description: While replacing hydroturbine equipment it is necessary that the energy qualities of the machine improve, i.e. either power or energy output increases. Most of the time units will work in the peak of the schedule, and the option to replace the equipment must be selected by the criterion of obtaining maximum capacity (maximum peak power). Subject of graduate qualification work: "The choice of a new turbine impeller on the conditions of Nizhny Novgorod hydroelectric power station". The object of the research is Nizhegorodskaya HPP. The subject of the study is the choice of the wheel on the conditions of Nizhny Novgorod HPP. This work is concerned with building operational characteristics of the turbine and the choice of a new impeller under the given characteristics During work the following tasks were solved: 1. Setting the reasons of turbines replacement; 2. Construction of 3 operational characteristics; 3. Analysis and comparison of the obtained characteristics; 4. Increase of turbine capacity taking into account cavitation working conditions.
