METHOD TO CONSTRUCT SEISMIC-SAFE HYDRAULIC POWER PLANTS THAT PROTECT RIVERS AND ENVIRONMENT Russian patent published in 2014 - IPC E02B9/00 F03B13/00 

FIELD: construction.

SUBSTANCE: invention relates to hydraulic engineering and may be used in construction of hydraulic power plants in any area. The method includes construction of a cascade of water reservoirs with small capacity that are built at side river affluents, in area folds or in ravines, aside from the main river bed. Water reservoirs and their dams are arranged at one or both sides of the river at such distance from each other so that water horizons of each subsequent water reservoir of the cascade, starting from the river head, are lower than the bottom of the previous one. All water reservoirs of the cascade are connected to each other by discharge water conduits, water intakes of which are arranged in the lowest points of the dam of the previous water reservoir, and the end, with a hydraulic turbines or hydraulic turbines, for instance, active, cone and generators, on the dam or shores of the subsequent water reservoir, with drainage of water in it from the turbines. The first water intake of the HPP cascade is made, for instance, as a side one from the main river bed.

EFFECT: invention provides for river protection as an HPP is constructed on it in its original form, reduced adverse effects from water reservoirs, preserved ecology of the area, where the HPP is being built, provides for the possibility to obtain high HPP capacities from the river without accumulation of high amount of water in water reservoirs, and elimination of domino effect in damage of one or several dams of the HPP cascade.
