Conclusions
-
1.
Prototype cavitation investigations of operating turbines permit introducing well-founded corrections into the permissible operating regimes of such units at hydroelectric stations, increasing their operating and installed capacity in a number of cases.
-
2.
The method of prototype cavitation investigations, developed at the Central Boiler and Turbine Research, Planning, and Design Institute (TsKTI), permits establishing realistic operating limitations for units on the basis of not only a deterioration of their indices but also development of cavitation erosion.
