Method to produce electric energy

FIELD: electricity.

SUBSTANCE: method to produce electric energy includes installation of two non-polarised electrodes in a zone of continuous water flow in a sea or river at a distance from each other and from the bottom. Current-collecting lines are connected to the electrodes to transfer a difference of values of natural electric field potentials between the electrodes to a coastal station of electric energy collection. At the station they sum up the difference of potentials from all such pairs of electrodes, convert into AC and send to consumers.

EFFECT: provision of the possibility to produce electric energy by simple means.

 

The invention relates to hydropower, particularly to a method of use of water resources for generating electrical energy, and can be used to produce electrical energy suitable for supplying small villages, stations, observatories and other remote objects.

The known method (see EN 2431758 C1, 20.10.2011) electricity generation and device for its implementation, which consists in the use of water resources in lowland rivers to generate electric energy by the motion of the magnets relative to the coils of conductive drive under the influence applied to the conduit of the flow of water.

However, the method requires the use of a special conduit, special technical equipment and maintenance, which complicates its use.

Also known is a method of obtaining electrical energy, characterized by the movement of charged particles moving under the influence of electric external forces through the magnetic circuit and the electrical energy is removed by winding wound on a magnetic core (see EN 2009105427 A, 27.08.2010).

However, for the application of the method requires a special device, which, as in the first case, complicate the application of the method.

The present invention is the ability to produce electric power, simple and means.

This object is achieved in that in the method of generating electrical energy, including installation in the constant flow of water in the sea or the river two polarizadas electrodes at a distance of 50-300 m from each other and 2-10 m from the bottom, to which are connected the collector line for transmission to the difference of the values of the natural potentials of the electric field between the electrodes on the coastal collection station electric energy, which summarized the potential difference from all such pairs of electrodes is converted into alternating current and is passed on to consumers.

According to the law of electromagnetic induction in a moving stream of water there is an electric field, owes its origin to the earth's magnetic field. This "potential induction obeys the Poisson equation: Δ2F=N×V, where F is the electric potential; H - magnetic field intensity vector; V is the velocity of the stream.

We are interested in the horizontal component of the electrodynamic field. This component also depends on the thickness of the moving layer of water (h (2 to 10 m). The final formula will look like:

FXhVmHz

where: F is the electric floor is;

h - thickness of the moving layer of water;

Vm - flow rate;

Hz is the vertical component of the magnetic field intensity vector.

The amount of tension electrodynamic electric field will be reduced in the presence of sediments low resistance, while the bedrock high resistance located near the bottom of the can, on the contrary, increase its value.

System for generating electrical energy must be installed in a moving stream of water in the layer with the greatest velocity.

Then, in simplified form, the formula for the tension (Ed) will look like this:

Ed=Hz×L×Vm where: Hz - tension vertical component of the magnetic field, L is a linear plot, which is calculated Ed, Vm is the average velocity.

To obtain the maximum electric power should be placed collector lines (pair polarizadas electrodes) in the straight sections of the water flow in the river or on the site of the permanent sea currents.

If there are multiple identical collector lines tension electrodynamic fields will increase in proportion to their number.

To obtain industrial values should gain collector "bus" of several thousand lines. The line should be a cable core of conductive Mat is the Rial, prisoner in isolation. Ordinary household conductive wires have a core of copper, aluminum, iron or mixed fibres. Thus the energy loss in such wires will be significant. The core is expediently made of modern materials with low electrical resistance.

This method of getting electrical energy is a simple, very cheap and absolutely safe for the environment.

Thus, we propose a method of generating electrical energy based on the occurrence of an electric current between the electrodes attached to the ends of the conductive cable, located in the zone of constant flow of water in the sea or the river, under the influence of earth's magnetic field; different environmental security, capacity increase of the received power, can be used in any area that has a reservoir with a constant flow of water.

Experimental observation method were carried out in the zone of permanent currents in the coastal zone of the Throat of the White sea, in the Eastern part of the Gulf of Finland and on the river Sister Leningrad region. Selected straight water, which at a distance of 5-10 meters from the bottom hung measuring line. Line, consisting of a conducting cable length of 50, 150 and 300 m, the ends were connected to depolarizing electrodes, consisting of ceramic cups, which were placed chlorinated lead rods embedded in a concentrated solution of calcium chloride, high viscosity which was provided by adding agar-agar or gelatin. The resulting difference values of the natural electric field between the electrodes was for the above lines of 0.6; 1.1 and 3,15 MB for sea conditions and 0.32; 0,94 and 2.25 mV - for the river. Doubling equal length lines was made only for the area of the Throat of the White sea. Line length was 150 m Multiple measurements of the potential of the EP showed a mean value of 1.93 MB. Obviously some decrease in value relative to the value of 1.1*2=2,2 mV is associated with the loss in the cables.

The way to obtain electrical energy, including installation in the constant flow of water in the sea or the river two polarizadas electrodes at a distance of 50-300 m from each other and 2-10 m from the bottom, to which are connected the collector line for transmission to the difference of the values of the natural potentials of the electric field between the electrodes on the coastal collection station electric energy, which summarized the potential difference from all such pairs of electrodes is converted into alternating current and is passed on to consumers.
