Description

Technical Field

[0001] This application relates to the field of magnetically controlled power generation technology, and in particular to a flexible magnetically controlled power generation device with multiple energy sources including electrothermal energy. Background Technology

[0002] Wind power generation is currently one of the mainstream new energy power generation technologies in my country. The large-scale increase in installed wind power capacity has made the intermittent and highly volatile characteristics of wind power increasingly prominent, leading to ineffective grid absorption and frequent wind curtailment. At the same time, with economic development and further improvement in living standards, higher demands are being placed on the types and quality of energy in social production and daily life, especially on thermal energy. The concept of wind-heat systems has thus been proposed. This system converts all wind energy into thermal energy for reuse, effectively solving the problems of intermittent and volatile wind energy and possessing good economic benefits. However, this technical solution has relatively low overall efficiency, and thermal energy cannot be transmitted over long distances, making it unsuitable for the long distances between energy production and consumption in my country.

[0003] In response, a flexible magnetic control power generation technology that combines wind energy with electricity and heat has been proposed. This technology uses flexible magnetic control power generation equipment to convert wind energy into electricity and heat simultaneously. The technology first meets the energy demand of the power grid, and then converts excess wind energy into heat for storage or utilization. This solution can effectively improve the overall efficiency of the system and solve the problem of wind energy utilization.

[0004] In related technologies, to enhance the heating power of the heating part, a solution is adopted to drill holes and insert guide bars on the heating stator. Although this solution improves the heating power, it reduces the structural strength of the heating stator. Furthermore, the presence of holes and guide bars increases the torque pulsation of the heating part. The increase in torque pulsation leads to the risk of structural damage during equipment operation, and the noise will also increase accordingly. Summary of the Invention

[0005] Therefore, it is necessary to provide a new type of electrothermal multi-energy flexible magnetic control power generation device that can improve heating power.

[0006] This application provides an electrothermal multi-energy flexible magnetic control power generation device, including: a heating stator, a power generation stator, a rotor, a permanent magnet, and windings;

[0007] The heating stator and the power generating stator are respectively arranged around the rotor, and the heating stator, the power generating stator and the rotor are coaxially arranged, with a gap between the heating stator and the power generating stator along the direction of the coaxial line; the permanent magnet is attached to the surface of the rotor opposite to the heating stator and the surface of the rotor opposite to the power generating stator; the winding is wound on the power generating stator;

[0008] The heating stator includes an outer stator and an inner stator, and the inner stator is located between the outer stator and the rotor;

[0009] The outer stator is made of a different material than the inner stator, wherein the magnetic permeability of the outer stator is greater than a preset magnetic permeability, and the electrical conductivity of the inner stator is greater than a preset electrical conductivity.

[0010] The aforementioned electrothermal multi-energy flexible magnetic control power generation device, by setting a heating stator including an outer stator and an inner stator, with the outer and inner stators respectively arranged around the rotor, and the inner stator located between the outer stator and the rotor, the materials of the outer stator and the inner stator are different. The magnetic permeability of the outer stator is greater than a preset magnetic permeability, and the electrical conductivity of the inner stator is greater than a preset electrical conductivity. This allows the outer stator with high magnetic permeability to establish a magnetic circuit with the permanent magnet, indirectly enhancing the magnetic induction intensity inside the inner stator. The greater the magnetic induction intensity, the greater the eddy current, thereby enhancing the heating power. At the same time, the inner stator with high electrical conductivity further increases the eddy current heating power. In this embodiment, the heating power of the heating stator is significantly improved and the torque pulsation of the heating stator is reduced without slotting or inserting conductor bars. Meanwhile, by arranging the heating stator and the power generation stator along the axial direction, this embodiment of the application achieves effective isolation between the heating part and the power generation part in the thermal field and electromagnetic field, avoiding mutual influence between the heating part and the power generation part, thereby improving the performance of the equipment.

[0011] In one embodiment, the permeability of the outer stator is 2000 to 6000 times the vacuum permeability;

[0012] The conductivity of the inner stator is greater than that of the outer stator.

[0013] In one embodiment, the conductivity of the inner stator is greater than or equal to 20 times the conductivity of the outer stator.

[0014] In one embodiment, the outer stator is made of a ferromagnetic material.

[0015] In one embodiment, the material of the inner stator includes at least one of aluminum and copper.

[0016] In one embodiment, the ratio of the thickness of the outer stator to the thickness of the inner stator is related to both the first difference and the second difference; wherein, the first difference is the difference between the electrical conductivity of the outer stator and the electrical conductivity of the inner stator, and the second difference is the difference between the magnetic permeability of the outer stator and the magnetic permeability of the inner stator.

[0017] In one embodiment, a water tank is provided in the outer stator, and the water tank is arranged around the rotor.

[0018] In one embodiment, the heating stator constitutes the heating part, and the power generating stator and the winding constitute the power generating part;

[0019] Along the direction from the rotor to the heating stator, the thickness of the heating portion is less than the thickness of the power generation portion.

[0020] In one embodiment, the rotor is a hollow cylinder, and the thickness of the rotor is less than the thickness of the power generation section along the direction from the rotor to the power generation stator.

[0021] In one embodiment, there is a gap between the permanent magnet and the heating stator, and there are gaps between the permanent magnet and the power generating stator and the winding.

[0022] In one embodiment, along the direction surrounding the rotor, the N-polar permanent magnet and the S-polar permanent magnet are spaced apart and surface-mounted on the rotor surface, wherein the material of the permanent magnet includes the rare-earth permanent magnet material neodymium iron boron.

[0023] The aforementioned electrothermal multi-energy flexible magnetic control power generation device, by setting a heating stator including an outer stator and an inner stator, with the outer and inner stators respectively arranged around the rotor, and the inner stator located between the outer stator and the rotor, the materials of the outer stator and the inner stator are different. The magnetic permeability of the outer stator is greater than a preset magnetic permeability, and the electrical conductivity of the inner stator is greater than a preset electrical conductivity. This allows the outer stator with high magnetic permeability to establish a magnetic circuit with the permanent magnet, indirectly enhancing the magnetic induction intensity inside the inner stator. The greater the magnetic induction intensity, the greater the eddy current, thereby enhancing the heating power. At the same time, the inner stator with high electrical conductivity further increases the eddy current heating power. In this embodiment, the heating power of the heating stator is significantly improved and the torque pulsation of the heating stator is reduced without slotting or inserting conductor bars. Meanwhile, by arranging the heating stator and the power generation stator along the axial direction, this embodiment of the application achieves effective isolation between the heating part and the power generation part in the thermal field and electromagnetic field, avoiding mutual influence between the heating part and the power generation part, thereby improving the performance of the equipment.

[0041] The electrothermal multi-energy flexible magnetic control power generation equipment integrates power generation and heating functions, converting mechanical energy into electrical energy and electrical energy into heat energy. This enables flexible conversion between multiple energy forms, improving energy utilization efficiency. Specifically, by optimizing topology parameters and magnetic circuit design, the equipment reduces energy loss, improves power generation and heating efficiency, and lowers energy consumption, resulting in significant energy savings. Furthermore, the use of permanent magnets reduces wear-prone components such as brushes and slip rings found in traditional power generation equipment, lowering the failure rate, improving operational reliability and stability, and reducing maintenance costs and downtime. This contributes to the equipment's high reliability.

[0042] The application fields of multi-energy flexible magnetically controlled electrothermal power generation equipment are diverse. For example, in the field of distributed generation, it can be used in homes, commercial buildings, industrial plants, and other locations to provide users with electricity and heat, achieving energy self-sufficiency, reducing dependence on traditional power grids, and improving the security and reliability of energy supply. In the field of smart microgrids, as an important component of smart microgrids, it can be organically combined with other distributed energy sources, energy storage devices, and loads to achieve coordinated operation of source, load, and storage, optimize power resource allocation, and improve the stability and flexibility of microgrids. In the field of renewable energy utilization, it can be combined with renewable energy power generation equipment such as solar and wind power to compensate for the intermittency and instability of renewable energy power generation, achieve energy complementarity and stable supply, and improve the utilization efficiency of renewable energy. In addition, its flexible characteristics make it suitable for some special environments, such as aerospace, marine platforms, and military equipment, providing reliable electricity and heat supply to these fields.

[0043] In one exemplary embodiment, combined with Figures 1a to 3b A flexible magnetically controlled electrothermal power generation device is provided, which includes a heating stator 10, a power generation stator 20, a rotor 30, a permanent magnet 40, and a winding 50.

[0044] The heating stator 10 and the power generation stator 20 are respectively arranged around the rotor 30, and the heating stator 10, the power generation stator 20 and the rotor 30 are coaxially arranged. There is a gap between the heating stator 10 and the power generation stator 20 along the direction of their coaxial axis. Permanent magnets 40 are attached to the surfaces of the rotor 30 opposite to the heating stator 10 and the surfaces of the rotor 30 opposite to the power generation stator 20. The winding 50 is wound on the power generation stator 20. The rotor 30 and the heating stator 10 can constitute the heating part of the equipment, and the rotor 30 and the power generation stator 20 can constitute the power generation part of the equipment. The heating stator 10 can be a three-phase heating stator 10, and the power generation stator 20 can be a three-phase power generation stator 20.

[0045] The heating stator 10 includes an outer stator 11 and an inner stator 12, which are respectively arranged around the rotor 30, with the inner stator 12 located between the outer stator 11 and the rotor 30. The outer stator 11 and the inner stator 12 can be in direct contact. The materials of the outer stator 11 and the inner stator 12 are different. The magnetic permeability of the outer stator 11 is greater than the preset magnetic permeability, and the electrical conductivity of the inner stator 12 is greater than the preset electrical conductivity. That is, the material of the outer stator 11 is a high magnetic permeability material, and the material of the inner stator 12 is a high electrical conductivity material.

[0046] The operation of the aforementioned electrothermal multi-energy flexible magnetic control power generation equipment includes: driven by wind energy or other forms of mechanical energy, the rotor 30 rotates around its axis, causing the permanent magnet 40 mounted on the surface of the rotor 30 to rotate accordingly. The rotation of the permanent magnet 40 generates a periodically changing rotating magnetic field, laying the foundation for subsequent energy conversion. According to the law of electromagnetic induction, the periodically changing rotating magnetic field acts on the winding 50, thereby inducing an electromotive force in the winding 50. When an external circuit is connected to a load to form a closed loop, current flows, realizing electrical energy output. At the same time, also based on the law of electromagnetic induction, the periodically changing rotating magnetic field induces eddy current effects in the inner stator 12 of the heating stator 10, forming an eddy current loop and generating heat. This principle causes the heating stator 10 to generate a large amount of thermal energy. Through the above two parallel processes, this equipment realizes the synchronous conversion and output of mechanical energy into electrical energy and thermal energy.

[0047] In this embodiment, the heating stator 10 includes an outer stator 11 and an inner stator 12. The outer stator 11 is made of a high magnetic permeability material, while the inner stator 12 is made of a high electrical conductivity material. That is, the outer stator 11 focuses more on high magnetic permeability, while the inner stator 12 focuses more on high electrical conductivity. Thus, the outer stator 11, which has high magnetic permeability, can establish a magnetic circuit with the permanent magnet 40, indirectly enhancing the magnetic induction intensity inside the inner stator 12. The greater the magnetic induction intensity, the greater the eddy current, thereby enhancing the heating power of the heating stator 10. At the same time, the inner stator 12, which has high electrical conductivity, will further improve the eddy current heating power. In this embodiment, without slotting or inserting conductor bars, the outer stator 11 and the inner stator 12 work together through the concept of composite materials to significantly improve the heating power of the heating stator 10 and reduce the torque pulsation of the heating stator 10. Meanwhile, by arranging the heating stator 10 and the power generation stator 20 along the axial direction, the embodiments of this application can effectively decouple the heating part and the power generation part in terms of electromagnetics and heat, thereby achieving effective isolation between the heating part and the power generation part in terms of thermal field and electromagnetic field, avoiding mutual interference between the heating part and the power generation part, and thus improving the performance of the equipment.

[0048] The generator stator 20 is made of silicon steel sheets. The material properties of silicon steel effectively suppress eddy current losses, so it can be approximated that the generator stator 20 does not generate heat during operation, and the eddy current effect is mainly concentrated inside the inner stator 12. Furthermore, the external output power of this equipment consists of both electrical power and thermal power. The output power is mainly affected by the mechanical speed and torque (electromagnetic torque on the generator side, torque on the heating side). By actively adjusting the electromagnetic torque on the generator side, adaptive adjustment of the speed and torque on the heating side can be achieved. Electrical power and thermal power can be converted between each other within a certain range to meet the output requirements under different operating conditions, achieving flexible power output. During the equipment design process, the structural parameters of the heating part and the generator part can also be designed independently, ensuring independent and effective control of each part during equipment operation.

[0049] In an exemplary embodiment, the permeability of the outer stator 11 is 2000 to 6000 times that of vacuum permeability, and the conductivity of the inner stator 12 is much greater than that of the outer stator 11. This allows the magnetic induction intensity inside the inner stator 12 to be enhanced, and the eddy currents inside the inner stator 12 to be increased. The superposition and cooperation of these two mechanisms greatly improves the heating power of the heating stator 10, while eliminating the need for slotting and inserting guide bars, thereby ensuring the mechanical strength of the heating stator 10 and reducing the torque pulsation of the heating stator 10.

[0050] Optionally, the conductivity of the inner stator 12 is greater than that of the outer stator 11, for example, the conductivity of the inner stator 12 is at least 20 times that of the outer stator 11.

[0051] In this embodiment, the outer stator 11, which has high magnetic permeability, can establish a magnetic circuit with the permanent magnet 40, indirectly enhancing the magnetic induction intensity inside the inner stator 12. The greater the magnetic induction intensity, the greater the eddy current, thereby enhancing the heating power of the heating stator 10. At the same time, the inner stator 12, which has high conductivity, will further improve the eddy current heating power. In this embodiment, without slotting or inserting conductor bars, the outer stator 11 and the inner stator 12 cooperate through the concept of composite anisotropic materials, which greatly improves the heating power of the heating stator 10 and reduces the torque pulsation of the heating stator 10.

[0052] Meanwhile, by arranging the heating stator 10 and the power generation stator 20 along the axial direction, this embodiment effectively decouples the heating and power generation components electromagnetically and thermally. This achieves effective isolation between the heating and power generation components in both thermal and electromagnetic fields, preventing mutual interference and thus improving equipment performance. Furthermore, this structure increases the component density within a limited space, enhancing the device's power density and making it suitable for applications with high power density requirements.

[0053] Optionally, the material of the outer stator 11 may include ferromagnetic materials, such as low-carbon steel, for example, national standard No. 10 steel.

[0054] In this embodiment, the outer stator 11 with high magnetic permeability can establish a magnetic circuit with the permanent magnet 40, indirectly enhancing the magnetic induction intensity inside the inner stator 12. The greater the magnetic induction intensity, the greater the eddy current, thereby enhancing the heating power of the heating stator 10. At the same time, the material of the outer stator 11, including low carbon steel, makes the outer stator 11 low in cost and easy to implement.

[0055] Optionally, the inner stator 12 may be made of at least one of aluminum and copper.

[0056] In this embodiment, not only can the outer stator 11 enhance the heating power of the heating stator 10, but the inner stator 12 with high conductivity will further improve the eddy current heating power, thereby further enhancing the heating power of the heating stator 10. At the same time, the material of the inner stator 12 includes at least one of aluminum and copper, making the inner stator 12 low in cost and easy to implement.

[0057] In an exemplary embodiment, the ratio of the thickness of the outer stator 11 to the thickness of the inner stator 12 is related to both the first difference and the second difference; wherein, the first difference is the difference between the electrical conductivity of the outer stator 11 and the electrical conductivity of the inner stator 12, and the second difference is the difference between the magnetic permeability of the outer stator 11 and the magnetic permeability of the inner stator 12. The ratio of the thickness of the outer stator 11 to the thickness of the inner stator 12 is, for example, the optimal ratio of the thickness of the outer stator 11 to the thickness of the inner stator 12, that is, the ratio that can guarantee the optimal performance of the electrothermal multi-energy flexible magnetic control power generation device. In other words, the optimal ratio of the thickness of the outer stator 11 to the thickness of the inner stator 12 can be adjusted according to the difference between the conductivity of the outer stator 11 and the conductivity of the inner stator 12, as well as the difference between the magnetic permeability of the outer stator 11 and the magnetic permeability of the inner stator 12, to ensure that the magnetic induction intensity inside the inner stator 12 is sufficiently enhanced, thereby enhancing the heating power. At the same time, it makes the thickness of the outer stator 11 and the thickness of the inner stator 12 more easily adaptable to the thickness required in actual application scenarios.

[0058] In one exemplary embodiment, reference is made to Figure 3a The outer stator 11 is provided with a water tank, which surrounds the rotor 30. The water tank can hold water, and the heat generated by the inner stator 12 is provided to the heat demand point through the water in the water tank. That is, the water in the water tank serves as the heat output medium of the heating stator 10.

[0059] In this embodiment, the heat generated by the heating stator 10 can be efficiently collected by a matching collection device to meet various heat load requirements. Furthermore, the collected heat energy can be converted into electrical energy through thermoelectric conversion technology to support the power grid. If the quality of the collected heat energy cannot meet specific usage requirements, it can be treated by secondary heating to improve the heat energy quality and adapt to different application scenarios.

[0060] In one exemplary embodiment, the heating stator 10 constitutes the heating part, and the power generation stator 20 and winding 50 constitute the power generation part; along the direction of the rotor 30 pointing towards the heating stator 10, the thickness of the heating part is less than the thickness of the power generation part; optionally, the rotor 30 has a hollow cylinder structure, and along the direction of the rotor 30 pointing towards the power generation stator 20, the thickness of the rotor 30 is less than the thickness of the power generation part; optionally, the thickness of the rotor 30 is similar to the thickness of the heating part. In other embodiments, the rotor 30 may also have a solid cylinder structure. The specific structure of the rotor 30 can be flexibly set according to the needs of the actual application scenario to ensure the high reliability of the electrothermal multi-energy flexible magnetic control power generation device in achieving flexible conversion of multiple energy forms. This application embodiment does not limit this.

[0061] In this embodiment, the rotor 30 can be made of various materials, as long as the high reliability of the electrothermal multi-energy flexible magnetic control power generation device can achieve flexible conversion of multiple energy forms is ensured. Optionally, the rotor 30 can be made of iron, which makes the rotor 30 low in cost and easy to implement.

[0062] In an exemplary embodiment, there is a gap between the permanent magnet 40 and the heating stator 10, and there is a gap between the permanent magnet 40 and the power generation stator 20 and the winding 50. The specific size of the gap can be flexibly set according to the needs of the actual application scenario, so as to ensure the high reliability of the electrothermal multi-energy flexible magnetic control power generation equipment to achieve flexible conversion of multiple energy forms.

[0063] In an exemplary embodiment, along the direction surrounding the rotor 30, N-polar permanent magnets 40 and S-polar permanent magnets 40 are spaced and surface-mounted on the surface of the rotor 30. The permanent magnets 40 are made of rare-earth permanent magnet material neodymium iron boron. This not only ensures the reliable realization of the working magnetic field of the electrothermal multi-energy flexible magnetic control power generation device, but also makes the permanent magnets 40 low-cost and easy to implement.

[0064] In one exemplary embodiment, the electrothermal multi-energy flexible magnetic control power generation device further includes a housing. The heating stator 10, the power generation stator 20, the rotor 30, the permanent magnet 40, and the winding 50 are all disposed within the housing. The housing protects the internal components and insulates them from the external environment. Optionally, the housing can be made of aluminum to reduce cost and facilitate implementation.

[0065] To verify the device's ability to simultaneously output electrical and thermal energy, a simplified simulation model was built using finite element analysis. The simulation parameters are shown in Table 1. In the simulation, rotor 30 was operated at its rated speed of 600 r / min, winding 50 was connected in a three-phase star configuration, and the load was set as a resistive-inductive load with a resistance of 31.02 ohms and an inductance of 32.47 mH. The inner stator 12 of the heating stator 10 is made of aluminum, and the outer stator 11 is made of No. 10 steel.

[0066] The output voltage and current waveforms of the device are as follows: Figure 4 and Figure 5 As shown in the figure, the device can effectively output electrical energy. In this embodiment, the device outputs 4150W of power.
