Electrical Power Analysis of Generator Driven by Cross-Flow Turbine of Micro Hydro Power Plant (Mhpp)

Abstract

Micro hydro power plants use differences in height and water discharge, this flow is used to rotate the turbine to produce mechanical energy which is then used to drive the generator to produce electricity. Micro hydro power plants emerge as an environmentally friendly and affordable energy solution, especially in rural areas. The purpose of the study was to determine the generator rotation speed, to find out the electrical power produced to find out the efficiency of the generator power. The method used in this study is an experimental method with direct experiments in the field through four stages including preparation, design, manufacture, and testing of the tool. In this study, three variations of the blade were used, namely blades with a number of 6, 9 and 12. The parameters measured such as the rotation of the power generator pulley, voltage, current, and generator efficiency. The results of this study can be seen where previously three variations of the blade were used, namely, blades with a number of 6, 9 and 12. The voltage test obtained an input power of 2.1 volts on blade 12, while the lowest voltage was recorded at 0.6 volts on blade 6 while on blade 9 it produced 1.2 volts. The best efficiency on the 6th blade is with a value of 86%. The conclusion of this study is that the water flow causes an increase in voltage which is triggered by an increase in generator rotation. Generator power is greatly influenced by the decrease in the blade angle on generator performance, Efficiency is influenced by cable resistance, this phenomenon is known as voltage drop.
