Description
Summary:Hydropower plants (HPPs) contribute a significant share of Russia’s electricity generation. With the prospects of developing this sector and harnessing the hydroenergy potential, it is necessary to consider methods for modernizing hydroelectric installations. This article examines a new method for regulating active (Pelton) turbines based on modifying the nozzle flow rate through the ejection of spent liquid from the runner using a jet pump. The relevance of this solution lies in the potential to increase the operational duration of high-head pumped-storage hydropower plants (PSHPPs) and improve reliability by eliminating or reducing the intensity of operation of the regulating needle in the guide apparatus. Various structural configurations for incorporating the jet pump into the hydrosystem of HPPs/PSHPPs with Pelton hydro turbines are discussed. Parallel and series configurations offer specific advantages and disadvantages. A methodology for determining the expression to calculate the parameters of the injecting device, depending on the turbine’s characteristics, is presented based on a mathematical model of the jet pump with a central nozzle.
