The technical FIELD
The invention relates to a system of power generation, which uses wind energy to rotate the guide, and applies a magnetic field to the rotating conductor to heat the conductor by induction to heat the heat transfer medium, and converts the heat of the heat conductive medium into electrical energy to generate electricity.
In recent years, systems for the generation of electricity using renewable energy such as wind and sunlight, attract attention due to the reduction of greenhouse gases.
For example, non-patent literature 1-3 describes technology related to generation using wind energy. Generation, wind power, wind turbine rotates with the wind to be powered electricity generator to generate electricity. In other words, it converts wind energy into rotational energy and retrieves it in the form of electricity. The generation system using wind energy, usually designed so that the pole has an upper section with gondola containing the attached wind turbine with horizontal axis wind turbine having a rotating shaft generally parallel to nab the making of the wind). The gondola contains a button in it, accelerating the transfer, which is faster and, thus, gives the speed of rotation of the shaft of the wind turbine, and an electric power generator is driven by the output power of the accelerating transmission. Overdrive increases the speed of the wind turbine to the speed of rotation of the generator power (for example, 1:100) and contains a built in her transmission.
Currently, to reduce the cost of electricity generation, there is a tendency to increase the size of the wind turbine (or generation system using wind energy), and in the practical use of introduced generation system, wind power, 5 MW wind turbine with a diameter of 120 m or more. Having such a large system generation using wind energy is large and heavy and, consequently, in many cases, for constructional reasons, is built in the sea.
Moreover, generation, wind power, provides a variable output power energy generation (or generates electricity in different quantities) as the wind changed, and, accordingly, the system of accumulation of electricity is also provided for the power generation system using wind energy to accumulate unstable (electricity) what s in the battery, to smooth power output.
On the other hand, for example, non-patent literature 4 describes a technology relating to the generation, use of solar thermal energy. Generation using solar thermal energy accumulates the heat of the sun, converts it into heat energy and uses thermal energy to generate steam to drive a turbine to operate an electricity generator to generate electricity. In other words, it converts solar energy into thermal energy and ejects it in the form of electricity. The generation system using solar thermal energy which is put into practical use, is in the form of a post, for example. This is the system that collects sunlight in a solar collector provided on the upper section of the column, and uses the heat to generate steam, which in turn is delivered to the turbine provided at the lower section of the pole to rotate a turbine to operate an electricity generator to generate electricity (see non-patent literature 4, Fig.3).
Generation using solar thermal energy also provides output power, changing with the weather, time and the like, and, accordingly, for the stable generation of electrogene the GII for generation system, using solar thermal energy is provided by heat accumulation system, is capable of accumulating heat in thermal battery and remove the heat required for the generation of electricity.

A BRIEF STATEMENT of the substance of the INVENTION
The system of generators is tion, using wind energy with a system of electric power accumulation, and the accumulation system of electricity required components such as a transformer and the like, to store energy in the battery, and thus, it causes a complication of the system and increase power losses. Moreover, the large size of the generation system using wind energy requires the battery pack high capacity corresponding to the number of generated electricity and, thus, increases the cost of the entire system.
On the other hand, the generation system using solar thermal energy, equipped with a thermal storage system, which is simpler system of generating electricity and heat accumulator besides cheaper batteries. However, while generation using wind energy can generate electricity at night, only if there is wind generation using solar thermal energy, can not generate electricity at night. Accordingly, the latter requires large-scale heat accumulator, in order to continue to supply electricity at night.
Moreover, when the generation system using wind energy, has faults, they often refer to the Troubleshooting accelerating the th transmission, more specifically, to the transmission. If the transmission has a defect, this defect can usually be corrected by replacing the transmission on the other. However, if the gondola is equipped with her on the top section of the pole, securing and removing the gearbox requires a large amount of time and effort. Of course, nowadays, there is a direct-drive type speed change, which does not require accelerating the transfer.
However, the system energy generation type direct drive system, in particular, uses an electric power generator with an increased number of poles (or multipole generator power), and if it be compared with a system of energy generation using accelerating the transfer, the first uses electricity generator and the increased size and weight. In particular, it is believed that the large size of the generation system, wind power, class 5 MW contains an electric power generator having a weight exceeding 300 t (300000 kg), and install it in the gondola is very difficult.
The present invention was made in view of the above circumstances, and one of its tasks is the provision of systems for the generation of electricity using wind energy, which is excellent in maintainability, and is able to reduce the size and weight of the nacelle provided on the upper section of the column.
N the standing system of power generation includes: wind turbine; the conductor rotating with the rotation of the wind turbine; a magnetic field generator generating a magnetic field intersecting a conductor; heat transfer medium receiving heat from the conductor rotating in a magnetic field and, thus, heating by induction; and unit electricity generator that converts heat transfer medium into electricity.
This system of power generation converts wind energy into rotational energy, and then into thermal energy, and retrieves it in the form of electricity and, thus, is non-traditional, innovative system of electricity generation. This system of power generation has the following effects: (1) it uses wind energy and, therefore, can generate electricity at night and, if it is supplied by thermal battery may have a heat accumulator smaller than can be generating system using solar thermal energy; (2) it uses the energy of rotation of the wind turbine to generate heat, and uses the heat to generate electricity, which eliminates the necessity of providing a system of accumulation of electricity; and (3) it can do without accelerating the transfer and, thus, free from fault, caused by the transmission.
Thus the m the rotational energy can be used to generate frictional heat. However, in this case, the component that generates the heat of friction, wear out with use, and, accordingly, the component should be changed periodically, which is a disadvantage from the point of view of maintainability. On the contrary, the present invention uses rotational energy to rotate the conductor generates heat by induction heating and, thus, is more profitable than the heat by friction, from the point of view of maintainability.
This system of power generation in one of the embodiments includes: a column, passing higher than the location of the unit power generation; and the gondola provided on the upper section of the post and provided with a wind turbine, a conductor and a magnetic field generator. Moreover, the present system of power generation in one of the embodiments includes: a container transfer medium located in the gondola and containing a heat transfer medium receiving the heat conductor; and a transport pipe for delivering the heat transfer medium in the container transfer medium unit of electricity generation.
Wind turbine attached to the gondola, provided on the upper section of the column, called the em to use wind energy from high wind speed is high in the sky. Moreover, the transport pipe which delivers the heat transfer medium in the unit of electric power generation, provided at the lower section of the column (or the base), for example, can eliminate the need to supply gondola unit electricity generation and makes it possible to provide the upper section of the column is reduced and lightweight gondola.
Moreover, the present system of power generation in the specific forms may include the following:
the form in which block the generation of electricity contains the turbine, rotating the heat transfer medium, and an electric power generator driven by the turbine;

DESCRIPTION of the PREFERRED embodiments of the INVENTION
The present invention in the embodiment will be described in further materials of the present application with reference to the drawings. Note that in the drawings, the same components are denoted by the same.
The first option exercise
Fig.1 depicts a system W of power generation, including wind turbine 10, the conductor 20, the container 30 transfer medium, the generator 40 of the magnetic field, the heat accumulator 50 and the block 60 electricity generation. Wind turbine 10 is attached to the nacelle 102 provided on the upper section of the pole 101 and the conductor 20, the container 30 transfer medium and the generator 40 of the magnetic field are located in the nacelle 102. In addition, the heat accumulator 50 and the block 60 electricity generation is provided in the building 103, located on lower part (or base) of the post 101. System W power generation is configured, as will be described in more detail below in the materials of this application.
Wind turbine 10 is composed of horizontal rotating shaft 15 and the three blades 11 attached to the rotating shaft 15 radially. For generation system using wind energy, with output power exceeding 5 MW, it has a diameter of 120 m or more and the rotation speed n is IMEMO 10-20 rpm
The conductor 20 is connected to the rotating shaft 15 and rotates with the rotation of the wind turbine 10. The conductor 20 is made of a material heated by induction, since an eddy current is generated when the material is rotated in a magnetic field. The conductor 20 may, for example, be made of such metal as aluminum, copper, iron and the like. If the conductor 20 is made of aluminum, its weight can be reduced. If the conductor 20 is made of iron or similar magnetic material, it allows you to increase the magnetic flux density and, hence, to increase the eddy current (or heating energy). Accordingly, the conductor can have a plot, equipped with a magnetic material, and, for example, a columnar (cylindrical) conductor (e.g., aluminum) may have a center, equipped with a magnetic material (e.g. iron).
Moreover, the conductor 20 may be circular columnar, circular cylindrical, polygonal columnar, polygonal, cylindrical or the like, having various forms.
The container 30 transfer medium contains embedded in it, the conductor 20, and contains located therein a heat transfer medium to receive heat from the heated conductor 20. A heat transfer medium may be a liquid, such as water, oil, melt the military salt, for example. In the materials of the present application will be described an example of a heat transfer medium in the form of water.
The generator 40 of the magnetic field has a structure having a pair of magnets 41 and 42, located opposite each other located between the conductor 20. In the materials of the present application, the magnets 41 and 42 are implemented as permanent magnets and generate a magnetic field of constant current, allowing the magnetic flux leaking from the magnet to the magnet 41 42 (see Fig.3(A)). The generator 40 of the magnetic field may be a permanent magnet and may instead use a coil with a normal conductive or superconductive coil, or something like that, excited to generate a magnetic field.
In the system W power generation generator 40 of the magnetic field is controlled to generate a magnetic field, and the conductor 20 is rotated therein and, thus, is heated by induction, and the heat conductor is transferred to water (or heat transfer medium in the container 30 transfer medium to cause a high temperature and steam under high pressure. The generated steam is delivered to the heat from the battery 50 through the transport pipe 51, which connects the container 30 transfer medium and the heat accumulator 50.
Heat accumulator 50 takes couples through the transport pipe 51 and accumulates it is EPLO, as well as supplying unit 60 electricity generation steam required for the generation of electricity.
Block 60 electricity generation has a structure formed by the combination of a steam turbine generator 61 and 62 of the electricity, and uses the steam supplied from the heat accumulator 50 to rotate a steam turbine 61, and thus actuates the generator 62 energy to generate electricity.
Heat accumulator 50 and the block 60 electricity generation can use technology generation using solar thermal energy. Heat accumulator 50, for example, may be a steam accumulator, accumulating steam in the form of water under pressure, or a thermal battery type dry heat using molten salt, oil and the like, or heat accumulator-type latent heat using phase changes molten salt having the melting point. System heat accumulation type latent heat accumulating heat in accordance with the temperature of the phase change heat storage substance, and thus has a narrower temperature range heat accumulation and a higher density build-up of heat than the battery type dry heat. Moreover, the heat accumulator 50 may be equipped with a heat exchanger, and the heat accumulated in the heat accumulator 5, can be used to use a heat exchanger to generate steam required for the generation of electricity.
The steam delivered to the heat accumulator 50, accumulates heat in the heat accumulator 50 or rotates the turbine 61, then cooled condenser 71 pair, and, thus, is condensed into water. Subsequently, water is delivered to the pump 72, and then, in turn, under high pressure is delivered through the pipe 73 of the water in the container 30 transfer medium and thus circulates.
Now will be discussed the specification of this system of power generation. In materials of this application it is assumed the system is generating electricity, providing output power exceeding 5 MW. Specifically made a trial calculation of the size of the conductor that you want to generate thermal energy 7.2 MW, when the conductor is rotated with a speed of 15 rpm
NPL 5 reveals that a constant current is passed through the superconducting coil to generate a magnetic field, and rotates conducts electricity the disc, and thus heated by induction. This literature describes the specification of the induction heating device which heats a circular columnar aluminum disc, as follows: input power: 360 sq is, rotation speed: 240-600 rpm, the size of discs: diameter of 178 mm, length 690 mm
Induction also provides power P, represented by the following expression (see Handbook of electrical engineering (published by the Institute of electrical engineers of Japan, publication date: February 28, 1988 (first edition)), page 1739):
P = 2.5 fH2LμrAQ10-8(in the CGS system of units).
In this expression, f is the frequency (1/s) and can be obtained from the rotation speed of the conductor. H represents the magnetic field strength (e) and in the materials of this application is set constant. L is the axial length of the conductor (in cm), A is the cross-section (in cm2), and L×A is the volume of the conductor. μrrepresents the relative magnetic permeability of the conductor, and Q is a correction factor dependent on the geometry of the conductor. The value of Q is also fixed to represent Explorer, geometrically similar to the above-mentioned circular columnar block. From the expression (1) can be seen that the power P (W) is proportional to the frequency f and the volume (length L × area (A).
When the system g is the generation of electricity compared with the above-mentioned induction heating device, system of electric power generation has speed, approximately 1/20 the speed of the induction heating device, and, on the other hand, generates heat, about 20 times the input power of the electric power to the induction heating device. Accordingly, the proposed generation system electricity needs a conductor having about 400 times greater volume, as estimated.
As a result of the trial calculation, if the conductor is a circular columnar aluminum disc, for example, he will be the amount equivalent to 1320 mm in diameter × 5110 mm in length, the volume is about 7 m3and weight of approximately 21 tons (21000 kg, converted with density 3 g/cm3). In addition, together with other equipment located in the gondola, it is expected that the gondola will have a weight of about 50 tons For generation system using wind energy, providing output power 5 MW direct-drive type includes a nacelle having a weight exceeding 300 so you Can see that the present system of power generation may have equivalent or better abilities as well as significantly reduce the weight of the gondola.
First rough edit
The first version of the implementation has been described with reference to the example of the magnetic field generator in the form of a permanent magnet is. Alternatively, you may use a coil with a normal conductive or superconductive coil to be supplied with power and thus be excited to generate a magnetic field. An example of a magnetic field generator, which uses a superconducting coil as a means for generating a magnetic field, will be described with reference to Fig.2.
With reference to Fig.2, the generator 40 of the magnetic field contains a superconducting coils 45 and 46 located opposite each other with the conductor 20, which is located between them. Superconducting coil 45 (46) is located in the cooling container 80, attached to the refrigeration machine 81 the cooling head 82 and, thus, is cooled by condensation. The superconducting coil, compared to the coil with normal conductivity, makes it possible to generate a stronger magnetic field and, thus, can help to achieve smaller size and weight. Moreover, when using a superconducting coil, without costing an iron core, it is possible to eliminate magnetic saturation and, since the iron core is absent, can be achieved more weight loss.
In addition, when using a superconducting coil, the coolant (liquid nitrogen, for example) may be injected into the cooling container and superconducting cat is ka can be immersed in the cooling liquid, while the coolant can circulate and, thus, to cool the refrigerating machine. In this case, the circulation mechanism, such as a pump which pumps the coolant, can be placed in the gondola or can be located in the building, located on the lower section of the column.
The second exemplary variant of the incarnation
The first version of the implementation was described using the example of a generator of a magnetic field, containing two magnets facing each other. In the alternative, can be used three or more magnet. For example, the set of magnets located along the direction of the circumference of the conductor with magnetic poles arranged alternately. For example, as shown in Fig.3(B), if you use four magnets 41 to 44, a magnetic field is generated to cause the leakage of magnetic flux from the magnets 41 and 43 to the magnets 42 and 44.
The third exemplary variant of the incarnation
The first version of the implementation was described using an example that includes a magnetic field generator generating a magnetic field, DC, providing a magnetic field, which does not change with time. Alternatively, you can use a set of coils to generate a rotating magnetic field. For example, multiple coils can be located along the upravleniya around the circumference of the conductor, so the coil was energized sequentially to generate a rotating magnetic field along the direction of the circumference of the conductor. More specifically, the pair of coils may be located along the direction of the circumference of the conductor radially opposite each other, and three such pairs may be located along the direction of the circumference of the conductor at an equal distance. Note that setting the direction of the rotating magnetic field is opposite to the direction in which it rotates Explorer, may increase imaginary rotation speed of the conductor and, therefore, the generated heat energy. When generating a rotating magnetic field, each pair of coils may be excited by a current corresponding to the phase 3-phase alternating current, for example.
The fourth exemplary variant of the incarnation
The first version of the implementation was described using an example that uses a heat transfer medium in the form of water. Alternatively, the liquid metal having a higher thermal conductivity than water, can be used as a transfer medium. This liquid metal is liquid sodium, for example. If the transfer medium is used the liquid metal, then, for example, the liquid metal can be used as a primary transfer medium, taking the heat from her conductor, and the warmth of the liquid metal fed through the transport pipe, can be used to heat secondary heat transfer medium (or water) through a heat exchanger to generate steam.
Note that the present invention is not limited to the above variants of the implementation and can appropriately be changed in limits that do not depart from the essence of the present invention. For example, a conductor, a heat transfer medium and the like may be changed appropriately, and the magnetic field generator may be implemented with a coil with normal conductivity.
This system of power generation suitable for use in the generation of electricity using wind energy.
