Selection and standardization of hydraulic turbogenerators for the Lower Kama and Cheboksary hydropower plants

Conclusions

Standardization of the turbogenerators for the Lower Kama and Cheboksary plants is an effective measure which enables:

• a) the capital expenditure on the two plants to be reduced by about 3.4 million rubles;

• b) the labor input to be reduced and the utilization of equipment to be improved at the works engaged in the manufacture of the standardized units;

• c) identical scroll casings to be designed for both plants, the service cranes in the machine halls and the auxiliary-equipment systems to be standardized;

• d) practically equivalent overall dimensions and arrangements to be adopted for the hydrotechnical parts of the power-station building blocks, and of the layouts of the turbogenerator units, thus reducing the design effort on the two stations.

Standardization of the hydropower equipment can be recommended for hydroelectric plants which have nearly the same head and are on rivers with comparable flow characteristics.
