Experimental investigations of the model and operating plant of the portable micro-HES with a siphon water conduit
The purpose of the investigation is searching of optimal design decisions of flow supply to a micro-HES. In order to determine the flow rate of water at a micro-hydroelectric power station with an orthogonal turbine as a working unit and with a siphon conduit at the “Khorobrovsky” hydroelectric complex, the method of centrifugal force was chosen. In the course of the work there were carried out a number of preliminary tests of a portable micro-hydroelectric power station with a siphon water conduit and an orthogonal turbine with five bladed impellers of the installed capacity of 30 kW. The characteristics of the power equipment were obtained in the available pressure and flow ranges in a series of tests. A series of theoretical and field studies on the use of free-flow orthogonal turbines in small hydropower was fulfilled. The test results of the orthogonal turbine of the experimental micro-hydroelectric station were analyzed, its efficiency rate was determined, as well as the operating modes of the hydro-power equipment in which cavitation occur.
