Control of the conditions for input of hydropower into the unified power system of the USSR

Conclusions

• 1. The main regulators of hydropower in the UPS will be the Angara-Enisei cascade and the Turukhan hydrostation. The latter will play the principal role in stabilizing the input of hydropower into the UPS in the long haul and in providing its annual distribution in the interests of the power industry while satisfying the requirements of nonpower water consumers.

• 2. The joint operation of the Volga-Kama and Angara-Enisei cascades iois expedient: in this case it will become possible to increase the total firm power of the hydrostations by 13% and to use the free capacity of the Angara-Enisei cascade at the peak of the load curve of the UPS and also to increase the firm production by 8%.

• 3. A large increase of firm production is achieved by compensating the annual and long-term nonuniformity of production of hydrostations of the Volga-Kama cascade by the production of the Turukhan hydrostation. Unification of the Turukhan hydrostation with the Angara-Enisei cascade, in view of high regulation of production of the latter, is less effective. In both cases the Turukhan hydrostation has a stabilizing effect on the input of hydropower into the UPS. The annual distribution of hydropower will become most favorable for the UPS.

• 4. Realization of the combined operation in a regime of compensated regulation of the Volga-Kama and Angara-Enisei cascades and Turukhan hydrostation makes it possible to achieve in the winter constancy of production of the hydrostations practically during the entire long-term series, i.e., to make it independent of variability of river runoff.

• 5. Taking account the high cost effectiveness of constructing the Turukhan hydrostation and intersystem connections between the European part of the UPS and Siberia, planning agencies should accelerate the solution of these problems.
