The invention relates to hydropower and can be used to generate electricity in the mountain rivers or rivers with a large level difference along the bed and a big difference in the volume of the channel in the summer without breaking the hydrological characteristics of the river and the ecology of the river and adjacent areas.
Known dam hydroelectric power plant with an intermediate reservoir, including penstock with water intake in the river and shutter, while the penstock has a slope less than the slope of the bottom of the river, and connects the intake to the intermediate tank. The intermediate tank equipped with a turbine conduit connected with the shaft of the generator and the stator flux, made in the form of walls with holes, separating the discharge conduit and the turbine conduit (see patent RU No. 2162914, MPK-7 EV 9/00, F03B 13/00).
The closest technical solution to the proposed dam is a hydroelectric power station with an intermediate tank which contains the water - reservoir, located upstream of the river and placed outside of the river channel, penstock connecting the inlet from the intermediate reservoir-tower, which houses the damper is attached to the inner wall of the tank as well of reinforced concrete rings, a tubular outlet, the water inlet to the water turbine, and the turbine, Vasanas shaft of the generator (see patent RU No. 2381329, IPC EV 9/00).
The disadvantages of the known technical solutions is the low efficiency, due to the fact that the length of the pressure conduit is limited by the height of the tower HPP, and the fact that water covers a small part of the waters, because HES consumes a limited amount of water from the volume to the minimum level of the river for hydro turbines and all the water during the deposition of high rainfall and the melting of glaciers goes on the main river channel, Potapova surrounding area.
The technical result of the claimed technical solution is to increase the efficiency of hydroelectric power due to the expansion of the catchment area, covering the volume of flood waters across the river and controlled flow rate cumulative volume of flood waters and by applying pressure conduit at the site of the maximum differential level of the river.
The technical result is achieved by the fact that the diversion dam hydroelectric power plant with a pressurized water conduit containing water located outside the river channel, the main tank, penstock and turbine conduit, contains the n-th number of regulatory reservoirs to collect water, placed all along the river, each of which is provided with a channel fill, connected to the river channel in the top level place, and the dam is the height to the top level, made in the lower level of his place, and at the bottom of each regulating reservoir has a release pipeline which is connected with the river bed and is equipped with a shutter, while the main tank is made in the form of the main reservoir located below the regulatory reservoirs on the plot with a large difference of level of the river and provided with a channel fill, connected with the river and the dam to the upper level, performed respectively in the upper and lower level areas, and the discharge conduit installed below the level of the main reservoir and is made in the form of pressure pipelines with length not less than 12-15 km depending on the level difference river for a given pressure coming from the main reservoir, namely in the form of winter discharge pipe for the minimum consumption of water and n number of penstocks for summer maximum flow connected to the conduit turbines, hydroelectric contains a compensation reservoir, located at the level of the pressure conduit turbines connected to the conduit of the turbine and provided with a pump unit.

When the river runs with the increased load, maintained its high level, which is regulated by heavy rainfall discharge of the water in the regulating reservoir through the fill, eliminating flooding of adjacent areas. In addition, maintaining a high level of the river and the preservation of the river lead to the increase in the number of fish and increase fish spawning, while improving the ecology of the river due to sediment water regulating reservoirs.
The basic capacity of the main reservoir located below the regulatory reservoirs and on the plot with a large difference of level of the river with channel filling, connected with the river and the dam height to the top is about level, performed respectively in the upper and lower level areas, and placing pressure conduit below the level of the main reservoir and is made in the form of pressure pipelines with length not less than 12-15 km depending on the difference of level of the river for a given pressure coming from the main reservoir, namely in the form of winter discharge pipe for the minimum consumption of water and n number of penstocks for summer maximum flow connected to the conduit of the turbine, as well as the supply of hydroelectric power compensation reservoir, situated at the level of the pressure conduit turbines connected to the conduit of the turbine and provided with a pump unit, allows to keep a constant pressure and to adjust the load on the turbine by means of the pumping station associated with compensation reservoir, increasing efficiency, because at the lowest load consumption in the network part of the volume of water pumped to the compensation reservoir and can be used when the load increases consumption.
In addition, the length of the pressure pipe reduces the amount of flood-prone areas, keeping the river, improving the ecology of the river.

Diversion dam hydroelectric power plant with a pressurized pipeline works as follows.
On a roll of heavy rainfall in the summer and snow melt water from the overflowing of the river channel by channel 2 of the filling goes in regulating reservoir 1, filling them, and the gates of the drain pipes regulating reservoirs are closed. Overflow regulating reservoirs open the gates of the drain pipe and drain the water in the river channel, adjusting the level in them. When the message forecasters of heavy precipitation from regulating reservoirs in this area is also drained the water, freeing them for adoption of the new water and direct it to the turbine through the main reservoir, penstocks and penstock turbine to generate electricity. When working dam hydroelectric collect all flood waters and a controlled flow of water from the regulating reservoir for feeding into the main reservoir and discharge lines to the turbine connected to the shaft of the generator. To adjust the load consumption of the turbine and reduce the inertia of the system of water conduits use the compensating reservoir with pump group. When the load increases consumption off pump group applying the drain water to the compensation reservoir, and its power is translated n the consumer, and Vice-versa. Water supply from the expansion reservoir to the turbine provide a controlled flow of water from the regulatory bodies of water, compensating for their inertia.
Combining several declare dam power plants of several rivers in a single system will allow you to effectively and consistently to produce electricity without damaging the environment.
