Description

Artificial intelligence wind power generation system and the method of generating power therefrom

[0001] The present invention relates to an artificial intelligence wind power generation system and a method of generating power, which is configured to generate wind power consistently and continuously for an artificial structure that moves while driving an electric motor to generate wind power, and to generate power for self-generation by a generator that generates power based on the wind power, and furthermore, to improve the quality of use by producing and supplying power at a frequency of 60 Hz per second through a cyclo converter to which digital control by artificial intelligence is applied to the electric motor.

[0002] Generally, large wind turbines have the disadvantage of having long periods of no wind, and even when wind blows, the wind speed is lower than what rotates the turbine. Furthermore, the mismatch between the wind direction and the blade direction results in a significantly low operating rate, leading to poor energy efficiency and profitability, as well as high construction costs.

[0003] Large wind turbines cannot generate power simply because the blades rotate due to wind. In other words, power generation cannot occur unless a certain wind speed is reached (starting phase), and power generation is only possible once the starting wind speed is exceeded. However, if the wind speed reaches a certain limit, power generation exceeding the rated output is not possible. At this point, the turbine is designed to stop operation to prevent damage to the generator structure when the terminal wind speed is reached, so the limit wind speed is typically 25 m / s.

[0004] In addition, small and medium-sized wind turbines have a problem in that power generation drops significantly because the rotation of the generator is irregular due to the inconsistent wind speed inherent in natural wind.

[0005] Meanwhile, the maximum power production condition requires achieving a power frequency of 60 Hz per second, which is a property of the generator and supplies power to the user, but there was a problem that this was virtually impossible with natural wind. As one of such wind power generation systems, Korean Patent Publication No. 10-1183624 (Title: Wind turbine equipped with multiple generators: Registered September 11, 2012) describes a wind turbine equipped with multiple generators comprising: a support section; a cylindrical body installed at the top of the support section so as to be rotatable in the vertical and horizontal directions, wherein the cylindrical body is configured such that wind can flow through the interior and is composed of a plurality of small-diameter sections with relatively small diameters, each having at least one generator mounted from a large-diameter section at one end; and at least two generators having blades and nacelles along the centerline of the cylindrical body in the small-diameter sections of the cylindrical body. In this wind turbine, the power produced by the generators is charged into a common battery, the cylindrical body is equipped with a vertical tail fin and a horizontal tail fin at the rear end, a plurality of drainage holes are formed in the inner bottom portion of the cylindrical body, and a door that can be opened and closed for maintenance is installed on the side of the cylindrical body at the location where each generator is installed. A wind turbine is listed.

[0006] And in the publication of Korean Patent Registration No. 10-0966031 (Title: Building-type wind power generation system: Registered June 16, 2010), there are first and second housings accommodating first and second generators; a third housing accommodating the first and second housings; and a vertical shaft each coupled and supported by an axial bearing between the inner central leading end and the trailing end of the third housing; A multi-stage large-scale wind turbine is described in which wheels mounted on the lower part of the wind turbine are supported and operated on each rail. In order to maximize wind power, a plurality of cylindrical supports are located at the outer ends of a plurality of supports that are smaller in height than their diameter from a vertical axis. A plurality of long blades are attached to the outer side of the cylindrical supports, each having an L-shaped cross section and having different lengths on both sides. Each blade's folded surface is attached to the outer side of the cylindrical supports such that the recessed surface of the blade faces the outer direction of the cylindrical supports. A rotor is arranged adjacent to the blade end having a short length on the rear side of the long blade. A wind power generation system is described in which three rotors are combined by four mounting shaft bearings within three separate, independent housings on a single vertical axis.

[0007] In addition, Korean Patent Registration No. 10-1325597 (Title: Tunnel-type wind power generation device: Registered on Oct. 30, 2013) describes an air tunnel comprising: a first straight tunnel; a second straight tunnel arranged parallel to the first straight tunnel with a space between them; a connecting tunnel connecting one end of the first and second straight tunnels; and an extension tunnel that communicates with the suction motor and extends from the other end of the second straight tunnel, wherein an open end is installed to maintain a certain distance from the other open end of the first straight tunnel, and the open ends of the first straight tunnel and the extension tunnel serve as an air inlet and an air outlet, respectively. A wind power generation device is described comprising: a turbine generation unit comprising a rotating shaft that is movable by forming a through hole in the inner wall of the first and second straight tunnels and installing a bearing in the through hole, and left and right turbines rotatably installed at both ends of the rotating shaft extending into the interior of the first and second straight tunnels, wherein the rotating shaft and turbines are arranged in multiple numbers at regular intervals along the longitudinal direction of the first and second straight tunnels; and a generator and a battery electrically connected to the turbine generation unit.

[0008] In addition, Korean Patent Publication No. 10-2009-0110586 (Title: Mutually Reverse Rotating Wind Power Generation System Installed in Ventilation Tunnel: Published on October 22, 2009) describes a wind power generation system configured such that a front wing and a rear wing are combined at the front or rear of a generator body and rotate in opposite directions relative to the same wind direction, and a wind power generator is provided inside the generator body, which is connected to the front wing and the rear wing respectively, and generates power as a coil and a magnet rotate in opposite directions, and the plurality of wind power generators are installed continuously inside a ventilation tunnel for air intake and outflow of a subway or large building, and the power generated by the operation of the wind power generators by the wind passing through the ventilation tunnel is charged into a separate rechargeable battery.

[0009] Conventional wind power generation systems have a significantly low operating rate of generators, resulting in poor profitability and high construction costs. In particular, there is a problem in that power generation cannot be performed unless a certain wind speed is reached (starting phase), and power can only be generated when the starting wind speed is exceeded. Furthermore, due to the characteristics of natural wind, the wind speed is inconsistent, causing the rotation of the generator to be irregular and the amount of power generated to drop significantly. This makes it virtually impossible to achieve a power frequency of 60 Hz per second to supply power to users with natural wind.

[0010] The present invention is proposed to solve the problems of the past, and the objective of the present invention is to provide an artificial intelligence wind power generation system and a method of generating power that is configured to generate wind power consistently and continuously for an artificial structure moving while generating wind power through the driving of an electric motor, and to generate power for self-generation by a generator based on the wind power, and to improve the quality of use by producing and supplying power at a frequency of 60 Hz per second through a cyclo converter to which digital control by artificial intelligence is applied to the electric motor.

[0011] Another objective of the present invention is to provide an artificial intelligence wind power generation system and a method for generating power therefrom, which is configured to improve the decrease in power production rate caused by irregular natural wind and to produce and supply the maximum power possessed by the wind power generator (DC, AC generator) to the user. This is achieved by solving the problem of conventional small and medium-sized wind power generators in which power is produced by generating a harmonic (not a sinusoidal) waveform, even though the rotational speed of the blades is not constant and the frequency (f) waveform of the wind power generator should normally be formed as a regular waveform.

[0012] In addition, another objective of the present invention is to provide an artificial intelligence wind power generation system and a method for generating power therefrom, configured to solve the problems of conventional wind power generators, which have disadvantages such as: when the rotational speed of the rotor, which is the field of a small and medium-sized wind power generator (AC generator), is irregular, a phase difference (when there is a slight time difference between voltage and current) which is the armature reaction of the wind power generator occurs, causing the magnetic flux generated in the field to decrease and reactive power to be generated; and when the time at which voltage and current are generated coincides, a voltage (A) greater than that when the time at which voltage and current are generated flows through the armature winding, which is the stator of the AC generator, the power factor is lowered and power production is reduced, heat is generated within the generator, and the lifespan of the armature winding is affected.

[0013] An artificial intelligence wind power generation system according to the present invention for achieving the above-mentioned objectives of the present invention comprises: an artificial wind structure having a moving space formed therein for wind pressure to move; a generating motor configured to generate artificial wind by being positioned at an inlet where air pressure is introduced in the moving space of the artificial wind structure; a blade rotation shaft coupled with a generating blade configured to form rotational pressure by the moving wind pressure provided in the moving space of the artificial wind structure; a generator configured to generate electrical energy by receiving rotational force while connected to the blade rotation shaft; a digital controller configured to control the driving of the generating motor so as to maintain wind pressure that forms power tailored to a frequency of 60 Hz per second for the generator in the moving space; and a cyclo converter configured to precisely convert and supply alternating current with a frequency of 60 Hz per second through power formed at a frequency of 60 Hz per second, which is electrically connected to the generator.

[0014] It further includes a wind speed sensor configured to detect the intensity of wind pressure supplied to the generator in the above moving space and to transmit the detected wind speed detection data to the digital controller.

[0015] The digital controller is characterized by controlling the rotational speed of the generating motor to form a wind speed that generates power at a frequency of 60 Hz per second, calculated in advance by performing calculations based on the wind speed detection data.

[0016]

[0017] It further includes a rotational speed measuring sensor configured to be provided in a rotational shaft bushing or bearing that fixes the wing rotational shaft so as to be rotatable inside the artificial wind structure, and to detect the rotational speed of the wing rotational shaft and transmit the detected rotational speed detection data to the digital controller.

[0018] The digital controller is characterized by controlling the rotational speed of the generating motor to form a wind speed that is adjusted to form a rotational speed of the blade rotation shaft that generates power at a frequency of 60 Hz per second, calculated in advance based on the rotational speed detection data.

[0019]

[0020] It further includes a frequency measuring sensor electrically connected to the generator and configured to detect the frequency per second generated by the generator and transmit the detected frequency detection data to the digital controller.

[0021] The digital controller is characterized by being configured to drive and control the rotational speed of the generating motor to form a wind speed that is adjusted to form a rotational speed of the blade rotation shaft that generates power at a frequency of 60 Hz per second, calculated in advance based on the frequency detection data.

[0022]

[0023] The power transmission gear member further comprises a movable bevel gear axially coupled to the blade rotation shaft, and a driven bevel gear provided on a driven gear shaft connected to the rotation shaft of the generator and gear-coupled with the movable bevel gear.

[0024] It is characterized by further including an induction means provided between the generating motor and the generating blade, configured to induce wind pressure generated from the generating motor in the direction of the generating blade.

[0025]

[0026] The artificial intelligence wind power generation method according to the present invention for achieving the purpose of the present invention is characterized in that it generates artificial wind in a moving space where wind pressure moves, and is configured to convert wind pressure into electrical energy to generate power, wherein the wind speed is formed through automatic control applied with artificial intelligence so as to maintain wind pressure that is matched to a frequency of 60 Hz per second with respect to the electrical energy formed in the moving space.

[0027] The artificial intelligence wind power generation system and the power generation method according to the present invention, implemented in this manner, have the effect of commercializing the problem of electrical energy, which is an essential condition for human life, by implementing it not only through large-scale generators but also through small and medium-sized generators.

[0028] Furthermore, it not only enables the replacement of thermal power plants that mass-produce carbon monoxide and carbon dioxide, the main culprits of global warming, but also has the effect of realizing an eco-friendly power generation system by converting large-scale power plant systems into small-scale self-generation systems utilizing wind power.

[0029] In addition, power generation facilities can be easily installed even in remote areas requiring electrical energy, and can be readily applied to transportation devices such as automobiles and ships to generate electrical energy for transport, thereby having the effect of promoting innovation in the energy market.

[0035] FIG. 6 is a schematic example diagram showing the control relationship of an artificial intelligence wind power generation system according to the present embodiment.

[0036] Hereinafter, with reference to the attached drawings, an artificial intelligence wind power generation system and a power generation method according to a preferred embodiment of the present invention will be described in detail as follows.

[0037] FIGS. 1 to 6 are drawings showing an artificial intelligence wind power generation system (1) according to an embodiment of the present invention.

[0038] The artificial wind power generation system (1) according to the present embodiment comprises: an artificial wind structure (100) having a moving space formed for wind pressure to move; a wing rotation shaft (2) coupled with a power generation wing (21) configured to form rotational pressure by the wind pressure moving in the moving space of the artificial wind structure (100); a rotation shaft bushing or bearing (3) that fixes the wing rotation shaft (2) so as to be rotatable inside the artificial wind structure (100); and a generator (4) configured to receive rotational force and form electrical energy while connected to the wing rotation shaft (2).

[0039] That is, the wind pressure energy moving in the moving space provided inside the artificial wind structure (100) is received by the power generation wing (21), converted into rotational energy, and rotates while the wing rotation axis (2) rotates simultaneously, and the generated rotational energy is received by the generator (4) to form electrical energy.

[0040] The artificial wind structure (100) may have a 'tube' shape in which both ends are penetrated, and the inlet and outlet are provided at each end, respectively, and the movement space provided between them is formed as a straight line in one direction. The configuration and structure of the artificial wind structure (100) can be appropriately applied according to the user's choice.

[0041] In the above, the artificial wind structure (100) may be formed in a 'ring' shape in which the internal moving space circulates wind pressure energy, and an inlet for wind pressure to flow in from the outside may be formed on a part thereof. The configuration and structure of the artificial wind structure (100) can be appropriately applied according to the user's choice.

[0042] The artificial wind structure (100) may be composed of a pair of straight tubes (110) arranged parallel to each other so that wind pressure moves linearly, and a pair of curved tubes (120) in the shape of a semicircular arc connecting both ends of the straight tubes (110).

[0043] The power generation blades (21) may be arranged in each of the straight tubes (110) to form rotational motion for power generation. The configuration and structure of the straight tubes (110) may be appropriately applied according to the user's choice.

[0044] The above-mentioned power generation blade (21) is configured to generate rotational force by converting wind pressure energy moving in the movement space of the above-mentioned artificial wind structure (100) into rotational energy, while simultaneously reducing wind pressure. The structure of the above-mentioned power generation blade (21) can be appropriately applied according to the user's choice.

[0045] The generator (4) receives rotational force generated from the generator blade (21) via the blade rotation shaft (2) and converts it into electrical energy to generate power. The configuration and structure of the generator (4) can be appropriately applied according to the user's choice.

[0046] The artificial intelligence wind power generation system (1) according to this embodiment further includes: a generating motor (5) configured to generate artificial wind by being placed at an inlet where air pressure is introduced in the moving space of the artificial wind structure (100); a digital controller (6) configured to control the driving of the generating motor (5) so as to maintain wind pressure that forms power at a frequency of 60 Hz per second for the generator (4) in the moving space; and a cyclo converter (7) configured to supply power at a frequency of 60 Hz per second, which is electrically connected to the generator (4), by precisely converting it into an alternating current at a frequency of 60 Hz per second through a direct current.

[0047] In other words, the cyclo converter (7) converts the AC voltage output from the generator into DC voltage and then converts it into AC voltage of the required frequency. Here, the required frequency refers to a frequency that is precisely converted at 60 Hz per second.

[0048] The generated motor is controlled and driven through artificial intelligence-type control of a digital controller for the wind pressure formed in the movement space of the above artificial wind structure (100), and power of 60 Hz per second is supplied to the cyclo converter.

[0049] Accordingly, as the wind pressure from the external natural wind flowing into the moving space through the above entrance does not have a constant intensity, the frequency of the electrical energy generated in the generator (4) is formed as a high-frequency irregular wave, and the problem of reduced power production rate occurs. Therefore, the generating motor (5) is controlled and driven to assist the wind pressure applied to the generator blade (21) to form artificial wind, so that the frequency of the electrical energy generated in the generator (4) is formed as a regular wave in the form of a sine wave.

[0050] Therefore, the power generation rate is reduced due to irregular natural winds, and the maximum power that the wind turbine (DC, AC generator) (4) has is produced and supplied to the user.

[0051] [Application Example 1]

[0052] The rated current of the generating motor (50) is explained while the artificial wind structure (100) is formed in a circular shape of Φ2050 (mm).

[0053] The motor of the above-mentioned generating motor (5) has a rated output of 400[W], and the actual rated current to be used is 2.5[A] x 60 seconds x 60 minutes (power consumption per hour: 9[kW]) at 3000[rpm], which is a value capable of rotating the blades of the above-mentioned generating motor (5) 50 times per second.

[0054] However, in reality, the above-mentioned generating motor (5) cannot rotate 50 turns due to the large structure of the blades.

[0055] Accordingly, if a reduction gear is configured in a 10:1 ratio to the motor of the generating motor (5), a motor can be configured such that when the motor of the generating motor (5) has a rotational speed of 3000 [rpm] per second, the blade rotates 5 times at a maximum rotational speed.

[0056] The maximum rotational speed of the selected generating motor (5) is 6000 rpm, with a capacity of 400 W. That is, the rotation of the blades of the generating motor (5) can be increased by 50 turns.

[0057] If the specifications of the artificial wind structure (100) are reduced or enlarged, the motor capacity of the generating motor (5) can also be changed.

[0058] ① Rated output 750[W], rated current 4.4[A], artificial wind structure (100) Φ 3000(mm) or more

[0059] ② Rated output 600[W], rated current 4.2[A], artificial wind structure (100) Φ 2200(mm) ~ Φ2900(mm)

[0060] ③ Rated output 400[W], rated current 2.5[A], artificial wind structure (100)Φ 1000(mm) ~ Φ2100(mm)

[0061] ④ Rated output 200[W], 150[W], rated current 1.6[A], artificial wind structure (100) Φ600(mm) ~ Φ900(mm)

[0062] ⑤ Rated output 100[W], rated current 0.85[A], artificial wind structure (100) Φ300(mm) ~ Φ300(mm)

[0063] ⑥ Rated output 50[W], Rated current 0.5[A]

[0064]

[0065] [Application Example 2]

[0066] The selection of the capacity of the generator (4) is explained in the state where the above artificial wind structure (100) is formed in a circular shape (circular form) of Φ2050 [㎜].

[0067] The amount of wind power generated (P) by the generator (4) above is determined according to the following formula.

[0068] P=½ρAV³

[0069] P: Wind turbine output or power (W)

[0070] ρ : Air density 1.225 [kg / m³]

[0071] A : Rotation area of ​​the generator blade (21) [㎡]

[0072] V : Wind speed [m / s]

[0073] [Source] Ministry of Trade, Industry and Energy, Korea Energy Agency, New and Renewable Energy White Paper (2020)

[0074]

[0075] In addition, the artificial intelligence wind power generation system (1) according to this embodiment can suitably apply Betz's Law (the limit of efficiency when using wind as energy is 59.36%).

[0076]

[0077] Typically, when applying the power generation efficiency of a wind turbine, natural wind has various factors hindering power generation, so the efficiency is applied at 15 to 50 percent, but artificial wind that is artificially formed allows the generator (4) to operate continuously, and if only mechanical hindering factors are applied, the efficiency can be applied at 70 percent.

[0078]

[0079] To calculate the rotational area of ​​the above-mentioned power generation blade (21), the area per power generation blade (21) must be multiplied by the rotational area of ​​the power generation blade (21) and multiplied by the number of power generation blades (21) installed.

[0080] The rotation area (RA) of the power generation blade (21) according to the size, radius of rotation, and number of the power generation blade (21) can be formed as follows.

[0081] In the case where the size of the above-mentioned power generation blade (21) is 300 [mm] x 1000 [mm] = 0.3 [㎡], the radius of rotation of the above-mentioned power generation blade (21) is Φ2000 [mm] x radius 1000 [mm] x 3.14 = 3.14 [㎡], and the number of above-mentioned power generation blades (21) is 3, RA = 0.3 x 3.14 x 3 = 2.85 [㎡].

[0082] When the above artificial wind structure (100) is Φ2000[mm], the capacity selection of the generator (4) can be expressed by a calculation formula.

[0083] P=½ρAV³

[0084] V: When the wind speed is 15 [m / s], P [W] = 2 ÷ kg / m³ x 2.85 m² x 45 [m / s] = 78.75 [W], and applying Betz's Law of 59.39 [%] gives 78.75 [W] x 0.59 = 46.47 [W], and applying a power generation efficiency of 70 [%] gives 46.47 [W] x 0.7 = 32.53 [W].

[0085] In the above calculation formula, the wind power of the generator (4) for one hour can be selected as 32.53[W] x 60 seconds x 60 minutes = 117.1[kW].

[0086] The power consumption of the above-mentioned generating motor (5) per hour is 9 [kW], and the power generation capacity of the above-mentioned generator (4) per hour is calculated to be 117.7 [kW].

[0087] In the power generation configuration of the above generator (4), if the number of power generation blades (21) is added to the blade rotation axis (2), the power generation amount increases by the number of added power generation blades (21).

[0088] In addition, if the diameter of the artificial wind structure (100) is doubled, the length of the power generation blade (21) is doubled, and the capacity of the generator (4) is also doubled, so the power generation capacity of the generator (4) is increased.

[0089] In addition, if the wind speed in the above moving space is doubled, the capacity of the generator (4) can be increased eightfold.

[0090] Natural wind spreads out widely in all directions and drops in a short distance when subjected to pressure, but artificial wind generated by the generating motor (5) can maintain a wind speed that advances the pressure by at least 5m inside the artificial wind structure (100), unlike natural wind.

[0091] In this embodiment, digital control based on artificial intelligence by a digital controller (6) is applied to the generating motor (5) to produce and supply power with a frequency of 60 Hz per second, thereby improving the quality of use.

[0092] Typically, the power used in daily life must have a frequency of 60 Hz per second. This frequency of 60 Hz per second is the frequency per second of the mechanical configuration of the generator (4), and the frequency per second of the mechanical configuration can be varied, such as 50 Hz or 80 Hz.

[0093] The frequency of 60 Hz per second should be understood simply as a reference value for the power production frequency of the mechanical configuration of the generator (4).

[0094] Since the above generator (4) is configured with a mechanical structure of an armature as a stator and a field (electromagnet or permanent magnet) as a rotor to produce a frequency of 60 Hz per second, the above blade rotation shaft (2) must rotate at a constant rate to match the frequency of 60 Hz per second so that the above generator (4) can produce the best power.

[0095]

[0096] Meanwhile, in a DC generator, when the field, which is the stator, generates magnetic flux [Φ] (magnetic field) from the N pole to the S pole, and the armature, which is the rotor, rotates and cuts off the magnetic flux [Φ] (magnetic field), an electromotive force [E] is generated. This electromotive force [E] is a current generated in the DC generator, but an alternating current is generated.

[0097] The generated alternating current is converted into a single-phase (two-phase) direct current through brushes by a commutator equipped on the generator's rotating shaft and stored in an energy storage device (ESS).

[0098] When using the stored DC electricity, it is converted to AC through an inverter and adjusted to a frequency of 60 Hz per second to be used as the starting power for the user and the generating motor (5) applied in this embodiment.

[0099] The starting power of the above-mentioned generating motor (5) may use the power of the Korea Electric Power Corporation currently in use.

[0100] In addition, the AC generator, which is a synchronous generator, operates on the principle that the armature is fixed and the field rotor rotates. The armature, which is the stator, is three-phase 380V, and the armature windings are arranged such that one phase is positioned at an angle of 0° around the axis of rotation, the second phase is positioned at a circular angle of 120° away, and the third phase is positioned at a circular angle of 240° away.

[0101] The three phases of the above AC generator are 380V, and in a Y connection, the wire connecting the three phases together is the neutral wire.

[0102] If the neutral wire and one of the three phases (one wire) are used together, it becomes 220V single phase.

[0103] In order to achieve a frequency of 60 Hz per second in the generator (4) through the mechanical configuration of the armature, which is the stator of the above-mentioned alternator, and the field, which is the rotor, the speed at which the blade rotation shaft (2) is rotated is determined in the generator design, and the determined value becomes the value that determines the motor rotation speed of the generating motor (5) that rotates the blade rotation shaft (2) at a constant speed, which is applied to the wind power generation system (1) and the power generation method of the present embodiment, and becomes the frequency of 60 Hz per second of the power produced by the generator (4).

[0104] If the frequency per second of the power produced by the above alternator is 50[Hz] or 70[Hz], it means that the rotation of the field, which is the rotor of the generator (4), is slow or fast. This is because the speed at which the magnetic flux [Φ] (magnetic field) is cut is not constant, so the sine wave of the armature reaction of the generator (4) should normally be in phase (when the time at which the voltage and current are generated is the same), but an abnormal phase difference (when there is a slight time difference between the current and the voltage) can be said to have occurred.

[0105] At this time, if the irregular frequency of 50[Hz] or 70[Hz] of the generated power is adjusted to a frequency of 60Hz per second using the cyclo converter (7) and supplied to the user, there is no problem with power supply. However, since the rotational speed of the field, which is the rotor of the generator (4), is not constant, the generator (4) cannot produce the maximum power it has. If the rotational speed of the rotor, which is the field of the generator (4), is irregular, a phase difference (where there is a slight time difference between voltage and current) which is an armature reaction occurs, causing the magnetic flux [Φ] (magnetic field) generated in the field to decrease and reactive power to be generated. In this case, more current (A) flows through the armature winding, which is the stator of the generator (4), than when the time at which voltage and current are generated coincides, causing the power factor to decrease and power production to decrease.

[0106] A method to improve the disadvantage that heat is generated in the generator (4) and affects the insulation and lifespan of the armature winding is to set the rotational speed of the blade rotation shaft (2) to match the mechanical configuration of the generator (4) with a frequency of 60 Hz per second, and to pre-set the motor rotational speed of the generating motor (5) to match the frequency of the generator (4) with 60 Hz per second, and then apply the motor rotational speed of the generating motor (5) to operate.

[0107]

[0108] The artificial intelligence wind power generation system (1) according to the present embodiment, which is formed in this way, further includes a wind speed sensor (81) configured to detect the intensity of wind pressure supplied to the generator (4) in the moving space and to transmit the detected wind speed detection data to a digital controller (6).

[0109] The digital controller (6) can drive and control the rotational speed of the generating motor (5) to form a wind speed that generates power at a frequency of 60 Hz per second in the generator (4) calculated in advance based on the wind speed detection data.

[0110] That is, based on the wind speed detection data according to the intensity of the wind pressure in the moving space obtained through the wind speed sensor (81), the digital controller (6) calculates and controls the generation motor (5) to form a wind speed that generates power at a frequency of 60 Hz per second in the generator (4).

[0111] Accordingly, power with a frequency of 60 Hz per second is supplied to the above-mentioned cyclo converter (7).

[0112] The artificial intelligence wind power generation system (1) according to the present embodiment as described above further includes a rotational speed measuring sensor (82) configured to be provided in a rotating shaft bushing or bearing (3) to detect the number of rotations of the blade rotating shaft (2) and to transmit the detected number of rotations to a digital controller (6).

[0113] The above digital controller (6) can drive and control the rotational speed of the generating motor (5) to form a wind speed that is tailored to form a rotational speed of the blade rotation shaft (2) that generates power at a frequency of 60 Hz per second in the generator (4) calculated in advance by performing calculations based on rotational speed detection data.

[0114] That is, based on the rotational speed detection data according to the rotational speed of the wing rotation axis (2) obtained through the rotational speed measurement sensor (82), the digital controller (6) calculates and controls the driving motor (5) to form a wind speed that generates power at a frequency of 60 Hz per second in the generator (4).

[0115] Accordingly, power with a frequency of 60 Hz per second is supplied to the above-mentioned cyclo converter (7).

[0116] The artificial intelligence wind power generation system (1) according to the present embodiment, which is formed in this manner, further includes a frequency measuring sensor (83) that is electrically connected to a generator (4) and configured to detect the frequency per second generated by the generator (4) and transmit the detected frequency detection data to a digital controller (6).

[0117] The digital controller (6) can drive and control the rotational speed of the generating motor (5) to form a wind speed that is adjusted to form a rotational speed of the blade rotation shaft (2) that generates power at a frequency of 60 Hz per second in the generator (4) calculated in advance based on frequency detection data.

[0118] That is, based on the frequency detection data according to the frequency per second of the generator (4) obtained through the frequency measurement sensor (83), the digital controller (6) calculates and controls the driving motor (5) to form a wind speed that generates power at a frequency of 60 Hz per second in the generator (4).

[0119] Accordingly, power with a frequency of 60 Hz per second is supplied to the above-mentioned cyclo converter (7).

[0120] The artificial intelligence wind power generation system (1) according to the present embodiment as described above may further include a digital brake (84) that is controlled and driven through a digital controller (6) to variably control the rotation of the blade rotation axis (2) to match the mechanically configured frequency of 60 Hz per second of the generator (4) when the frequency data measured by the frequency measuring sensor (83) placed in the generator (4) exceeds the mechanically configured frequency of 60 Hz per second of the generator (4).

[0121] That is, when the intensity of the wind pressure formed in the above moving space increases significantly, and the rotational speed of the wing rotation shaft (2) increases significantly and exceeds the mechanically configured frequency of 60 Hz per second of the generator (4), the rotational speed of the wing rotation shaft (2) is reduced by the digital brake (84) controlled and driven through the digital controller (6) to form a rotational speed that matches the frequency of 60 Hz per second.

[0122] Accordingly, the mechanically configured frequency of 60 Hz per second of the generator (4) is stably implemented.

[0123]

[0124] Meanwhile, the artificial intelligence wind power generation system (1) according to the present embodiment further includes a power transmission gear member (9) having a movable bevel gear (91) axially coupled to a blade rotation axis (2) and a driven bevel gear (93) provided on a driven gear shaft (92) connected to the rotation axis of the generator (4) and gear-coupled with the movable bevel gear (91).

[0125] That is, in the process of transmitting the rotational force formed at the wing rotation axis (2) to the generator (4) through the gear coupling of the movable bevel gear (91) and the driven bevel gear (93) constituting the power transmission gear member (9), the transmission is made stable regardless of the transmission angle, thereby reducing design limitations on the generator (4) and improving structural stability and usability.

[0126] The artificial intelligence wind power generation system (1) according to the present embodiment, which is formed in this manner, may further include an induction means (200) configured to be provided between the generating motor (5) and the generating blade (21) to induce wind pressure generated from the generating motor (5) toward the generating blade (21).

[0127] That is, as the above-mentioned induction means (200) is configured to induce and apply wind pressure generated from the generating motor (5) to the optimal position for the generating blade (21), the rotational efficiency of the generating blade (21) can be maximized.

[0128] The above-mentioned induction means (200) may be formed as a ‘funnel’ shaped ‘tube’ in which the inlet for wind pressure to enter is formed wide and the outlet for exhaust is formed narrow so as to concentrate the wind pressure moving in the moving space towards the center.

[0129] That is, the wind pressure of the above-mentioned moving space is guided to the center through the ‘funnel’-shaped guiding means (200), thereby increasing the rotational efficiency of the power generation blade (21).

[0130] The artificial wind (wind pressure) formed through the above-mentioned generating motor (5) causes a phenomenon where it is directed from the center to the outer edge in the movement space of the artificial wind structure (100), and a vortex phenomenon occurs behind the generator (4).

[0131] Accordingly, the wind pressure is induced to an optimal position that increases the rotational efficiency of the generator blade (21) through the above-mentioned induction means (200), thereby maximizing the power generation efficiency of the generator (4).

[0132] The artificial intelligence wind power generation method according to the present invention generates artificial wind between the aforementioned cavity where wind pressure moves, and is configured to generate power by converting wind pressure into electrical energy provided in the moving space.

[0133] That is, the wind speed formed in the above moving space is formed to maintain a wind pressure that is matched to a frequency of 60[Hz] per second for the electric energy generated by the generator (4) through automatic control with artificial intelligence applied.

[0134] Accordingly, power of 60 Hz per second can be produced and supplied through the above-mentioned cyclo converter (7) to improve the quality of use.

[0135]

[0136] The artificial intelligence wind power generation system (1) and the power generation method according to the present embodiment, as described above, are characterized by the technical configuration that generates wind power (wind) consistently and continuously for the artificial wind structure (100) that moves while generating wind power (wind) through the driving of the generating motor (5), and generates self-power using a generator (4) that generates power based on the wind power, and also improves the quality of use by producing and supplying power with a frequency of 60[Hz] per second through the cyclo converter (7) to which digital control by artificial intelligence is applied to the generating motor (5).
