Performance analysis of pico domestic technology hydroelectric turbine sets

The development of clean energy technology worldwide has sparked significant interest in the production of very small hydroelectric power. This article discusses the impact of various parameters, including the diameter of the nozzle, flow rate, and head level, on the performance of a 3 kW KIRIWONG turbine, a domestically produced hydroelectric turbine, through testing methods. The study found that the maximum electrical power and efficiency produced are linearly related to the flow rate, with the ability to produce 3 kW of electricity at a head level of 100 m and a flow rate of 5.05 l/s, translating to an energy conversion efficiency of 60.5% from water to electricity. It also identified a negative correlation between the nozzle diameter size and the turbine's efficiency, which can be used as information for the design and development of more efficient small hydroelectric turbine systems in the future.
