Testing of a Micro Hydro Power Plant Using a Cross-Flow Type Turbine

The implementation of Micro Hydro Power Plants (MHPP) serves as a crucial initiative to address the uneven distribution of electrical energy in remote areas across Indonesia. Before the permanent installation of an MHPP, field testing is imperative, involving the use of a model or prototype to gather location -specific data, assess reliability, and enhance insights into the MHPP's functionality as an electrical energy generator. This research endeavors to comprehend the operation of the Cross -flow turbine MHPP system and ascertain its output power and efficiency. The testing process commences with the design of field test equipment, followed by manufacturing and assembly stages. Subsequently, equipment testing and data collection are conducted, and the obtained data is analyzed to determine the output power and efficiency of the MHPP system utilizing a Cross -flow turbine. The test parameters include water flow, head, turbine input power, generator output power, and overall MHPP system efficiency. Upon analyzing the results and engaging in discussions, it can be concluded that the test considered crucial parameters such as water flow, head, turbine input power, generator output power, and MHPP system efficiency. The highest efficiency recorded was under variable load conditions with a fluctuating discharge of approximately 0.025 m(3) /s, achieving 1.39% efficiency at a load of 80 W. The research findings indicate that variations in head and discharge significantly impact the efficiency of the MHPP system.
