Description

Technical Field

[0001] The utility model relates to the technical field of UPS power supplies, and particularly relates to a flywheel energy storage UPS power supply system. Background Art

[0002] In many areas, the mains power supply may be affected by natural disasters, equipment failures, grid maintenance and other factors, resulting in unstable power supply, power outages or voltage fluctuations. This instability poses a serious threat to critical facilities that require continuous power supply, such as data centers, medical equipment, communication base stations, etc. Summary of the Invention

[0003] The purpose of the utility model is to provide a flywheel energy storage UPS power supply system that can improve the continuity of power supply and achieve seamless switching of load power supply and long-term backup guarantee.

[0004] A flywheel energy storage UPS power supply system includes a mains input circuit, an ATS switch, a UPS main cabinet and a diesel generator. The mains input circuit is connected to the ATS switch, the ATS switch is connected to the UPS main cabinet, the UPS main cabinet is also connected with a magnetic levitation flywheel module, and the diesel generator is connected to the ATS switch;

[0005] The UPS main cabinet includes a first switch, a rectifier module, an inverter module, a first static switch and a second switch. One end of the first switch is connected to the ATS switch, the other end of the first switch is connected to the rectifier module, the rectifier module is connected to one end of the inverter module, the other end of the inverter module is connected to one end of the first static switch, the other end of the first static switch is connected to the first end of the second switch, and the magnetic levitation flywheel module is connected between the rectifier module and the inverter module.

[0006] In the above solution, when the city has normal power supply, the first switch and the second switch are closed, and the mains power passes through the ATS switch and is output to the UPS main cabinet. The rectifier module converts alternating current into direct current. Since the magnetic levitation flywheel module is connected between the rectifier module and the inverter module, the converted direct current enters the magnetic levitation flywheel module for storage. The inverter module converts the direct current into alternating current, and the alternating current passes through the static switch and the second switch and is output, providing high-quality power for the load and being able to store electrical energy at the same time. When the mains power fails or is interrupted, the magnetic levitation flywheel module releases energy to achieve continuous power supply for the load. When the system detects a mains power outage or failure, while the magnetic levitation flywheel module releases energy, the diesel generator can be started and supplied to the UPS main cabinet through the ATS switch to keep the UPS main cabinet in load output, realizing seamless switching of load power supply and long-term backup guarantee.

[0007] Further, the UPS main cabinet further includes a third switch and a second static switch. One end of the third switch is connected to the ATS transfer switch, the other end of the third switch is connected to the second static switch, and the other end of the second static switch is connected between the first static switch and the second switch.

[0008] In the above solution, when the mains power fails or malfunctions, the first switch disconnects and the third switch closes. In this way, the electric energy of the diesel generator can be output to the third switch and the second static switch through the ATS transfer switch. By introducing the third switch and the second static switch, the system has more control paths during power switching. This allows the system to manage the power flow more flexibly under different power states and requirements, ensuring the continuity and stability of power supply.

[0009] Further, the UPS main cabinet further includes a fourth switch. One end of the fourth switch is connected to the ATS transfer switch, and the other end of the fourth switch is connected to the second end of the second switch.

[0010] In the above solution, in the power system, the additional switch can serve as a redundant path. When the main path fails, the system can switch to the backup path through the fourth switch, thereby improving the reliability and fault tolerance of the entire system.

[0011] Further, the magnetic levitation flywheel module includes a power converter and a magnetic levitation flywheel. One end of the power converter is connected between the rectifier module and the inverter module, and the other end of the power converter is connected to the magnetic levitation flywheel.

[0012] In the above solution, the power converter is responsible for converting the direct current output by the rectifier module into a form suitable for storage by the magnetic levitation flywheel, and at the same time converting the stored energy back into direct current to supply the inverter module when needed. Such a design improves the efficiency of electric energy conversion and reduces energy loss; when there is external mains power supply, the flywheel can continuously rotate in a vacuum environment to store energy in the form of kinetic energy. The magnetic levitation flywheel can store and release energy in an extremely short time, which enables the system to quickly respond to the instantaneous demand of the power grid or power supply interruption and provide instant backup power for the load.

[0013] Further, one end of the power converter is connected to one end of a fifth switch. The fifth switch is installed in the magnetic levitation flywheel module. The other end of the fifth switch is connected to one end of a sixth switch, and the other end of the sixth switch is connected between the rectifier module and the inverter module.

[0014] In the above solution, the addition of the fifth switch and the sixth switch can accelerate the system's response speed to power state changes. In the event of a mains power outage or other power anomalies, the system can quickly switch to the flywheel energy storage system through these switches to maintain uninterrupted power supply; the configuration of the fifth switch and the sixth switch enables the power converter to more effectively store the DC electrical energy of the rectifier module in the maglev flywheel and release the energy back to the system when needed, thus optimizing the energy storage and release process.

[0015] A flywheel energy storage UPS power system of the present utility model has the beneficial effects of being able to improve power supply continuity, achieving seamless switching of load power supply and long-term backup guarantee. When the city has normal power supply, the first switch and the second switch are closed, and the mains power passes through the ATS switch and is output to the UPS main cabinet. The rectifier module converts the alternating current into direct current. Since the maglev flywheel module is connected between the rectifier module and the inverter module, the converted direct current enters the maglev flywheel module for storage. The inverter module converts the direct current into alternating current, and the alternating current passes through the static switch and the second switch and is output to provide high-quality power for the load, and at the same time, the electrical energy can be stored. When the mains power fails or is interrupted, the maglev flywheel module releases the energy to achieve continuous power supply for the load. When the system detects a mains power outage or a fault, while the maglev flywheel module releases energy, it can start the diesel generator and supply it to the UPS main cabinet through the ATS switch to keep the UPS main cabinet with load output, achieving seamless switching of load power supply and long-term backup guarantee.

Detailed Embodiment

[0018] Hereinafter, a flywheel energy storage UPS power system of the present utility model will be further described in detail in conjunction with specific embodiments and the drawings.

[0019] As Figure 1As shown, in a preferred embodiment, a flywheel energy storage UPS power supply system of the present utility model includes a mains input circuit 1, an ATS switch 2, a UPS main cabinet 3, and a diesel generator 5. The mains input circuit 1 is connected to the ATS switch 2, the ATS switch 2 is connected to the UPS main cabinet 3, the UPS main cabinet 3 is further connected to a magnetic levitation flywheel module 4, and the diesel generator 5 is connected to the ATS switch 2.

[0020] The UPS main cabinet 3 includes a first switch 6, a rectifier module 7, an inverter module 8, a first static switch 9, and a second switch 10. One end of the first switch 6 is connected to the ATS switch 2, the other end of the first switch 6 is connected to the rectifier module 7, the rectifier module 7 is connected to one end of the inverter module 8, the other end of the inverter module 8 is connected to one end of the first static switch 9, the other end of the first static switch 9 is connected to the first end of the second switch 10, and the magnetic levitation flywheel module 4 is connected between the rectifier module 7 and the inverter module 8.

[0021] In the above embodiment, when the city is normally powered, the first switch 6 and the second switch 10 are closed. The mains power is output to the UPS main cabinet 3 through the ATS switch 2. The rectifier module 7 converts the alternating current into direct current. Since the magnetic levitation flywheel module 4 is connected between the rectifier module 7 and the inverter module 8, the converted direct current enters the magnetic levitation flywheel module 4 for storage. The inverter module 8 converts the direct current into alternating current, and the alternating current is output through the static switch and the second switch 10, providing high-quality power for the load and being able to store electrical energy at the same time. When the mains power fails or is interrupted, the magnetic levitation flywheel module 4 releases the energy to realize continuous power supply for the load. When the system detects a mains power outage or fault, while the magnetic levitation flywheel module 4 releases energy, the diesel generator 5 can be started and supplied to the UPS main cabinet 3 through the ATS switch 2 to keep the UPS main cabinet 3 outputting with load, realizing seamless switching of load power supply and long-time backup guarantee.

[0022] As Figure 1 shown, in some embodiments, the UPS main cabinet 3 further includes a third switch 11 and a second static switch 12. One end of the third switch 11 is connected to the ATS switch 2, the other end of the third switch 11 is connected to the second static switch 12, and the other end of the second static switch 12 is connected between the first static switch 9 and the second switch 10. When the mains power fails or is interrupted, the first switch 6 is disconnected and the third switch 11 is closed. In this way, the electrical energy of the diesel generator 5 can be output to the third switch 11 and the second static switch 12 through the ATS switch 2. By introducing the third switch 11 and the second static switch 12, the system has more control paths during power switching. This allows the system to more flexibly manage the power flow under different power states and demands, ensuring the continuity and stability of power supply.

[0023] As Figure 1 shown, in some embodiments, the UPS main cabinet 3 further includes a fourth switch 13. One end of the fourth switch 13 is connected to the ATS switch 2, and the other end of the fourth switch 13 is connected to the second end of the second switch 10. In the power system, the additional switch can serve as a redundant path. When the main path fails, the system can switch to the backup path through the fourth switch 13, thereby improving the reliability and fault tolerance of the entire system.

[0024] As Figure 1 shown, in some embodiments, the magnetic levitation flywheel module 4 includes a power converter 41 and a magnetic levitation flywheel 42. One end of the power converter 41 is connected between the rectifier module 7 and the inverter module 8, and the other end of the power converter 41 is connected to the magnetic levitation flywheel 42. The power converter 41 is responsible for converting the direct current output by the rectifier module 7 into a form suitable for storage in the magnetic levitation flywheel 42, and at the same time converting the stored energy back into direct current to supply the inverter module 8 when needed. This design improves the efficiency of power conversion and reduces energy loss; when there is external mains power supply, the flywheel can continuously rotate in a vacuum environment to store energy in the form of kinetic energy. The magnetic levitation flywheel 42 can store and release energy in an extremely short time, enabling the system to quickly respond to the instantaneous demand or power supply interruption of the power grid and provide immediate backup power for the load.

[0025] As Figure 1 shown, in some embodiments, one end of the power converter 41 is connected to one end of a fifth switch 14. The fifth switch 14 is installed in the magnetic levitation flywheel module 4. The other end of the fifth switch 14 is connected to one end of a sixth switch 15, and the other end of the sixth switch 15 is connected between the rectifier module 7 and the inverter module 8. The addition of the fifth switch 14 and the sixth switch 15 can accelerate the system's response speed to changes in the power supply state. In the event of a mains power interruption or other power anomalies, the system can quickly switch to the flywheel energy storage system through these switches to maintain uninterrupted power supply; the configuration of the fifth switch 14 and the sixth switch 15 enables the power converter 41 to more effectively store the DC electrical energy of the rectifier module 7 in the magnetic levitation flywheel 42 and release the energy back to the system when needed, thereby optimizing the energy storage and release process.

[0026] The working principle and process of a flywheel energy storage UPS power system of the present utility model are as follows: When the city is normally powered, the first switch 6 and the second switch 10 are closed. The mains power passes through the ATS switch 2 and is output to the UPS main cabinet 3. The rectifier module 7 converts the alternating current into direct current. Since the magnetic levitation flywheel module 4 is connected between the rectifier module 7 and the inverter module 8, the converted direct current enters the magnetic levitation flywheel module 4 for storage. The inverter module 8 converts the direct current into alternating current, and the alternating current is output after passing through the static switch and the second switch 10. When the mains power fails or is interrupted, the magnetic levitation flywheel module 4 releases energy to achieve continuous power supply to the load. When the system detects a power outage or a fault in the mains power, while the magnetic levitation flywheel module 4 releases energy, the diesel generator 5 can be started and supplied to the UPS main cabinet 3 through the ATS switch 2 to keep the UPS main cabinet 3 outputting with a load.
