Description

Solar assisted power generation system and method

This case is about a power generation system and method, in particular, about a solar-assisted power generation system and the operation method of the power generation system.

Traditional wind power generation modules are usually made by winding insulated wires on a bobbin or core into multiple turns of coils to form an inductor. The inductor is used as a rotor, usually positioned between a stator with magnetic parts. When the inductor rotates in a magnetic field, the rotor coils cut the magnetic field lines of the magnetic field in a circular or arc-shaped trajectory. However, because there is magnetic attraction between the core of the inductor and the stator, this magnetic attraction will become resistance to the wind power module during the power generation process and reduce the speed of the rotor, and even lead to a situation where the wind force is not enough to overcome the magnetic attraction and cannot drive the blade mechanism, thereby reducing the power generation efficiency of the wind power module.

In addition, during the power generation process of the wind turbine module, the weight of the fan mechanism, rotor, drive shaft between the fan mechanism and rotor, gears, etc. will bring resistance to the wind turbine module, thereby reducing the speed of the rotor. When such weight is too heavy, the wind force may not be enough to overcome the friction generated by the weight and thus fail to push the fan mechanism, reducing the power generation efficiency of the wind turbine module.

In addition, the traditional drum-type power generation module is equipped with coils on both sides of the cylindrical surface of the shaft, using wind or water power to rotate the shaft, thereby rotating the coil and cutting the magnetic field lines with a circular or arc-shaped trajectory to generate an induced current. However, the coils of the traditional drum-type power generation module will also produce a charge collection effect (also known as the "skin effect" or "epidermal effect", English: Skin Effect), and more electrons will gather on the side of the coil close to the magnet. In the process of power generation, due to the thermal effect of the current, the heat energy generated will be concentrated on the side of the coil close to the magnet, resulting in a shortened coil life.

Therefore, it is an important topic to propose a generator that can avoid the magnetic attraction between the iron core of the inductor and the stator, solve the friction generated by the weight of the blade mechanism, rotor, drive shaft, gears, etc. between the blade mechanism and the rotor, and reduce the power generation efficiency of the wind power generation module, and alleviate the problem of shortened coil life due to the charge collection effect.

In order to solve the above problems, one embodiment of the present case provides a solar-assisted power generation system, which includes a solar power generation module, a wind power or hydropower generation module and an electric energy storage unit. The solar power generation module uses solar energy to generate a first electric energy. The wind power or hydropower generation module has a motor, a transmission mechanism and a fan mechanism. The motor uses the first electric energy to convert the first electric energy into a kinetic energy, and the kinetic energy is used to overcome the maximum static friction force for driving a transmission mechanism to rotate and for driving a fan mechanism to rotate. The transmission mechanism is connected to the motor, and the transmission mechanism is driven by torque to drive the fan mechanism to rotate. The fan mechanism is connected to the transmission mechanism. Wind or water force drives the transmission mechanism and the fan mechanism to rotate, so that a stator and a rotor of the wind or water power generation module generate a second electric energy. The electric energy storage unit is connected to the solar power generation module and the wind or water power generation module to store the first electric energy and the second electric energy.

In some embodiments, the wind or hydroelectric power generation module of the solar-assisted power generation system further includes a speed change device. The speed change device is connected to the fan mechanism, and has a transmission belt and a transmission wheel. The speed change device uses the inertial force (commonly known as "centrifugal force") generated by the fan mechanism to adjust the relative position relationship between the transmission belt and the transmission wheel (hereinafter referred to as "gear"), thereby achieving that the wind or hydroelectric power generation module can automatically adjust the gear of the speed change device according to the rotation speed of the fan mechanism.

In some embodiments, the solar-assisted power generation system further includes a sensing control processing unit. The sensing control processing unit includes a sensor, a processor, and a controller. The sensor is used to measure wind speed, wind pressure, the speed of the transmission mechanism, the speed of a gear of the transmission device, and the physical parameters that can directly or indirectly calculate the speed of the fan mechanism, and obtain a measurement value. The processor is connected to the sensor and is used to calculate a control signal based on the measurement value. The controller is connected to the processor and is used to switch the gear of the transmission device according to the control signal.

Another embodiment of the present invention provides an electronically controlled variable speed solar-assisted power generation system, which includes a solar power generation module, a wind power or hydropower generation module as described in any of the previous embodiments, an electric energy storage unit, and a sensing control processing unit. The sensing control processing unit is connected to the fan mechanism, and the sensing control processing unit includes a sensor, a processor, and a controller. The sensor is used to measure wind speed, wind pressure, the speed of the transmission mechanism, the gear speed of the speed change device, and any other physical parameters that can directly or indirectly calculate the speed of the fan mechanism, and obtain a measurement value. The processor is connected to the sensor and is used to calculate a control signal according to the measurement value. A controller connected to the processor is used to switch the gear of the transmission device according to the control signal.

In some embodiments, the wind or hydroelectric power generation module of the solar-assisted power generation system mainly utilizes the parallel relative rotation of the magnetic disk and the wire drum to cut the magnetic lines of force, generate induced electromotive force and induced current, and complete power generation. Since the coil group of this case is arranged in layers and intervals, this wind or hydroelectric power generation module is more conducive to the three-phase power circuit system, and thus is conducive to meeting the industry's demand for high-power current. In addition, in some embodiments, there are magnetic disks on both sides of the wire drum, which can alleviate the problem of uneven temperature on both sides of the coil group derived from the charge collection effect of traditional generators, thereby extending the life of the coil group. In addition to the above power generation modules, some embodiments of this case also propose power generation systems that can be applied to wind or hydropower generation modules or other parallel-axis, vertical-axis, etc. power generation modules, by actively consuming electrical energy to overcome the maximum static friction, so as to bring about a better power generation efficiency of the generator. The consumed electrical energy mainly comes from solar energy, so some embodiments of this case mainly combine solar power generation and wind power generation to produce an effect greater than the effect of the two operating separately.

In some embodiments, a wind or hydroelectric power generation module includes a stator and a rotor. The stator includes a first coil and a second coil. The rotor includes a first magnetic disk and a second magnetic disk. The first magnetic disk, the first coil, the second magnetic disk and the second coil are arranged sequentially, layered and spaced. The first magnetic disk and the second magnetic disk each have at least one magnetic component, and the first coil and the second coil each have at least one coil set. Only one of the first magnetic disk and the second magnetic disk is connected to a transmission mechanism while the other is not connected to the transmission mechanism; through the magnetic attraction between a magnetic component of the first magnetic disk and a magnetic component of the second magnetic disk, the first magnetic disk can link the second magnetic disk to rotate when it rotates. Among them, when the transmission mechanism completes at least one rotation, a magnetic field generated by the magnetic component must pass through a coil surface of the coil group, and the magnetic field is cut by the coil group. As the transmission mechanism rotates, the magnetic flux of the magnetic field passing through the coil group changes, thereby causing the coil group to generate current and electrical energy. Among them, the magnetic field has a magnetic field vector, which refers to the direction of the magnetic field line, and is also the direction from the N pole of a magnet to the S pole of another magnet. In other words, it is the direction from the S end inside the magnet to the N end of the magnet. The coil surface has a normal vector of the coil surface, and the angle between the magnetic field vector and the normal vector of the coil surface is always between 0 degrees and 60 degrees.

In some embodiments, the rotor further includes a third magnetic disk having at least one magnetic component. The second coil is positioned between the second magnetic disk and the third magnetic disk. The magnetic component of the first magnetic disk includes at least two first magnetic elements, the magnetic component of the second magnetic disk includes at least two second magnetic elements, and the magnetic component of the third magnetic disk includes at least two third magnetic elements, wherein the magnetic field vector of at least one first magnetic element and the magnetic field vector of at least one second magnetic element have an angle between 0 degrees and 45 degrees, and the magnetic field vector of at least one second magnetic element and the magnetic field vector of at least one third magnetic element have an angle between 0 degrees and 45 degrees.

In some embodiments, at least one of the first bobbin and the second bobbin has a fixing structure, and at least one coil set is disposed in a coil box, and the user can install or remove the coil box from the fixing structure in a non-destructive manner.

In some embodiments, the first magnetic disk, the first wire disk, the second magnetic disk, and the second wire disk all have at least two notches.

In some embodiments, the first magnetic disk of the rotor is connected to the transmission mechanism, and at least one of the second magnetic disk and the third magnetic disk of the rotor is not connected to the transmission mechanism; wherein, in the case where both the second magnetic disk and the third magnetic disk are not connected to the transmission mechanism, the wind or hydroelectric power generation module achieves the effect of causing the first magnetic disk to rotate in conjunction with the second magnetic disk and the third magnetic disk through the magnetic attraction between the magnetic component of the first magnetic disk and the magnetic component of the second magnetic disk, and through the magnetic attraction between the magnetic component of the second magnetic disk and the magnetic component of the third magnetic disk. In the case where the second magnetic disk is connected to the transmission mechanism but the third magnetic disk is not connected to the transmission mechanism, the wind or hydroelectric power generation module achieves the effect of causing the second magnetic disk to rotate in conjunction with the third magnetic disk through the magnetic attraction between the magnetic components of the second magnetic disk and the magnetic components of the third magnetic disk.

In some embodiments, it further includes: a blade mechanism connected to the transmission mechanism.

In some embodiments, it further includes: a speed change device connected to the transmission mechanism and the fan mechanism, which has a transmission belt and a transmission wheel, wherein the speed change device uses the inertial force (commonly known as "centrifugal force") generated by the fan mechanism to adjust the relative position relationship between the transmission belt and the transmission wheel (hereinafter referred to as "gear"), thereby achieving that the wind power or hydropower generation module can automatically adjust the gear of the speed change device according to the rotation speed of the fan mechanism.

Another embodiment of the present case provides a solar-assisted power generation method, which is applied to rotate a blade mechanism of a wind or water power generation module of a power generation system, wherein the blade mechanism cannot rotate smoothly due to the influence of friction and gravity. The solar-assisted power generation method includes a solar power generation module of the power generation system using solar energy to generate a first electrical energy. Then, a motor of a wind or water power generation module of the power generation system uses the first electrical energy to convert the first electrical energy into kinetic energy, thereby directly driving a transmission mechanism of the wind or water power generation module to rotate. Then, the transmission mechanism drives the blade mechanism of the wind or water power generation module that was originally unable to rotate due to gravity or friction to rotate. Next, the fan mechanism uses wind power or water power to drive the transmission mechanism to rotate so that the power generation module generates a second electric energy, and the second electric energy is stored in an electric energy storage unit of the power generation module.

In some embodiments, the first electric energy in the solar-assisted power generation method is stored in an electric energy storage unit, and the electric energy storage unit is used to store the first electric energy and the second electric energy at the same time.

In some embodiments, the solar-assisted power generation method includes using a speed change device of a wind or hydroelectric power generation module to automatically adjust the relative position relationship (hereinafter referred to as "gear") between the transmission belt and the transmission wheel according to the inertial force (commonly known as "centrifugal force") generated by the fan mechanism, thereby achieving that the wind or hydroelectric power generation module can automatically adjust the gear of the speed change device according to the rotation speed of the fan mechanism.

In some embodiments, the solar-assisted power generation method further includes: using a sensor to measure a physical parameter that can directly or indirectly calculate the speed of the fan mechanism, and obtaining a measurement value. The aforementioned physical parameter that can directly calculate the speed of the fan mechanism is the speed of the fan mechanism or the speed of the transmission mechanism, etc. On the other hand, the aforementioned physical parameter that can be indirectly calculated refers to wind speed, wind pressure, etc. Then, a processor is used to calculate a control signal based on the measurement value. Then, a controller is used to switch the gear of the transmission device according to the control signal.

In summary, this case proposes a solar-assisted power generation system and a solar-assisted power generation method.

The aforementioned solar-assisted power generation system and method are particularly applicable to wind or hydropower generation. In some embodiments, the wind or hydropower generation module mainly rotates in parallel with the magnetic disk arranged in layers and intervals, so that the magnetic field is cut by the coil group, and the magnetic flux of the magnetic field through the coil group changes, thereby causing the power generation module to generate current and electric energy. In addition, when the wind is weak, the electric energy in the electric energy storage unit and the motor are used to make the wind or hydropower generation module overcome the maximum static friction and operate, thereby improving the power generation efficiency.

Please refer to FIG. 3 again, which is a three-dimensional schematic diagram of a wind or water power generation module according to an embodiment of the present invention. As shown in FIG. 3, the wind or water power generation module 2 has a motor 21, a transmission mechanism 22, a blade mechanism 23, a stator 24 and a rotor 25. The motor 21 uses the first electrical energy to generate a kinetic energy, and the kinetic energy is used to overcome the maximum static friction force for driving the transmission mechanism 22 to rotate and for driving the blade mechanism 23 to rotate. The transmission mechanism 22 is connected to the motor 21, and the transmission mechanism 22 is driven by torque to drive the blade mechanism 23 to rotate. The blade mechanism 23 is connected to the transmission mechanism 22, and the wind or water force drives the transmission mechanism 22 and the blade mechanism 23 to rotate, thereby causing the stator 24 and the rotor 25 of the wind or water power generation module to generate a second electrical energy.

Please refer to FIG. 3 again. In some embodiments, the wind or hydroelectric power generation module 2 further includes a speed change device 26. The speed change device 26 is connected to the fan mechanism 23, and the speed change device 26 has a transmission belt (not shown) and a transmission wheel (not shown).

The specific configuration of the stator 24 and the rotor 25 in this embodiment is described below. Please refer to Figures 3 and 4. Figure 3 is a top view schematic diagram of a wind or hydroelectric power generation module in an embodiment of the present case. Figure 4 is an exploded schematic diagram of the wind or hydroelectric power generation module 2 of Figure 1. The stator 24 includes a first wire drum 241 and a second wire drum 242 (hereinafter collectively referred to as "the first and second wire drums 241, 242"). The rotor 25 includes a first magnetic disk 251 and a second magnetic disk 252 (hereinafter collectively referred to as "the first and second magnetic disks 251, 252"). Please refer to Figure 5, Figure 5A and Figure 5B again. Figure 5 is a schematic top view of the wind or hydropower generation module of Figure 3, Figure 5A is a schematic cross-sectional view of the wind or hydropower generation module of Figure 3 along the A-A section line of Figure 5, and Figure 5B is a schematic cross-sectional view of the wind or hydropower generation module of Figure 3 along the B-B section line of Figure 5. The first magnetic disk 251, the first coil 241, the second magnetic disk 252 and the second coil 242 are arranged sequentially, layered and spaced. The first and second magnetic disks 251 and 252 both have at least one magnetic component M, and the first and second coils 241 and 242 both have at least one coil set C. The aforementioned "layered" arrangement means that the first wire coil 241 and the second wire coil 242 are separated by one of the first magnetic disk 251 and the second magnetic disk 252 in space, but the present case is not limited to this. In other embodiments, the first wire coil 241 and the second wire coil 242 can also be separated by both the first magnetic disk 251 and the second magnetic disk 252. In addition, in this embodiment, the "interval" arrangement refers to the "equally spaced" arrangement, and in other embodiments, the interval arrangement can also refer to the "non-equally spaced" arrangement. On the other hand, "interval" includes the interval between the first and second wire coils 241 and 242 and the interval between the first and second magnetic disks 251 and 252.

Please refer to FIG. 5A. In some embodiments, in addition to a first magnetic disk 251 and a second magnetic disk 252 of a magnetic component M, the rotor 25 also has a third magnetic disk 253. The third magnetic disk 253 also has a magnetic component M. The first magnetic disk 251, the second magnetic disk 252 and the third magnetic disk 253 are collectively referred to as "the first, second and third magnetic disks 251, 252, 253" below. The first, second and third magnetic disks 251, 252, 253 are arranged in sequence and at intervals. In this embodiment, from top to bottom, they are the first magnetic disk 251, the first line disk 241, the second magnetic disk 252, the second line disk 242 and the third magnetic disk 253. The first wire drum 241 is positioned between the first magnetic disk 251 and the second magnetic disk 252, and the second wire drum 242 is positioned between the second magnetic disk 252 and the third magnetic disk 253. The first, second and third magnetic disks 251, 252, 253, the first and second wire drums 241, 242 are fixed in the vertical direction so as not to slide up and down.

As shown in FIG. 5A , in this embodiment, only one of the first magnetic disk 251 and the second magnetic disk 252 is connected to a transmission mechanism 22 while the other is not connected to the transmission mechanism 22; through the magnetic attraction between a magnetic component M of the first magnetic disk 251 and a magnetic component M of the second magnetic disk 252, the first magnetic disk 251 can drive the second magnetic disk 252 to rotate when rotating. In other words, when the transmission mechanism 22 rotates, only the first magnetic disk 251 is directly driven by the mechanical force of the transmission mechanism 22, the second magnetic disk 252 is driven by the magnetic attraction between the first magnetic disk 251 and the second magnetic disk 252, and the third magnetic disk 253 is driven by the magnetic attraction between the second magnetic disk 252 and the third magnetic disk 253. In other embodiments, the first magnetic disk 251 and the second magnetic disk 252 are connected to the transmission mechanism 22, or the first magnetic disk 251 and the third magnetic disk 253 are connected to the transmission mechanism 22, or the first magnetic disk 251, the second magnetic disk 252 and the third magnetic disk 253 are all connected to the transmission mechanism 22.

As shown in FIG. 4 , in some embodiments, the wind or hydroelectric power generation module 2 has a shaft R. As shown in FIG. 5A and FIG. 5B , in this embodiment, the transmission mechanism 22 has a transmission shaft R _c , and the axial vector of the transmission shaft R _c of the transmission mechanism 22 is defined as the transmission axis. A bearing B' is provided between the first, second and third magnetic disks 251, 252, 253 and the shaft R. The first, second and third magnetic disks 251, 252, 253 are defined as having a rotation axis R _c ', and the axial vector of the rotation axis R _c ' is defined as the rotor axis. When the transmission mechanism 22 rotates, the first, second and third magnetic disks 251, 252, 253 rotate around the rotation axis R _c '. Although the transmission axis and the rotor axis are parallel to each other in this embodiment, in some embodiments, the transmission axis and the rotor axis may not be parallel to each other, and may even be perpendicular to each other. Therefore, the present invention can be applied to traditional vertical axis generators, horizontal axis generators or other types of generators.

As shown in FIG. 5A and FIG. 5B , the distribution position of the magnetic component M corresponds to the distribution position of the coil group C. As shown in FIG. 5A , in this embodiment, the magnetic component M can be distributed directly above the coil group C. When the transmission mechanism 22 completes at least one rotation, a magnetic field generated by the magnetic component M must pass through a coil surface Cp of the coil group C, and the magnetic field is cut by the coil group C. As the transmission mechanism 22 rotates, the magnetic field changes through the magnetic flux of the coil group C, thereby causing the coil group C of the wind or hydropower generation module 2 to generate induced electromotive force, induced current and electric energy.

The configuration of the magnetic component M is further described below. Please refer to FIG. 6, which is a three-dimensional schematic diagram of the first magnetic disk of the rotor of an embodiment of the present invention. As shown in FIG. 6, the first magnetic disk 251 includes four magnetic components M. In this embodiment, the second magnetic disk 252 and the third magnetic disk 253 are the same as the first magnetic disk 251, and the second magnetic disk 252 and the third magnetic disk 253 also include four magnetic components M. As shown in Figures 5A, 5B and 6, in the present embodiment, the first, second and third magnetic disks 251, 252, 253 each include four magnetic components M. For the convenience of explanation, the magnetic components M included in the first, second and third magnetic disks 251, 252, 253 are named as the first magnetic element _M1 , the second magnetic element _M2 and the third magnetic element _M3 . The first, second and third magnetic disks 251, 252, 253 include four first magnetic elements _M1 , four second magnetic elements _M2 and four third magnetic elements _M3 , respectively. However, the present case does not limit the number of the first magnetic element _M1 , the second magnetic element _M2 and the third magnetic element _M3 , and the first magnetic element _M1 , the second magnetic element _M2 and the third magnetic element _M3 may be, for example but not limited to, magnets, electromagnets or other materials or combinations capable of generating a magnetic field. As shown in FIG. 5A and FIG. 5B , two of the four first magnetic elements M ₁ have N poles facing upward and S poles facing downward, while the other two first magnetic elements M ₁ have S poles facing upward and N poles facing downward. The same situation is _{also seen in the second magnetic element M 2 and the third magnetic element M 3 . In some embodiments, two of the four second magnetic elements M 2 have N poles facing} upward and S poles facing downward, while the other two have S poles facing upward and N poles facing downward. On the other hand, in some embodiments, two of the four third magnetic elements M ₃ have N poles facing upward and S poles facing downward, while the other two have S poles facing upward _and N poles facing downward.

In addition, as shown in FIG6 , in this embodiment, in order to reduce the volume and weight of the first, second and third magnetic disks 251, 252 and 253 to improve power generation efficiency, the first magnetic disk 251 has at least two notch portions G ₁ , preferably four notch portions G ₁ . Similarly, the second and third magnetic disks 252 and 253 may also have at least two notch portions G ₁ , preferably four notch portions G ₁ .

The following is a detailed description of the configuration of the stator of the present invention. Please refer to FIG. 7 and FIG. 8, which are both three-dimensional schematic diagrams of the stator 24 of the first embodiment of the present invention. The difference between FIG. 7 and FIG. 8 is whether the cover of the coil box Cb is opened, where FIG. 7 is not opened, and FIG. 8 is opened. The detailed structure of the coil box _Cb can be referred to FIG. 9 and FIG. 10, which are both three-dimensional schematic diagrams of the coil box _Cb of the first embodiment of the present invention, where FIG. 9 is not opened, and FIG. 10 is opened.

As shown in FIG. 7 and FIG. 8 , in some embodiments, the first bobbin 241 has a fixing structure F, and in some embodiments, the second bobbin 242 has a fixing structure F. In some embodiments, both the first bobbin 241 and the second bobbin 242 have a fixing structure F, and at least one of the first bobbin 241 and the second bobbin 242 has a fixing structure F. The coil assembly C is disposed in a coil box C _b , and the user can install or remove the coil box C _b from the fixing structure F in a non-destructive manner. The non-destructive manner means that after installing or removing the coil box C _b from the fixing structure F in this manner, the function of the coil box C b or the fixing structure F will not be lost or impaired. Therefore, when the coil assembly C needs to be replaced, the user only needs to remove the coil box C _b from the fixing structure F in a non-destructive manner and open the coil box C _b . Then, the coil can be easily replaced. At the same time, this method is also conducive to the mass production of the coil assembly C and the coil box C _b .

As shown in FIG10 , the coil set C is used as an inductor element. The coil set C may be in a cylindrical shape, preferably in a cylindrical shape. The cylindrical object in the middle of the coil set C is only used to fix the shape and position of the coil, but it is not ruled out that the material is a magnetically permeable material. However, the cylindrical object in the middle of the coil set C will not rotate or move due to the magnetic field. Its function and purpose are different from the iron core in the traditional inductor element.

Please refer to FIG. 5A and FIG. 10 together. The coil surface _Cp of the coil assembly C refers to the plane where the closed loop is located. Furthermore, the coil surface _Cp can be divided into an upper coil surface and a lower coil surface (hereinafter collectively referred to as "the two ends of the coil surface _Cp "). Since the two ends of the coil surface _Cp of the coil assembly C in this case will cut the magnetic field and have changes in magnetic flux, they will both generate corresponding currents. Under the condition of generating the same electric energy, compared with the traditional power generation module, the heat energy generated by the thermal effect of the current is more evenly distributed on the two ends of the coil surface _Cp in this case, so that the temperature of one side of the coil assembly C is effectively reduced, thereby alleviating the problem of excessive temperature on one side of the coil assembly C caused by the charge collection effect.

Regarding the relative positional relationship between the magnetic field and the coil group C in this case, as shown in Figure 5A, the magnetic field has a magnetic field vector, which refers to the direction of the magnetic field lines, and is also the direction from the N pole of a magnet to the S pole of another magnet. In other words, it is the direction from the S end inside the magnetic component M to the N end inside the magnetic component M, and the coil surface _Cp has a normal vector _Cv of the coil surface. In this embodiment, the angle between the magnetic field vector and the normal vector Cv of the coil surface is always 0 degrees, that is, in this embodiment, the magnetic field vectors of the first, second, and third magnetic elements _M1 , _M2 , and _M3 are perpendicular to the plane where the coil surface _Cp is located; in other embodiments, the angle between the magnetic field vector and the normal vector _Cv of the coil surface is always between 0 degrees and 60 degrees. In other words, the angles between the magnetic field vectors of the first, second, and third magnetic elements M ₁ , M ₂ , and M ₃ and the plane where the coil surface C _p is located are fixed.

As shown in FIG5A , the angle between the magnetic field vector of at least one first magnetic element _M1 and the magnetic field vector of at least one second magnetic element _M2 is between 0 and 45 degrees, and the angle between the magnetic field vector of at least one second magnetic element _M2 and the magnetic field vector of at least one third magnetic element _M3 is between 0 and 45 degrees. Here, the magnetic field vector refers to the direction from the S end to the N end inside the first, second, and third magnetic elements _M1 , _M2 , and _M3 . In this embodiment, the angle between the magnetic field vectors of the first, second, and third magnetic elements _M1 , _M2 , and _M3 is 0 degrees, and they are parallel to each other.

As shown in FIG. 7 , in this embodiment, in order to reduce the volume and weight of the first and second coils 241 and 242 to improve power generation efficiency, the first coil 241 has at least two notches G ₂ , preferably four notches G ₂ . Similarly, the second coil 242 may also have at least two notches G ₂ , preferably four notches G ₂ .

Finally, another embodiment of the present invention provides a solar-assisted power generation method (not shown), which is applied to rotate a blade mechanism of a wind power or hydropower module of a power generation system, wherein the blade mechanism cannot rotate smoothly due to the influence of friction and gravity. Traditional wind turbines (or hydropower) generators must have sufficiently strong wind (or water power) to enable the wind turbine or hydropower generator to operate. If the wind power or water power is not enough to push the blades, the wind turbine or hydropower generator cannot generate electricity at all, and the power generation efficiency is zero. However, the present invention utilizes the principle that the maximum static friction force is significantly greater than the dynamic friction force, so that the generator first utilizes (consumes) a first electric energy stored in advance to overcome the maximum static friction force to start the generator, so that the generator can operate smoothly. When the generator operates smoothly, it is not necessary to provide the first electric energy, and the power generation efficiency of the generator is not zero. Therefore, the problem that the traditional wind turbine or hydroelectric generator must have sufficient wind power or water power to operate the wind turbine or hydroelectric generator can be solved. The solar-assisted power generation method in this embodiment includes a solar power generation module of the solar-assisted power generation system using solar energy to generate a first electric energy. Then, a motor of a wind power or hydroelectric power generation module of the solar-assisted power generation system uses the first electric energy to convert the first electric energy into a kinetic energy, and then directly drives a transmission mechanism of the wind power or hydroelectric power generation module to rotate. Then, the transmission mechanism drives the fan mechanism of the wind or water power generation module, which was originally unable to rotate due to gravity or friction, to rotate. Then, the fan mechanism uses wind or water power to drive the transmission mechanism to rotate so that the power generation module generates a second electric energy, and the second electric energy is stored in an electric energy storage unit of the solar energy-assisted power generation system.

In some embodiments, the first electric energy in the solar-assisted power generation method is stored in an electric energy storage unit, and the electric energy storage unit is used to store the first electric energy and the second electric energy at the same time.

In some embodiments, the solar-assisted power generation method includes using a speed change device of a wind or hydroelectric power generation module to automatically adjust the relative position relationship (hereinafter referred to as "gear") between the transmission belt and the transmission wheel according to the inertial force (commonly known as "centrifugal force") generated by the fan mechanism, thereby achieving that the wind or hydroelectric power generation module can automatically adjust the gear of the speed change device according to the rotation speed of the fan mechanism, thereby improving the power generation efficiency.

In some embodiments, the solar-assisted power generation method further includes: using a sensor to measure a physical parameter that can directly or indirectly calculate the speed of the fan mechanism, and obtaining a measurement value. The aforementioned physical parameter that can directly obtain the speed of the fan mechanism is the speed of the fan mechanism or the speed of the transmission mechanism, etc. On the other hand, the aforementioned physical parameter that can be indirectly calculated refers to wind speed, wind pressure, etc. Then, a processor is used to calculate a control signal based on the measurement value. Then, a controller is used to switch the gear of the transmission device according to the control signal. That is to say, this embodiment achieves more precise control by automatically switching the gear of the transmission device through electronic control to improve power generation efficiency.

In summary, this case proposes a solar-assisted power generation system and a solar-assisted power generation method. The aforementioned solar-assisted power generation system and method are particularly applied to wind power or hydropower generation. The solar-assisted power generation system mainly includes a solar power generation module, a wind power or hydropower generation module, a motor and an energy storage unit. When the wind is weak, the electric energy generated by the solar power generation module and the motor are used to make the aforementioned wind power or hydropower generation module overcome the maximum static friction and operate, thereby improving the power generation efficiency and achieving the complete use of renewable energy power generation equipment. In addition, in some embodiments, the wind or hydroelectric power generation module mainly rotates in parallel with the magnetic disk arranged in layers and intervals, so that the magnetic field is cut by the coil group, and the magnetic flux of the magnetic field through the coil group changes, thereby causing the power generation module to generate current and electric energy. Such a layered configuration can alleviate the problem of uneven temperature caused by the charge collection effect of the coil group during the power generation process. In addition, the solar-assisted power generation method mainly uses the electric energy generated by the solar power generation module and the motor to make the aforementioned wind or hydroelectric power generation module overcome the maximum static friction and operate, thereby improving the power generation efficiency, so as to achieve the complete use of renewable energy power generation equipment.
