Purpose. For the design of impellers of Kaplan turbines.
Specifications. The maximum calculated efficiency of the full-scale flow path is 95.97% at a power of 32.424 MW.
Application area. Energy. HPS.
Advantages. The value of efficiency and power in the modernized flow path is higher than that of the original one, in almost the entire range of HPP pressures. For example, in the design head on modern turbines of the Kremenchug HPP, the maximum efficiency is 0.87% higher, and the power is 0.516 MW higher.
Description. A new impeller vane system PL20/5251 with improved energy characteristics has been developed: the maximum calculated efficiency of the full-scale flow path.
