Ukraine has sufficient potential for the development of renewable energy sources. Renewable energy of our country is actively developing. The
demand for accumulating hydropower services will grow. This is due to the requirements of modern energy systems to align the schedule for operation
in peak load zones. The solution to the problem of creating highly efficient equipment for pumped storage power plants largely depends on the correct
selection of the geometry of the water passage elements of the reversible machine, which provide the required level of its energy parameters. The
paper deals with the issues of modeling the hydrodynamic characteristics of the blade systems of a reversible hydraulic machine. Changes in energy
parameters in the range of basic operating modes of the hill-chart are largely due to changes in the hydrodynamic characteristics of a reversible
hydraulic machine. The general approach to describing the hydrodynamic characteristics of blade systems is based on the use of dimensionless
parameters characterizing the flow in the characteristic section of the water passage. Expressions, which establish the relationship between the
hydrodynamic characteristics and dimensionless complexes and express the general laws of the interaction of the flow with the runner of a reversible
machine, are given. The influence of the hydrodynamic parameters of blade systems on the formation of the energy characteristics of a reversible
hydraulic machine is considered. Analysis of the hydrodynamic characteristics of individual elements of the water passage allows to analyze their
influence on the energy characteristics of a reversible hydraulic machine. The results of such an analysis are the basis for solving a wide range of
issues that arise when designing a reversible hydraulic machine. This paper presents the calculations of the energy characteristics for the water
passages of reversible hydraulic machines ORO200, ORO500. The calculated data indicate the decisive influence of the hydrodynamic parameters of
the spatial lattice on the parameters of the optimal regime.
