The present invention relates to a hydroelectric power station with at least one upper storage, at least one lower memory and at least one flow path interconnecting the two memories, at least one water turbine is arranged inside of it.

use of water power plants, irrespective of their type (storage power plant, raftwerk run, tidal power station), the respective potential difference between an upper water and underwater. An outstanding advantage of hydroelectric power plants is the excellent availability and controllability. Hydropower plants can almost go without delay to the grid, which makes them particularly suitable to cover peak loads in a short-term power demand occurring. However, a disadvantage of hydroelectric power plants are the considerable cost of transporting .of the current supplied to the consumers; because natural hydropower potentials are usually far away from urban areas, namely almost exclusively in little or no populated country strokes.

The present invention has set itself the goal of making the water power independent of the natural terrain topography usable.

This object is achieved according to the present invention in that the hydroelectric plant of the aforementioned type forms a block-like structural unit by the upper and lower memory and the flow path are formed by cavities of a closed structure. In other words, in the Inventions use of water power plant not only the lower memory with the upper memory connecting flow is away by a (artificial) structure is formed; Rather, the upper and lower memory are in that they are formed by cavities of a closed structure itself together with the interconnecting flow path portion of a block-like structural unit. This construction of the hydroelectric plant allows a previously unimaginable flexibility in terms of localization of hydroelectric plants. Because the invention makes the location of hydroelectric power plants in particular, completely independent of specific topographical conditions. Just so far hardly or not populated, more or less untouched mountain landscape need not be destroyed at the facility of hydropower plants and / or for backing up of reservoirs. The invention also enables the construction of hydroelectric power stations close to consumers and / or taking into account particularly favorable from approval conditions. Ideally, the invention as part of the reclamation of interventions from mining (surface or underground) can be realized. In this context it is important that can be hydroelectric power plants by the present invention a particularly compact and space-saving run, so that a particularly high performance can be installed on a given base.

According to a first preferred development, at least a machine room is provided in the inventive hydroelectric power plant, which is also formed by a cavity of the closed structure and accommodates at least one overall coupled with the at least one turbine generator. Such a machine room, for example, annularly surrounding the flow path of the two memory interconnecting. This is especially true if, as in correspondence with a further preferred development of the invention, the upper memory is arranged vertically above the lower memory. In this case, the two memories can be aligned interconnecting flow path in order to minimize the flow losses in the substantially vertical. The at least one machine room disposed annularly around this flow path, the result is a particularly favorable under static aspects shape. Against the same background, it is particularly advantageous if the lower and upper memory each have an axially symmetrical shape.

The fact that in the inventive hydroelectric power plant, the two storage cavities are formed by a closed structure, allows for the targeted influencing of the pressure prevailing in the storing pressure conditions. In this sense, the invention can be provided according to yet another preferred development that a system for increasing the pressure and / or pressure reduction is connected to the upper pressure-tight running memory. This system allows to increase the pressure prevailing in the upper tank above the water level pressure over the atmospheric pressure beyond what draws an increase in standing at the turbine available power by itself, or the pressure prevailing in the upper memory above the water pressure under the lower atmospheric pressure, which - reducing the power consumed by the at least one pump unit power - during the memory operation of a power plant is designed as a pumped storage power plant according to the present invention.

the possible by the present invention, integration of existing hydroelectric power plants in the cavities of the crust (mining) has already been mentioned above. Is in this sense that the closed structure forming block-like structural unit more or less submerged in the soil, so that its upper edge closes more or less with the natural ground surface, then the surface of the structural unit can according to yet another preferred development of the invention use as a stand for other structurally facilities. Particularly preferred additive means for generating electrical and / or mechanical energy are disposed on the surface of the hydroelectric plant according to the invention, such as solar and / or wind turbines. This is especially true if, as is provided according to a further preferred development of the invention, water power plant according to the invention is designed as a pumped storage power plant, by the lower and upper memory are connected to each other via at least one pump unit. In this case arranged on the surface of the hydroelectric power plant additive means for generating electrical and / or mechanical energy preferably serve to drive the pump unit, with which more or less continuously from the lower water storage is supported in the upper memory. The turbines of the hydroelectric power plant will contrast applied only to meet peak demand with water. In this way, a particularly environmentally friendly, landscape acceptable peak load power plant produces. Is in the meaning set forth above, the inventiveness modern hydroelectric power plant designed as a pumped storage power plant, a geothermal miekomplex may be attached to this in particular, with which the geothermal energy to generate driving power for the pump unit is implemented.

Also an electrolysis station may be attached for generation of hydrogen on the inventive hydroelectric power plant. Yet another preferred embodiment of the invention is characterized in that the at least one lower memory comprises a plurality of compartments which are filled during power operation of the power station one after another. The individual compartments can there be but located on the same or a different level. In that the individual compartments of each lower memory are connected to the associated flow path in succession, namely, the second only if the first is completely filled, can reduce the memory operation used to pump the water from the lower storage in upper memory. The same applies if the bottom of the lower reservoir is formed by a raisable and lowerable bottom which is supported for example by a spring means. Depending on the existing amount of water in the lower memory of the bottom takes up automatically such a position a, that the water level in the lower store directly below the turbine.
