Abstract

The invention relates to a pumped-storage power plant type which is set up predominantly in seas. The core of the storage power plant comprises vertically superimposed chambers, with which "filling and emptying processes" of the water medium can be effected in order to create potential energy or a head, and to produce electricity therefrom. The upper chambers are connected to the lower chambers via controllable flow channels, through which water turbines in the lower chambers can be impinged upon to drive electrical generators for outputting electrical energy in the form of current. The store is filled in that water pumps driven by electric motors pump water from the lower chambers into the sea, whereby the conversion into potential energy of the water in the upper store is effected from the supplied current for storing the electric energy, minus efficiency losses, for the water pumps. The pumped-storage power plants in the sea preferably offer the necessary storage capabilities for alternative power plants such as wind farms or solar farms of all types, without having to consider shortages of water medium.

Description

Offshore pumped storage power plant

The invention relates to a pumped-storage power plant according to claim 1 and the following claims, which is primarily located in waters, in the sea and as an energy store, z. can serve as for wind farms and solar power plants of any kind.

Pumspeicher power plants in the country are known as prior art to store surplus electricity into potential energy by means of the medium water for later use with a certain efficiency discount for more than a century. The water is pumped by pumping to a higher geodetic height in a memory, or in a higher-lying lake. There is a high demand for electricity, which can not be immediately covered by the active power plants, the consumer is this potential energy over the head of water for conversion into the water turbine into mechanical work and coupled thereto electric generators for a rapid current demand available.

A major disadvantage of the known pumped storage power plants is the considerable space requirement, if there is a fully synthetic created power plant. Furthermore, the implementation of a pumped storage power plant often especially not correlated not with the interests of many groups, with the interests of nature conservation associations.

Despite the growing demand for electricity and the planned replacement of nuclear power plants with alternative power plants, in particular by wind and solar power plants of all kinds, there are significant problems from a political perspective the necessary storage technologies for advantageous grid stabilization enforce.

Also, there is a strong dependence of the present water-storage power plants from the action of the weather, or the events of the frequency of rain. in hot weather periods since a considerable evaporation rate is present and the waters in question usually play an important role for the supply of drinking water, it can cause serious water shortages that disrupt the memory process, or even make it temporarily impossible. we move from Europe in the areas that are widely around the equator, we find huge land areas that have a high potential of wind and solar energy for power generation. However, a simple storage of energy by the conventional pumped storage technologies can take place as a storage medium and the lack of necessary surveys in most cases because of the lack of water.

It is therefore an object of the invention to design a type of pumped storage power plants, which on the familiar, simple and conventional

physical principle is based, and neither space problems brings with it even in the foreseeable future scarcity of the main medium of water will have.

In addition to the clear physical conditions, then should the political conditions for the reactions of the storage type in the world not to be unfavorable. The energy conversion with alternative power plants will create an additional base which is associated with this simple memory technology. It is expected that under new favorable conditions with the developability of the simple memory technology breakthrough of alternative power supply without major political resistance is likely.

The problems are solved by the present invention pumped storage power station type with the features of claim 1, together with the claims 2 and 3. FIG. Advantageous embodiments of the alternative power plants with convenient and non-trivial further developments of the invention are in the dependent claims, where in particular with claim. 9

The essential feature of the vertically stacked chambers which are connected by flow channels, is the placement within waters, seas in particular within the core of off-shore storage power plants. By means of the two chambers one above the other, the base for generation of the drop heights-potential of the water required for this purpose. Since the pumped storage power plant is preferably located within the sea, there is virtually no time shortages at the central medium of water, which is necessary for energy storage here.

The location of the storage power station would be typically are home to small attitude of the transmission losses in the vicinity of alternative power plants, where to store the excess energy can then be conveniently located efficiency as an intermediate buffer ..

In the lower chambers, the arrangement of the water pump is made with the electric motors, which are driven by the current supplied by the respective power plants excess currents. The water pumps convey the water from the lower chambers through their discharge channel in the marine environment, thus providing space for the energy conversion of the geodetically higher water from the upper chamber.

The upper chambers would be in form of a version advantageously as low-scale production for in which the adjustable flow openings and supply lines and the distribution must be the case, channels which are connected to the lower large-volume chambers, housed. Thus, one could at the important parameters of the height of fall in the operating phases in which you retrieve from storage power plant in the form of electricity, almost always start from the surface of the water or the sea. In the lower large-volume chambers, the water surface increases as the quantities of water that flow through the trap passages over the water turbines, which results in a reduction of the height of fall during use of the stored energy results, which means an essential parameter in the interpretation of the type of power plant.

To be stored excess energy of the respective power plants, which relate to the current supply to the electric motors that drive the water pump in the lower chambers and are thereby used to create the height potential of the water then the from the sea by of valves or valves controlled openings geodetically higher level flows into the upper chambers,

now takes place, the requirement that the stored energy in the form is to deliver a power supply, the water turbines, which are also positioned in the lower chambers, pressurized by water from the upper chamber via the communication ports in the currently prevailing height of fall. The

Water turbines are coupled to the electrical generators that convert the mechanical power of the turbine into electrical energy. The transport of the electrical power of the generators is carried to different lines on which converters in the one or more networks, and is supplied to the consumer with the appropriate voltages.

Further advantages, features and details of the invention will become apparent from the following descriptions of several embodiments and from the drawings. The description above mentioned features and combinations of features as well as mentioned below in the figure description and / or separately shown in the figures features and combinations of features can be used not only in the respectively specified combination but also in other combinations or in isolation, without leaving the scope of the invention to leave. The figures show:

Fig. 1 is a schematic representation of the main components of the off-shore

Pumped storage power plant, wherein the open, upper chamber is designed kleinvolu- mig and contains the controllable opening and distribution devices for the inflowing water;

Fig. 2 is a schematic representation of the main components of the off-shore

Pumped storage power plant, wherein the open, upper chamber mig is formed as intermediate water storage großvolu-;

Fig. 3 is a representational sketched offshore pumped storage power plant in which the water in the intermediate water tank the upper

is flowing chamber with the valve closed the connecting channel and simultaneously water to "store filling" from the lower chamber pumped into the sea;

Fig. 4 is a representational sketched offshore pumping storage power plant in which is already largely filled intermediate water storage tank to the upper chamber as well as the lower chamber in the ongoing Beaufschlagungsphase of the water turbine with water, which is almost the empty state of the memory displays;

Fig. 5 is a representational sketched offshore pumping storage power plant in which the full intermediate-water storage tank to the upper chamber and the lower chamber contains a small water load and virtually indicating the maximum energy storage of potential water energy.

Fig. 1 shows the basic pump-Kraftwerkl with z. B. upwardly open chambers 2, the adjustable openings 8 with z. B. controllable

9 shifters include. The chambers 2 have the important task to keep their water surfaces 23 close to the geodetic height of the sea surface 22 as the upper Potenziafläche for the current height of fall largely constant. This means that the water flow rate from the ocean through the controllable apertures 8, and the valves and slide valves 9 cause in the open chambers 2 only minor reductions in the height of fall and thus the water surface 23 only slightly deviates from the sea surface 22nd

If the controllable valve 7 of the connecting passage 4 is opened, the charging of the water turbine 10 takes place with a drop height. 6 The director valve 7 Nesse save himself, if would be accomplished, the control for the water turbine operation through the controllable apertures 8 of the relatively kleinvolumingen chamber. 2

Thus, the water from the upper chamber 2 flows through the water turbine 10 and passes through the turbine outlet in the lower large-volume chamber 3 which defines on their length dimensions substantially the storage capacity of the pumped storage power plant. 1

One would like to a storage capacity of z. B. implement 100 MWh, it will at an intended average drop height of 6 z. B. 10 m and a lower

Chamber height of 10 meters also require an area of ​​about 3.7 x 10 ^ m ^, which corresponds to a length of about 610 m square. Are the boundary conditions for a very large drop height 6 100 m given the same chamber height, can

4 p

the storage volume and the space requirement on 3.7 x 10 m zehntein, which then corresponds to a square of length of less than 200 m for a 100 MWh memory.

The costs per MWh for the pumped storage power plant in the sea is highly dependent possibilities for a given storage volume of the dimensioning of the realizable drop heights 6, which is given by the extension of the sea surface 22 to the mean water surface 24 in the lower chamber. 3

The higher the specific power of the water turbine 10 constitute over the increased heights of fall, the smaller the space requirements of the power plant 1 will be. For changing the deeply placed storage chambers 3 to the connecting channel 4 then hardly to constitute a disturbance vessel traffic to the feed chamber in the second

To take into account 1, however, the control of the enormous buoyancy forces at the nominal storage energy are the Figure for the described Kaftwerksversion. (Chamber 3 largely exhausted) by the displaced water mass of the outer dimensions of the lower chamber 3 together with the tower of the connecting channels 4 and the further devices, the on the weights of the walls 19, the inventory, such as pump 12, electric motors 13, turbines 10 and generators 11 and any additional forces that have to be compensated based on the necessary anchors 21 on the seabed 30 to the position of the upper inlet of the water with respect to the chambers 2. to ensure a certain extent of the sea surface.

It is also conceivable that the pumped-storage power station of Fig. 1 is made variable in the distance from the seabed over apparatus and methods so that the water circuit of the storage plant in all operating phases of the "filling" as "emptying" and the changing conditions of the sea adaptable is. For this purpose are also conceivable not shown controllable openings 8 in the connecting channel 4 to the marine environment, which should be activated at the height changes of the power plant for the turbine operation.

As already mentioned, the potential energy in the water turbines 10 with the coupled electrical generator 11 taking into account the

Component efficiencies converted into electrical energy. The current generated is then discharged via the lines 27 to the network for the distribution to consumers.

Consists of the alternative power plants or via the network, a current surplus of current on the lines 26 is the electric motors 13 of the water pump accomplished 12 in the lower chamber 3 to the "filling" of the energy store by a pump out the water from the chamber. 3

The pumped-storage power plant according to the needs and constraints - "energy saving", "stream running in a predetermined amount" and -more process requirements - which are communicated 25 via the signals 29 of the power plant control, the respective signals 28 to the devices or Aktuato - ren of the relevant components such. B. valves 7, 9, 14, pumps and electric motors 12, 13 or water turbines and generators 10, 11 send out.

While the Schwimmbarkeit of the pumped storage power plant according to the characteristics in Fig. 1 in a few stages of operation is useful because of the small volume chamber 2 only partly and possibly larger forces on anchors and supports 21 must be applied in the sea floor, in the example of a conception that is outlined in Fig. 2 roughly in principle, the buoyancy of the pumped-storage power plant version in many phases of the modes significantly due to the larger chambers 2 and advantageous.

On the adaptability of the resulting force of the buoyancy by the displaced water mass with the counteracting force of the power plant weight, which can be changed by the inner volumes of water in the chambers 2 and 3, now consist here for the power plant 1, the options of buoyancy, the force-free floating state or that of the resultant force Sinkzustandes with a defined amount. These possibilities can be accomplished 8 and 14 by means of the regulating device 25 by regulating the internal quantities of water through the inlets and outlets by means of the manipulable openings. It is carried out in these regulatory processes of the adjustment of the average density of the entire power plant to the density of the surrounding body of water, as we know it comparatively with the submarines for a long time.

The power station 1 has in its degrees of freedom by management, waste support pillar and damping devices 20, because of the often harsh weather conditions defined exactly 21 despite the controllability essential forces in his local area.

The large chambers 2 can be considered with respect to the sea environment as an intermediate storage, the water based surfaces can 23 from the sea surface 22, the absolute height of fall 6 prozential differ markedly.

The large volume of the chambers 2, situated off the water fill rate advantage for the widespread use of the options mentioned in terms of swimming or floating capacity of the power plant. 1 Furthermore, the resultant forces can be characterized from the gravity and the buoyancy of the supports and damper 20 can be kept small adjustable 21st

The power plant 1 can be put together from many stand-alone modules mountable. A storage plant 1 with a storage capacity of 100 MWh Nesse to z. together racks B. 100 autonomous modules, each of 1 MWh, or interconnected. In this way, "Memory Park" could be developed gradually in the sea over many decades of immense sizes of the show to the growing storage requirements alternative or can also adjust the conventional power plants without space problems if necessary.. Figs. 3, 4 and 5 shows an objective sketched representation of a pumped storage power plant 1, and a power plant module in different operating phases of the memory with the core assemblies water pumps with electric motors 12, 13 and water turbines and generators 10.1 1, the valves 7.8, 14 and valves 9 which are controlled by the control 25th

The "filling" of the memory will be visible from the Fig. 3 with closed valve 7 of the connecting channel 4. The water pumps 12 are by the power plant excess current, for. Example, from neighboring wind farm, driven by the electric motors 13 by means of lines 26 and pump the water of the chambers 3 via the outlet channels 14 against the water pressure in the sea. Thus, the energy caused by this excess power, reduced by the component and system efficiency, a potential transformation of the amount of water in the chambers 2 through the created drop height potential 6 between the water surfaces 23 and 24 in the memory. the volume of the pumped out water in the chamber 3 is replaced by the ambient air flowing through the ventilation duct 5. How to make the distance of the power plant 1 to the support and guide pillars 20 and the damping devices visible, is the entire power plant 1 in floating state because the amount of water in the Ka has not yet taken its nominal volume mmer second For this purpose, the controllable openings 8 by the pusher 9 in the direction set to "on", whereby the inflow of sea water takes place.

In principle, sample is located below the two chambers 2, 3 of the control chamber 15 of the power plant 1, in the power lines 16 and 17 of the electric motors 13 and generators 1 1, together with the control means 18 of the connecting channels 4 for the control 25 objective with the nichtdarge- presented inlet and outlet lines 26 and 27 are interconnected.

FIG. 4 shows the memory of the power plant 1, by the filled volume of the chamber 3 close to its "idle" state. The water turbine 10 can probably over an existing drop height 6 the generator 1 1 open valve 7, a certain amount of time with lower specific driving performance. dignity may increase the water from the chambers to the venting tubing 5, the drop height would move 6 to the value 0, but this would not take place in the real mode of operation by tolerances of the lower case height 6.

Due to the large mass of water in the chambers 2 and 3 provides a high average density of the total power plant 1, which is above the density of the seawater. Due to the thereby caused Sinkneigung of the power plant 1, the supports and guides 20, 21 are via respective pillar, are anchored in the seabed, active as a support for the power plant 1 for the height stabilization.

An almost full memory state, which is seen from the largely empty lower chambers 3, FIG. 5. The upper chambers 2 are also almost completely filled for a high falling height 6 in the example shown. Nevertheless, the average density of the entire power plant is still below the sea water density. The depth of the power plant 1 was controlled here by the inner total amount of water so that the location of the power plant 1 still set with a slight spacing for supporting the Abstützung- and damping devices 20, 21 in the floating condition often optimal. For delivering electric current, the valves are opened 7 before the water turbine, whereby the drive of the generators is made possible to produce electricity.

In the case that the inner mass of water, and the total weight of the pumped storage power plant 1 to a constant value by the same supply as well as the same flow of water during the "filling phase" of the memory is regulated, there is the possibly desired solid mapping the average density of the entire power plant to the density of the seawater. so it can be brought about in the desired manner on the control 25 of the inner volume of water with the respective necessary components of the swimming pools as well as the Sinkzustand of the pumped-storage power plant.

Generally, the volume values ​​of the leegepumpten chambers 3 are mainly used for the sizing to be stored target energy amount and the volume values ​​of the chambers 2 for the comparison of the operations of the entire pumping storage power plant 1 on a floating, optionally floating or falling state through a stützungs- high or low power demand for the waste and damping devices 20, 21, which must be received in corresponding pillars, and the sea floor foundations.

At least parts of the walls 19 of the chambers 2, 3 and 15, or

Pumped storage power plant modules 1 are preferably made of steel and moldable concrete on land, whereby manufacturing method of the conventional shipyards will play a not insignificant role. reference numeral
