Abstract

Tropical area has two seasons, which are rainy and dry seasons. In the rainy season. In the rainy season, the river flows a large amount of water, usually causing flood, conversely, the river shrinks in the dry season. The Excess water can be used to turn turbines. Turbine which is used to turn the generator will produce electric energy. To generate electrical energy in a long time with the condition of the changing seasons, an efficient turbine is required beside the water level, pressure and diameter of the turbine should be considered. In this paper we discus the turbine bowl angle settings to get the maximum volume of water to produce maximum torque of the turbine. With level of water 17 meter, the transmission pulley 4 step, produce rotation of turbine 23-25 rpm, rotation rate of the the generator is 1500 rpm. By using the Matlab simulation, volume turbine bowl will maximum at 5.574 cm3 calculated by angle theta 11 degrees and alpha 9 degrees. Thus, these conditions produce the greatest torque. The Micro hydro in Dusun Gambuk Pupuan Tabanan Bali [19], [20] now only produces power of 700 watts, then by adjustments angel bowl of turbine generated electricity double before now about 1400 Watt.
