[0042] As mentioned above, existing power generation systems suffer from poor stability. Specifically, wave energy, as a renewable resource, holds enormous potential, but existing wave energy systems generally suffer from complex structures, poor reliability, and high maintenance costs. Traditional point-suction power generation systems are often subject to the intense impact of waves, and most of their mechanical components are exposed underwater or on the surface, making them susceptible to seawater corrosion, leading to mechanical wear and structural fatigue, and thus poor stability of the overall power generation system.

[0043] To address the above issues, embodiments of the present application provide a power generation system comprising an energy capture module and an energy conversion module. The energy capture module is configured to change its position based on external energy. The energy conversion module is connected to the energy capture module and configured to change its capacitance when the energy capture module's position changes.

[0044] In this way, by combining only the energy capture module and the energy conversion module, the changes in the position of the energy capture module drive the changes in the electric field within the energy conversion module, causing its capacitance to fluctuate and thus storing electrical energy. This simplifies the overall structure of the power generation system and improves its stability.

[0045] It should be noted that the power generation system and power generation method provided in this application can be applied to the field of power generation technology. The above is only an example and does not limit the application field of the power generation system and power generation method provided in this application.

[0046] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0047] Figure 1 A schematic diagram of the structure of a power generation system provided in an embodiment of the present application. Figure 1 As shown, the power generation system includes: an energy capture module 100 and an energy conversion module 200;

[0048] The energy capture module 100 is used to change its own position according to external energy;

[0049] The energy conversion module 200 is connected to the energy capture module 100 and is configured to change its own capacitance when the position of the energy capture module 100 changes.

[0050] Specifically, the energy capture module 100 interacts with the outside world, can receive external energy transmitted to itself, and change its own position according to the external energy. For example, the position of the energy capture module 100 is relatively stable. When an upward force is applied to the energy capture module 100, the energy capture module 100 can move upward based on the force. There can be many objects that generate this force, such as animals, wind, waves, and so on. The energy capture module 100 is connected to part of the structure of the energy conversion module 200. When its own position changes, it can synchronously change the structure of the energy conversion module 200, thereby causing the electric field in the energy conversion module 200 to change, causing the capacitance in the energy conversion module 200 to fluctuate, thereby achieving the purpose of power generation.

[0051] As an implementation method, regarding how to design a power generation system, the power generation system further includes: an external load 300;

[0052] The external load 300 is connected to the energy conversion module 200;

[0053] Used to output the electrical energy stored in the energy conversion module 200.

[0054] Specifically, Figure 2 A schematic diagram of the structure of an external load provided in an embodiment of the present application. Figure 2 As shown, the external load 300 is connected to the energy conversion module 200. When the electrical energy in the energy conversion module 200 reaches a certain level, the power generation system will output the stored electrical energy through the external load 300 and convert the electrical energy into usable electricity.

[0055] As an embodiment, regarding how to design the energy conversion module 200, the energy conversion module 200 includes: a first parallel plate capacitor 210;

[0056] The first parallel plate capacitor 210 includes: a first upper electrode plate 211 and a first lower electrode plate 212 arranged in parallel along a first direction;

[0057] The position of the first upper electrode plate 211 is fixed;

[0058] The first lower electrode plate 212 is rigidly connected to the energy capture module 100 .

[0059] Figure 3 This is a schematic diagram of the structure of an energy conversion module provided in an embodiment of the present application. Figure 3As shown, the energy conversion module 200 provided in an embodiment of the present application can be a parallel plate capacitor, namely a first parallel plate capacitor 210. The two electrode plates of the first parallel plate capacitor 210 (a first upper electrode plate 211 and a first lower electrode plate 212) are arranged parallel to each other along a first direction, with one of the electrode plates being fixed in position and the other being rigidly connected to the energy capture module 100. Specifically, the first upper electrode plate 211 can be fixed in position and affixed to a fixed structure, while the first lower electrode plate 212 is rigidly connected to the energy capture module 100. It is understood that the first direction can be any direction, but to improve power generation efficiency, the first direction should be associated with the movable direction of the energy capture module 100, that is, the plate planes of the first upper electrode plate 211 and the first lower electrode plate 212 should be arranged perpendicular to the movable direction of the energy capture module 100. For example, establishing a coordinate system XYZ, assuming that the energy conversion module 200 can move in the +Z and -Z directions according to external energy, the first direction should be +Z or -Z.

[0060] As an implementation method, regarding how to design the energy receiving mode, the energy capture module 100 is a float;

[0061] The float floats on the sea surface, and floats along the second direction or the first direction as the waves rise or fall, and simultaneously drives the first lower electrode plate 212 to move along the second direction or the first direction;

[0062] The second direction is the opposite direction of the first direction.

[0063] Specifically, the power generation system provided in the embodiments of the present application can be used to convert wave energy into electrical energy. In this case, the energy capture module 100 that interacts with external energy can be a float. The float is placed in the ocean, floating on the surface and bobbing up and down with the waves. It is understood that when waves rise, the float is driven upward, and the first lower electrode plate 212, rigidly connected to the float, moves upward in tandem. When waves recede, the float is driven downward, and the first lower electrode plate 212, rigidly connected to the float, moves downward in tandem. If downward (-Z direction) is defined as the first direction and upward (+Z direction) as the second direction, then when waves rise, the float drives the first lower electrode plate 212 to move in the second direction. This reduces the distance between the two electrode plates of the first parallel plate capacitor 210, reducing the amount of electrical energy stored in the capacitor. Similarly, when waves recede, the float drives the first lower electrode plate 212 to move in the first direction. This increases the distance between the two electrode plates of the first parallel plate capacitor 210, increasing the amount of electrical energy stored in the capacitor.

[0064] As an embodiment, regarding how to design the energy conversion module 200, the energy conversion module 200 further includes: a second parallel plate capacitor 220;

[0065] The second parallel plate capacitor 220 includes: a second upper electrode plate 221 and a second lower electrode plate 222 arranged in parallel along the first direction;

[0066] The position of the second lower electrode plate 222 is fixed;

[0067] The second upper electrode plate 221 is rigidly connected to the energy capture module 100 .

[0068] Specifically, in order to ensure the stability of the power generation system, a second parallel plate capacitor 220 can be set simultaneously and designed opposite to the first parallel plate capacitor 210. Specifically, Figure 4 A schematic diagram of the structure of a second parallel plate capacitor provided in an embodiment of the present application. Figure 4 As shown, continuing with the upward (+Z direction) as the second direction and the downward (-Z direction) as the first direction as an example, the second upper electrode plate 221 and the second lower electrode plate 222 in the second parallel plate capacitor 220 are arranged in parallel along the first direction. Unlike the first parallel plate capacitor 210, it is necessary to fix the position of the second lower electrode plate 222 and fix it on the fixed structure, while the second upper electrode plate 221 is rigidly connected to the energy capture module 100 (float).

[0069] As an embodiment, in order to change the capacitance of the second parallel plate capacitor 220 , when the float floats along the second direction or the first direction, the second upper electrode plate 221 is simultaneously driven to move along the second direction or the first direction.

[0070] Specifically, in conjunction with the aforementioned configuration of the second parallel plate capacitor 220, the float floats on the sea surface and rises and falls with the waves. When the waves rise, they drive the float upward, and the second upper electrode plate 221, rigidly connected to the float, simultaneously moves upward. When the waves recede, they drive the float downward, and the second upper electrode plate 221, rigidly connected to the float, simultaneously moves downward. Continuing with the aforementioned directions, when the waves rise, the float drives the second upper electrode plate 221 to move in the second direction. This increases the distance between the two electrode plates of the second parallel plate capacitor 220, increasing the amount of electrical energy stored in the capacitor. Similarly, when the waves recede, the float drives the second upper electrode plate 221 to move in the first direction. This decreases the distance between the two electrode plates of the second parallel plate capacitor 220, decreasing the amount of electrical energy stored in the capacitor. It can be understood that the reverse dual parallel plate capacitor structure set in the embodiment of the present application, when there is external energy (wave energy) interacting with the float, regardless of whether the float floats up or down, there is always a parallel plate capacitor being charged, thereby ensuring the stability of the power generation system.

[0071] As an embodiment, regarding how to design the energy conversion module 200, the energy conversion module 200 is designed to be detached from the sea surface.

[0072] Specifically, the first and second parallel-plate capacitors 210 and 220 provided in this embodiment of the present application are both designed to be detached from the sea surface. Through the rigid connection between the float and the capacitor plates, wave energy is directly and efficiently converted into electrical energy, while preventing seawater corrosion on electrical components, thereby improving the system's stability, robustness, and service life. Furthermore, the simplified mechanical structure, unlike common point-absorption devices, not only enhances the stability of the power generation system but also effectively improves its fatigue resistance.

[0073] As an implementation method, regarding how to design a power generation system, the power generation system further includes: an energy detection module;

[0074] The energy detection module is used to detect the electrical energy stored in the energy conversion module 200;

[0075] When the electric energy stored in the energy conversion module 200 reaches a first preset threshold, the external load 300 is controlled to output the electric energy stored in the energy conversion module 200 .

[0076] Specifically, when waves propel the float up and down, the first and second parallel plate capacitors 210 and 220 experience relative displacement, leading to changes in the electric field within the capacitors. This change converts the wave's mechanical energy into electrical energy, which is stored in the capacitors. The relative movement of the upper and lower plates determines how much electrical energy the capacitors can store, and determining the energy output at the required level is crucial. It is understood that when the float reaches its maximum downward displacement, the energy in the first parallel plate capacitor 210 is at its maximum. If this energy is released (the field strength decreases), the resistance to the float's upward movement from the first capacitor will be significantly reduced, allowing the second parallel plate capacitor 220 to store more energy. Similarly, when the float reaches its maximum upward displacement, the energy in the second parallel plate capacitor 220 is at its maximum. If this energy is released (the field strength decreases), the resistance to the float's downward movement from the second capacitor will be significantly reduced, allowing the first parallel plate capacitor 210 to store more energy. To this end, an energy detection module can be provided to detect the electrical energy stored in the energy conversion module 200. The distance that the float can typically move up and down is analyzed in conjunction with the wave size in the sea area where the power generation system is located. Furthermore, a first preset threshold value is established based on the maximum distance that the float can pull the first lower electrode plate 212 or the second upper electrode plate 221 to form between the first lower electrode plate 212 and the first upper electrode plate 211 or the second lower electrode plate 222. For example, when the float can pull the first lower electrode plate 212 to form a maximum distance of 10 cm between the first lower electrode plate 212 and the first upper electrode, the electrical energy stored in the first parallel plate capacitor 210 when the distance between the first lower electrode plate 212 and the first upper electrode is 10 cm can be set as the first preset threshold value.

[0077] In addition, the embodiment of the present application provides an example of calculating the power that can be captured by the power generation system under wave conditions, as follows:

[0078] Assume the float radius is 1.5 mm / draft is 1.0 mm, the wave period is 3.0 s / wave height is 1.0 m, and the power generation system adopts a control strategy to maintain the plate charge Q_init constant while pulling the plates. Discharge to Q_end is completed when the plate spacing is maximized (maximum stored energy). The float then restores the plates to their original position and recharges them to Q_init. It is worth noting that in this case, the electric field force remains constant during the pulling of the plates. Given the above system structure, one of the two parallel plate capacitors is always absorbing energy while the other is releasing it. For example, when the float moves downward, the spacing between the two plates of the first parallel plate capacitor increases, absorbing the float's energy, while the spacing between the two plates of the second parallel plate capacitor decreases, transferring energy to the float. At this point, the charge on the first parallel plate capacitor is Q_init, while the charge on the second parallel plate capacitor is Q_end. If Q_end is 0, there is no reverse power transfer to the float, increasing wave capture efficiency.

[0079] The simulation results show that wave energy extraction and power generation can be achieved under appropriate parameter settings. The current control variable is the plate electric field force, and the design variable is the plate mass. The other parameters of the parallel plate capacitor are calculated as follows. Assuming that the plate thickness of the parallel plate capacitor is 10 cm and the mass is 100 kg, the area can be calculated based on the mass to be approximately 12.5 m 2 In order to maximize energy extraction, we hope that the electric field force is completely discharged, that is, Q_end=0, that is, the corresponding electric field force is 0. The initial charge is related to the initial electric field force. Assuming that the initial electric field force is 1000N, the expression of the initial charge is as follows:

[0080] ;

[0081] As the float drags the plates, the capacitance decreases as the distance increases, while the voltage between the plates increases. If the initial distance between the plates is 10 mm, the initial capacitance of the parallel plate capacitor is as follows:

[0082] ;

[0083] ;

[0084] ;

[0085] Thus, according to the simulation, the maximum distance between the plates is about 3m, and further we can get:

[0086] ;

[0087] ;

[0088] ;

[0089] At the same time, during the dragging process, the electric field strength remains unchanged, as follows:

[0090] .

[0091] In summary, the power generation system provided by the present application includes an energy capture module and an energy conversion module. Among them, the energy capture module is used to change its own position according to external energy. The energy conversion module is connected to the energy capture module and is used to change its own capacitance when the energy capture module's own position changes. In this way, only the energy capture module and the energy conversion module are combined, and the change in the energy capture module's own position drives the change in the electric field in the energy conversion module, causing its capacitance to fluctuate, thereby storing electrical energy. The overall structure of the power generation system is simplified and the stability of the power generation system is improved.

[0092] Figure 5 This is a flow chart of a power generation method for a power generation system provided in an embodiment of the present application. Figure 5 As shown, the power generation method provided in the embodiment of the present application may include:

[0093] S501: Configure the energy capture module and the energy conversion module.

[0094] In practical applications, it is first necessary to configure the energy capture module and the energy conversion module, set the energy capture module in a position where it can interact with external energy, and connect part of the structure of the energy conversion module to the energy capture module. For example, if the energy capture module is a float and the energy conversion module is a parallel plate capacitor, the float should be set in the ocean, floating on the sea surface, and enabled to float up and down with the rise and fall of the waves. Furthermore, one of the electrode plates in the parallel plate capacitor is fixed in position, and the other electrode plate is rigidly connected to the float. It can be understood that in order to improve the power generation efficiency, the setting direction of the parallel plate capacitor should be related to the movable direction of the float, that is, when the float can float up and down in a direction perpendicular to the sea level based on the rise and fall of the waves, the plate planes of the two electrode plates in the parallel plate capacitor should be configured parallel to the sea level.

[0095] S502: Utilize the energy capture module to receive external energy, and adjust the position of the energy capture module according to the external energy.

[0096] In practice, a configured energy capture module can interact with external energy, receiving it and adjusting its position accordingly. Continuing with the previous explanation, the energy capture module is a float, and the energy conversion module is a parallel plate capacitor. The float floats on the sea surface, primarily receiving wave energy and bobbing up and down based on the waves.

[0097] S503: Adjusting the capacitance of the energy conversion module based on the change in the position of the energy capture module.

[0098] In practical applications, since the energy capture module and part of the energy conversion module are rigidly connected, changes in the position of the energy capture module can affect the overall structure of the energy conversion module, causing changes in the electric field within the energy conversion module and fluctuations in the capacitance of the energy conversion module. Specifically, assuming the energy conversion module is a first parallel plate capacitor, its first upper electrode plate and first lower electrode plate are arranged parallel to each other along a first direction (-Z direction), the first upper electrode plate is fixed in position, and the first lower electrode plate is rigidly connected to the float. When the waves rise, they can drive the float upward (+Z direction). At this time, the first lower electrode plate, which is rigidly connected to the float, simultaneously moves upward (+Z direction), reducing the distance between the two electrode plates of the first parallel plate capacitor and reducing the amount of electrical energy stored in the capacitor. When the waves recede, they drive the float downward (-Z direction). At this time, the first lower electrode plate, which is rigidly connected to the float, simultaneously moves downward (-Z direction), increasing the distance between the two electrode plates of the first parallel plate capacitor and increasing the amount of electrical energy stored in the capacitor.

[0099] In addition, with respect to how to output the stored electrical energy, the above-mentioned power generation system further includes: an external load;

[0100] The method further comprises:

[0101] The electric energy stored in the energy conversion module is outputted by utilizing the external load.

[0102] In practical applications, when the energy conversion module stores a certain amount of electrical energy, the power generation system can output this stored energy through an external load and convert it into usable electricity. Furthermore, by adjusting the design parameters of the energy conversion module (parallel plate capacitor), the power generation system's energy conversion efficiency can be optimized according to different sea conditions and wave characteristics.

[0103] In summary, the power generation method provided by the present application includes: first configuring an energy capture module and an energy conversion module. Then using the energy capture module to receive external energy, and adjusting the position of the energy capture module according to the external energy. Finally, based on the change of the position of the energy capture module, the capacitance of the energy conversion module is adjusted. In this way, only the energy capture module and the energy conversion module are combined, and the change of the position of the energy capture module itself is used to drive the change of the electric field in the energy conversion module, so that its capacitance fluctuates, and then the electrical energy is stored. The overall structure of the power generation system is simplified and the stability of the power generation system is improved.
