Development of Pumping-type for Turgo Impulse Micro Hydroelectric System in Emergency Power Supply

In this work, a turgo impulse micro hydropower plant was developed by using the water flow in a natural pipeline to prepare emergency power supply at disaster sites. A motorized ball valve was used experimentally to control the water volume as it changed to output voltage under various water column conditions, including 4.5 m, 6.0 m and 8.0 m. To obtain the results, the effect of water pressure drop as a function of flow rate was investigated water flow, speed and output voltage. Please remember that the number of revolutions has a significant impact on the power generator. It was found that the load power produced would vary depending on the load resistance. It was mentioned that as the number of revolutions increases, the output voltage will increase, which presents a maximum voltage of 78 V, revolutions of 1035 min -1 and water flow of 583.3 x 10-3 m3/s after 8.0 m of water column. And for the water column set at 4.5 m and 6.0 m, the output voltage was shown to be 53 V and 63 V, respectively. As a result, the optimal result was obtained by a water column of 8.0 m, which showed the highest power of about 5.0 W when used for charging mobile phones.
