Experimental Studies of Micro-Hydropower Plants with Siphon Water Intake

During experiments, a micro-hydropower plant with a siphon water intake and an orthogonal turbine with five-bladed runners with an installed capacity of 30 kW was tested, and the characteristics of the power equipment in the available pressure and flow ranges were obtained. A series of theoretical and field studies on the use of free-flow orthogonal turbines in small hydropower was conducted, and possible layouts were considered. The results of tests of the orthogonal turbine of the experimental microhydropower plant were analyzed, and its efficiency and the operating conditions of the hydropower equipment in which cavitation occurs were determined.
