, to get different head and flow (Q). Water flow and load on dinamometer ( ) have been set at the lowest rotation of the load on turbine. For the initial set of water flow Q = 33,5 litres/minute. The results showed that the different H and Q from curve turbine rounds, maximum power is at Q = 40 litres/minute, H = 33,5 m, and n = 910 rp
