Design of a prime mover turbine propeller open flume micro-hydro electric power plant 1 kW

Abstract

West Java has many rivers that have high falls and varied water discharges where utilization is not optimal. The study aims to utilize water energy to be able to produce a Micro Hydroelectric energy generator. The design of this PLTMH starts from measuring the potential of water, designing turbines and generators, then observing the work system of PLTMH and estimating the electric power that will be generated by the PLTMH. From chosen location, it is known that the water flow is 0.0059 cubic per second and has a waterfall height of 4 meter. This data is used to select the type of turbine, selection of reservoirs, rapid piping, and generator design. The results obtained by the design of Micro Hydro Power Plant (PLTMH) using open flume propeller turbines and 3-phase generators are changed to 1 phase. Open flume propeller turbines have a simple construction and can be operated at a waterfall height of 3-6 meters and low water discharge so that the use of open flume turbines for micro-hydro power plants will be used in river flows that have high waterfall and water discharge the low one is very appropriate. With a turbine rotation speed of 2,063 rpm, this PLTMH is capable of producing 1,346 watt turbine power with a 45 liter per second water flow so that the power obtained is 1,076 watt.
