The invention relates to a hydroelectric power plants (HPP), which converts the mechanical energy of water flow into electrical energy through hydraulic turbines, resulting in a rotation of the electric synchronous generators.

Known hydropower that converts the mechanical energy of water flow, accumulated by a Weir installed across the river. The energy of the accumulated water under pressure, determined by the level of the dam, is sent to the turbine, the rotating shaft of the synchronous generators, which provide at its output power to the required voltage. This hydroelectric power plant requires for its functioning complete large amount of excavation and construction works [Hydroelectric station. Edited by Gubin FF M.: Energy, 1980].

The disadvantage of this HPP is a large amount of construction and earthworks and the inability to pass water transport in both directions, and the resulting reservoir occupies a large area with a large coastline, requiring expensive care and maintenance.

Also known tidal hydroelectric power plant (TPP) [Hydropower plant (hydroelectric power plants, pumping stations and pumped storage plant). Edited by Oxalic DS. Leningrad, Energoatomizdat, 1981. P.40-41], which converts the energy of sea tidal and flows into electrical energy. Existing PES (1985) - in the estuary rrans in France and lip acid to the Barents sea in the Russian Federation.

PES contains outdoor switchgear, shipping gateway, the building of PES with synchronous generators bulb hydro turbine, an earthen dam, a separate abutment on the remaining part of the reef, spillway dam.

The construction of all these parts is very labor intensive, and the work of the PES due to the periodicity of the tides is intermittent, the power of such PES are of small size.

The objective of the invention is to reduce the complexity of the construction of hydroelectric power stations, ensuring continuity and unlimited increase in electrical power.

This task is achieved by the fact that hydroelectric power plant, comprising an open switchgear, generators, synchronous horizontal bulb turbine placed in the intensive flow of water entered the platform-base, a vertical rack-rails, lifting mechanism and the open distribution system, as specified synchronous generators combined in at least two vertical areal cell-capsule system and suspended in pairs and movable with tripping mechanism to the rack-rails above and below the water surface, the lower ends of these article is EC-guides mounted on the platform-base at the bottom of intensive water flow, areal cell-capsule system synchronous generators are installed movably in the guide associated with the bottom of the anchor-rope fastenings above the water surface on the guides installed outdoor switchgear. Such hydropower plants can be set arbitrarily many in the length, width, depth, which can be integrated into a power grid.

In the drawing given cross-section of the proposed hydroelectric.

Hydroelectric contains at least two installed on top of each other or next to each other in series and (or) parallel (horizontally and vertically) areal system 1, 2 capsule hydrogenerators [see, for example, GOST 5.219-72. The synchronous generator horizontal bulb turbine type SGK-538/160-70]. These capsule system of generators of flexible cables or chains 3, 4 are driven tripping mechanism 5 mounted on the top of the main bearing 6, its lower end driven through the base 7 in the setup hydroelectric power plants with intensive water flow. System capsule hydrogenerators movably installed between the support 6 and the supporting legs 8, 9. The main and auxiliary supports are provided with rods 10 with anchor fasteners 11 to the bottom of the reservoir on both sides of hydroelectric power plants On the water surface at the required height to the supports 6, 8, 9 fixed loading platform 12 with the necessary technological equipment open distribution device 13 for the normal functioning and maintenance of hydroelectric power.

Hydroelectric power plant operates as follows.

Select the place of installation of the hydroelectric power plants with intensive water flow. It may be a river, ocean or sea current. For example, ocean Gulf stream has a flow of more than 20 water flow of all the rivers of the globe, the flow velocity of the water flow up to 6-10 km/h, which is quite enough for normal work capsule hydrogenerators that allows you to create hydroelectric almost unlimited power.

The selected site is first installed base 7, is pressed into the bottom bearing-pile 6, are mounted the supporting rails 8, 9, is then made secure fastening to the bottom using a cable linkage anchors 10, 11 poles piles 6, 8, 9, built a technological platform 12, is set tripping mechanism 5 with cables-chains 3, 4, which in turn are fixed capsule generators of series 1 and 2. Set the necessary technological equipment open distribution device 13. To hydroelectric power is supplied cable or overhead power lines. Going by the wiring diagram of Hydra the generators and their alternate start when diving hydrogenerators 2 to the desired depth. When this synchronous generators 1 tripping mechanism 5 rise to the surface above the water level and performs the necessary periodic maintenance operations and their treatment. The latter is very important when installing a hydroelectric power plant in warm ocean waters

This implementation of hydropower has minimal complexity due to the lack of earthworks during the construction of dams and hydroelectric power due to the inclusion of an unlimited number of generators can be arbitrarily large, forming areal cell-modular system, the construction of a number of hydroelectric power station on the depth, length and (or) in several rows and simultaneously ensures a continuous (uniform) mode of operation.

When the dimensions of, for example, capsule hydrogenerator (diameter of 6.1 m length 15 m, the mass of 166 tons, the capacity is 19.9 MVA), you can create a capsule system 10×10=100 generators with dimensions of 100×100 m power of 2.0 MW, which is comparable with the most powerful hydroelectric power plants in the Russian Federation (Krasnoyarsk HPP - 6 GW, the Sayano-Shushenskaya hydroelectric power station is 6.5 GW). The construction of such proposed constructions HPP much cheaper and many times less costly than the construction of traditional hydroelectric dams on the rivers. The construction will be minimal, not comparable with years of traditional construction of a dam stations. At last the m data, the construction of a dam across the Yangtze river (China) at a cost of 25 billion US dollars. For the same amount it is possible to build more than a dozen proposed, in the case of construction on ocean currents, ocean HPP (ASPP).

Two sets of cassette generators 1, 2 is required for periodic maintenance, repair and periodic cleaning, especially when set in the warm currents of the oceans.

The construction of HPPs on the proposed design scheme does not require the construction of swimming pools, dams, buildings, hydro and does not require performing any excavation, which further reduces the time of their construction and during the construction requires minimum user input.

Hydroelectric power plant, comprising an open switchgear, generators, synchronous horizontal bulb turbine placed in the intensive flow of water, characterized in that the hydroelectric introduced platform-base, a vertical rack-rails, lifting mechanism and technology platform, and these synchronous generators are combined, at least two vertical areal cell-capsule system and suspended in pairs and is movable above and/or below the water surface using a tripping mechanism to the rack-rails, the lower ends of these rack-rails mounted on the platform-base installed on the bottom intenzivnog the water flow, areal cell-capsule system synchronous generators are installed movably in the guide associated with the bottom of the anchor-rope fastenings, and above the water surface on the guides installed outdoor switchgear.
