[0028] Figure 2 This is a schematic diagram of the circuit structure of the intelligent electric control cabinet of the present utility model; DETAILED DESCRIPTION

[0029] The following will be combined with the Figure 1 To the attached Figure 2The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] Traditional data center power supply systems are connected to the power grid through independent power supply systems. On the power consumption side, a corresponding control system monitors the different power supply systems. When a failure occurs, the control system automatically identifies and switches the power supply to maintain uninterrupted power supply. This data center power supply system typically connects to the grid independently, rather than centrally managed. This results in a decentralized system that is not conducive to unified management and also presents layout issues.

[0031] To this end, the applicant proposed an intelligent electric control cabinet for energy storage and power generation, the purpose of which is to enable multiple different power supply terminals to access power at a unified node through the intelligent electric control cabinet, thereby facilitating the power supply and discharge management of the uninterruptible power supply.

[0032] Combine Figure 1 The present invention proposes an intelligent electric control cabinet for energy storage and power generation, which is configured to have a cabinet body 10, and the cabinet body 10 has an accommodating space. The accommodating space is used to accommodate various functional modules.

[0033] It should be understood that in this embodiment, the cabinet body 10 is the core of the entire intelligent electric control cabinet, and various functional modules are arranged inside, and unified design facilitates unified management.

[0034] The cabinet 10 may preferably have a vertical cubic structure or a horizontal cubic structure, but is not limited thereto and any suitable shape design may be used.

[0035] Since the cabinet 10 needs to accommodate various electronic control function modules, it should have sufficient strength to ensure that it always maintains good mechanical properties during operation. Preferably, the cabinet 10 can be made of metal materials, such as aluminum alloy, steel or iron.

[0036] like Figure 2 The figure shows a schematic diagram of the basic functional modules of an intelligent electric control cabinet. Specifically, the intelligent electric control cabinet includes a mains power access device 20, a green energy power access device 30, a power generation device 40, an uninterruptible power supply 50, a power storage device 60, and an electronic control device 70. These functional modules can each perform their respective functions and, when combined, form an uninterruptible power supply system.

[0037] Specifically, the mains power access device 20, green energy power access device 30, uninterruptible power supply 50, power storage device 60 and electric control device 70 are located in the accommodation space, which is beneficial for the cabinet 10 to protect and support these functional modules.

[0038] It should be noted that in some embodiments, the generator 40 is located within the accommodating space or outside the cabinet 10. Furthermore, the generator 40 can be integrated into the cabinet 10, thus forming a single, integrated structure. This design can be used, for example, in situations where the intelligent electrical control cabinet is placed outside and noise requirements are low. However, in some situations, such as indoors, where sound requirements are high, locating the generator 40 inside the cabinet 10 is not appropriate. In such scenarios, the generator 40 is placed inside the cabinet 10. Electrical connections can then be established using corresponding wiring. For example, the cabinet 10 can be placed indoors, while the generator 40 is placed outdoors or elsewhere far away from the cabinet 10 to reduce the impact of noise on the location of the cabinet 10. It should be noted that in this embodiment, the generator 40 is, for example, a gasoline or diesel generator.

[0039] The mains power access device 20, the green energy power access device 30, and the power generation device 40 are each connected to a collector line 90. That is, the power supply for the entire power supply cabinet includes at least three inputs: the mains power access device 20, the green energy power access device 30, and the power generation device 40, ensuring the power demand of the entire power supply cabinet.

[0040] The mains access device 20 is used to access the mains. Generally, the mains is supplied by the power grid. In actual use, it is only necessary to connect the input point of the mains power grid to the mains access device 20.

[0041] The mains access device 20 is a power access socket, that is, provided with corresponding interfaces, and connected to the mains power grid through these interfaces. Of course, when specifically connected, the mains access device 20 is connected to the collector line 90 through a second grid-connected switch 201.

[0042] The green energy power supply access device 30 is also connected to the collector line 90. The function of the green energy power supply access device 30 is the same as that of the mains power access device 20, and it is also a wiring device. Specifically, the second power supply device 30 is used to connect to an external power supply device to realize power supply processing.

[0043] In detail, in a specific embodiment, the green energy power supply access device 30 includes a first power supply access component 301 for plugging into the power output end of a photovoltaic power generation device and a second power supply access component 302 for plugging into the power output end of a wind power generation device, which are independent of each other; the first power supply access component 301 is connected to the collector line through an inverter control mechanism 303; the second power supply access component 302 is connected to the collector line through a conversion control mechanism 304.

[0044] Green energy supply is a major energy advantage of my country, which can reduce costs for enterprises. Therefore, this embodiment can access two green energy routes: photovoltaic power supply and wind power generation.

[0045] The first power supply access component 301 realizes photovoltaic power generation access. Generally, photovoltaic power generation is very common nowadays, and there are corresponding photovoltaic power generation devices in many power grids. According to traditional practices, photovoltaic power generation devices can only be used directly on power-consuming equipment or incorporated into the existing power grid before they can be used by data centers. Therefore, for users, this solution is very convenient, that is, the power output end of photovoltaic power generation can be directly connected to the terminal of the first power supply point component 301. The power is directly connected to the collector after conversion by the inverter control mechanism 303 of the first power supply access component 301. It should be understood that the inverter control mechanism 303 is implemented using an existing photovoltaic power generation inverter circuit, such as a DC / AC conversion circuit. That is, in this embodiment, the first power supply access component 301 includes a terminal and an inverter control mechanism 303. The terminal is connected to the inverter control mechanism 303 through an electric wire, and the inverter control mechanism 303 is connected to the collector.

[0046] Similarly, the power input from the wind power generation device is achieved through the second power supply access component 302. It should be understood that the wind power generation device can be a power generation device provided by the user end. It should also be clear that for many existing electricity users, there are some wind power generation devices themselves. Therefore, this embodiment can well achieve coordinated access to the existing power supply network by setting up the second power supply access component 302. Of course, it should be clear that the second power supply access component 302 is mainly used to achieve circuit access with the wind power generation power supply end and to be connected to the collector line 90. The second power supply access component 302 includes corresponding terminals and a conversion control mechanism 304. The corresponding terminals are electrically connected to the conversion control mechanism 304 via wires, and are ultimately connected to the collector line by the conversion control mechanism 304. Of course, the conversion control mechanism 304 can be implemented using an existing wind power generation conversion circuit, such as an AC / DC / AC circuit.

[0047] It should be noted that compared with the traditional power distribution system, this technology reserves ports for access to wind power generation and photovoltaic power generation through the first power supply access component 301 and the second power supply access component 302, and is particularly suitable for direct access to existing wind power generation and photovoltaic power generation at the power consumption end through this power supply cabinet.

[0048] In a specific embodiment, the intelligent electric control cabinet further includes a photovoltaic power generation device (not shown) mounted on the top of the cabinet 10. The power output of the photovoltaic power generation device is plugged into the input interface of the first power access component 301. In other words, the photovoltaic panel can be directly mounted on the top of the cabinet 10 and then connected directly to the terminal posts of the first power access component 301 via wires. This method is very simple and quick to use.

[0049] In one specific embodiment, the power generation device 40 is a diesel or gasoline generator, electrically connected to the collector line via a first grid-connected switch 401. In other words, in this embodiment, the power supply cabinet self-generates electricity to meet its power needs through the power generation device 40. It should be understood that in extreme situations where the external power supply is interrupted, the power generation device 40 can still meet the power supply needs.

[0050] In this solution, the collector is connected to the input end of the uninterruptible power supply 50, and the uninterruptible power supply 50 has at least two first outputs, one of which is connected to the power storage device 60 to charge the power storage device 60, and the remaining at least one first output is used to supply power to the load.

[0051] Importantly, in this embodiment, the entire power supply cabinet transmits power to the load via an uninterruptible power supply (UPS) 50. The utility power and green energy power supply access device 30 do not directly power the load. Furthermore, when sufficient power is available, the UPS 50 can charge the power storage device 60, creating a power reserve and enhancing emergency response capabilities in the event of a power failure.

[0052] In addition, the energy storage device 60 has at least two secondary outputs, one of which is connected to an input of the uninterruptible power supply 50 to provide reverse power to the uninterruptible power supply 50. Specifically, one output of the energy storage device 60 is used to provide reverse power to the uninterruptible power supply 50. When the power grid is unstable, the energy storage device 60 can transfer stored power to the uninterruptible power supply 50. Furthermore, the energy storage device 60 has other secondary outputs, such as an external power supply interface, which can ensure the use of external powered devices, such as lighting.

[0053] Preferably, in a specific implementation, the power storage device 60 includes a power storage battery, and the power storage battery is a lithium iron phosphate blade battery.

[0054] The electronic control device 70 is electrically connected to the mains power access device 20, the green energy power access device 30, the generator 40, and the uninterruptible power supply 50, respectively, and is used to control the power supply execution of the mains power access device 20, the green energy power access device 30, the generator 40, and the output of the uninterruptible power supply 50 based on the status information of the mains power access device 20, the green energy power access device 30, the generator 40, and the uninterruptible power supply 50. The electronic control device 70 serves as the power distribution control terminal for the entire intelligent electric control cabinet. Specifically, under normal circumstances, the uninterruptible power supply 50 is powered by wind power and / or photovoltaic power generation. However, when wind power and photovoltaic power generation cannot meet the demand, the electronic control device 70 can detect this condition and control the connection to the mains power supply. Furthermore, when the mains power cannot meet the power demand, the electronic control device 70 controls the generator 40 to generate electricity to provide power. It should be understood that the electronic control device 70 of this embodiment can be implemented using existing control technologies. Specifically, the electronic control device 70 can identify and control input switching based on the three power sources: the mains power supply, the green energy supply, and the generator, achieving the most economical power consumption while ensuring safe and continuous power supply. For example, if the green energy supply is interrupted, the electronic control device 70 can identify and switch to the mains power supply, thereby ensuring continuous power supply. Furthermore, if the mains power supply fails, power is switched to the generator 40. The specific switching structure can be implemented using existing technologies and will not be detailed here.

[0055] In summary, the technical solution of the present invention integrates the mains power access device 20, the green energy power supply access device 30, and the power generation device 40, especially the green energy power supply access device 30 as a standard access structure, which can be combined with the mains power access device 20 and the power generation device 40 to form a multi-channel input, which can meet the power supply needs of the power consumption system, especially solving the problem of the dispersion of various power supply systems in the existing technology; at the same time, it solves the problem of multi-channel power supply and ensures the continuous power supply of the power consumption system.

[0056] Additionally, in other embodiments, Figure 1 As shown, the corresponding input interfaces of the mains power access device 20 and the green energy power access device 30 are exposed outside the cabinet 10. That is, the mains power access device 20 and the green energy power access device 30 are exposed, which ensures convenience during use, that is, they can be directly plugged in outside the cabinet 10.

[0057] More preferably, in order to protect the mains power access device 20 and the green energy power supply access device 30, a groove 102 is provided in the cabinet 10, and the corresponding input end interfaces of the mains power access device 20 and the green energy power supply access device 30 are located in the groove 102, and a protective cover 103 that can be opened and closed is provided at the opening of the groove 102 to enclose the corresponding input end interfaces of the mains power access device 20 and the green energy power supply access device 30. The protective cover 103 and the cabinet 10 can be pivotally connected together. When closed, the protective cover 103 can close the groove 102, so as to prevent impurities and the like from falling into the groove 102, thereby ensuring the effective use of the mains power access device 20 and the green energy power supply access device 30. In another specific embodiment, the mains power access device 20 and the green energy power supply access device 30 are arranged in different grooves, which is convenient for distinction and wiring, and avoids interference between them.

[0058] Finally, another aspect of the present invention provides a power system comprising a power receiving device and the aforementioned energy storage and power generation intelligent electric control cabinet. At least one remaining first output of the uninterruptible power supply 50 of the intelligent electric control cabinet is electrically connected to the power receiving device for powering. The power receiving device is a data storage center and / or a municipal computer system. The use of such technology ensures convenient power supply to the data center or municipal computer system. Of course, it should be noted that the energy storage and power generation intelligent electric control cabinet is particularly suitable for applications requiring continuous power supply, such as supercomputers, switches, information equipment, and the like, which require uninterrupted power supply.

[0059] Based on the disclosure and teachings of the above description, those skilled in the art may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and any modifications and variations of the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although certain specific terms are used in this description, these terms are for convenience of description only and do not constitute any limitation to the present invention.
