摘要：

The results of changes in the thermal efficiency of high-pressure cylinders (HPC) of active and reactive types, as well as intermediate-pressure cylinders (IPC) with stages of an improved design of turbines with a capacity of 300 MW produced by LMZ during long-term operation are presented on the example of Konakovskaya regional hydroelectric power plant (GRES). Recommendations are made regarding the possible use of the proposed technical solutions in power plants with similar turbines. © 2023, Springer Science+Business Media, LLC, part of Springer Nature.
