[0038] Figure 1 FIG. 1 shows a schematic diagram of a data center power supply system structure according to an embodiment of the present application. Figure 1 The data center power supply system includes a power supply module 100, a first power generation device 200, a second power generation device 300, an energy storage module 400, a control module 500, and a switching module 600; the power supply module 100 is used to access the mains to supply power to the data center load; the first power generation device 200 is connected to the energy storage module 400, and the first power generation device 200 is used to charge the energy storage module 400; the energy storage module 400 and the second power generation device 300 are connected to the switching module 600, and supply power to the data center load under the control of the switching module 600; the control module 500 is connected to the switching module 600, and the control module 500 is used to control the operation of the switching module 600.

[0039] In some embodiments, when the mains power is normal, the power supply system supplies power to the data center load (for example, refrigeration equipment, servers, fresh air equipment, lighting systems and other electrical equipment in the data center) by the power supply module 100 connected to the mains power. The first power generation device 200 can charge the energy storage module 400. When the mains power is cut off, the power supply system can control the switching module 600 through the control module 500 to switch to the energy storage module 400 and / or the second power generation device 300 to supply power to the data center load. Ensure the stable operation of the data center load and reduce the losses caused by unstable mains power supply.

[0040] In some embodiments, the power supply module 100 includes but is not limited to power distribution equipment such as transformers and power distribution cabinets. The power supply module 100 adjusts the city power to a voltage level suitable for each load in the data center and transmits it to the loads in the data center for use.

[0041] In some embodiments, the data center power supply system further includes a power supply detection module 800, and the power supply detection module 800 is respectively connected to the power supply module 100 and the control module 500. The power supply detection module 800 is used to detect the operating status of the power supply module 100 in real time, so that the control module 500 can make corresponding responses based on the operating status of the power supply module 100. For example, when the power supply module 100 is powered off or unstable in operation, the control module 500 can switch the energy storage module 400 and / or the second power generation device 300 through the switching module 600 to supply power to the data center load; the control module 500 can also issue an alarm to remind the corresponding operation and maintenance personnel to perform maintenance.

[0042] In some embodiments, the power supply detection module 800 includes, but is not limited to, sensors for measuring power system parameters such as voltage, current, power, temperature, etc. (e.g., current sensor, voltage sensor, power sensor, temperature sensor, electric field sensor, etc.), one-way / two-way electric energy meter and data acquisition device. The data acquisition device can obtain the operation status and electric energy consumption of the power supply module from the sensor and the electric energy meter, and transmit the obtained information to the control module 500 based on the wired / wireless communication connection established with the control module 500.

[0043] In some embodiments, the control module 500 includes but is not limited to various controllers that can be used for input, output, execution of logic judgment and control commands. To facilitate users to view information and operate, the control module 500 may also include a display.

[0044] In some embodiments, the first power generation device 200 includes a photovoltaic power generation component and / or a wind power generation component. For example, the first power generation device 200 may include a number of solar panels and / or a number of wind turbines. In some embodiments, the first power generation device 200 may also include biomass power generation equipment, tidal power generation equipment or waste heat power generation equipment (for example, a generator using Organic Rankine Cycle (ORC) technology, etc.). In some embodiments, the second power generation device 300 is used as a temporary or emergency power generation device when the city power is out or the energy storage module 400 is insufficient. The second power generation device 300 may include a diesel generator, etc. Here, those skilled in the art can arbitrarily set the first power generation device 200 and the second power generation device 300 based on the actual situation of the data center.

[0045] In some embodiments, the data center power supply system further includes a voltage stabilizing module 700, and the first power generation device 200 charges the energy storage module 400 via the voltage stabilizing module 700. The voltage stabilizing module 700 is used to convert the unstable voltage output by the first power generation device 200 into a stable preset voltage to ensure the stability and safety of charging the energy storage module 400. The voltage stabilizing module 700 may be a DC-DC converter. For example, when a photovoltaic power generation device is used to charge an energy storage module, the direct current generated by the photovoltaic power generation device may fluctuate due to the influence of light intensity or temperature. Directly using such unstable electricity for charging may cause damage to the energy storage module. At this time, the voltage stabilizing module can be used to convert the unstable voltage output by the photovoltaic power generation device into a stable voltage before charging.

[0046] In some embodiments, the energy storage module 400 includes an energy storage device 401 and a battery management module 402. The energy storage device 401 can be set by a person skilled in the art based on the charging / power supply requirements of the data center. It can be any form such as a lithium-ion battery, a lead-acid battery or a flow battery, which is not limited here. The battery management module 402 is connected to the energy storage device 401 to monitor and manage the state of the energy storage device 401, prevent the energy storage device 401 from being overcharged, over-discharged, short-circuited or overheated, and improve the stability and reliability of the energy storage module 400. The battery management module 402 can also establish a wired / wireless communication connection with the control module 500 so that the control module 500 receives the operation information of the energy storage module 400 and performs corresponding operations. For example, when the city power is cut off, during the power supply of the energy storage module 400, if it is detected that the stored energy of the energy storage device 401 is lower than the threshold, the control module 500 can control the switching module 600 to switch to the second power generation device 300 to power the data center load to avoid over-discharge. For another example, during the charging process of the energy storage module 400, if it is detected that the energy storage device 401 stores electric energy higher than a threshold value, the control module 500 can control the energy storage module 400 to stop charging; or, the control module 500 can also control the switching module 600 to switch the energy storage module 400 to the mains power supply, and control the energy storage module 400 to charge and discharge synchronously to avoid overcharging. For another example, when the control module 402 receives the fault information of the energy storage module 400, it can issue an alarm to remind the corresponding operation and maintenance personnel to perform maintenance.

[0047] In some embodiments, the battery management module 402 includes a sensor component, a battery control component and a communication component, and the communication component establishes a communication connection with the control module 500. In some embodiments, the sensor component includes but is not limited to current sensors, voltage sensors, temperature sensors and other sensors for real-time detection of parameters such as voltage, current, and temperature of the energy storage device 401. In some embodiments, the battery control component is used to determine the state of the energy storage device 401 (for example, determine the temperature, estimate the state of charge (SOC), battery health state (SOH), etc.) based on the various parameters of the energy storage device 401 detected, and execute the corresponding control strategy. For example, if it is detected that the temperature of the energy storage device 401 is higher than the threshold, the battery control component can control the start of the cooling fan in the energy storage device 401 to cool down. For another example, if an abnormal situation such as overcharging, over-discharging, short circuit, etc. is detected, the battery control component can control the disconnection of the circuit to ensure the safety of the power supply system. The battery control component includes but is not limited to various controllers that can be used for input, output, execution of logical judgment and control commands. In some embodiments, the communication component is also connected to the battery control component. The communication component can transmit the information received from the battery control component to the control module 500 through a wired / wireless communication connection with the control module 500 , so that the control module 500 can obtain the operating information of the energy storage module 400 .

[0048] In some embodiments, the switching module 600 includes a transfer switch component 601 and a power distribution component 602, the energy storage module 400 and the second power generation device 300 are connected to the transfer switch component 601, the transfer switch component 601 is connected to the power distribution component 602, and the power distribution component 602 is connected to the data center load. In some embodiments, the transfer switch component 601 includes but is not limited to a transfer switching equipment (Transfer Switching Equipment, TSE) or an automatic transfer switching equipment (Automatic Transfer Switching Equipment, ATSE). The transfer switch component 601 is used to automatically and / or manually switch the power supply. For example, when the city power is out of power, the transfer switch component 601 is connected to the energy storage module 400 for power supply. When the energy storage module 400 stores insufficient power, the second power generation device 300 is switched to supply power. This process can be performed automatically or under the instruction of the control module 500. In some embodiments, the power distribution component 602 includes but is not limited to power distribution equipment such as transformers and power distribution cabinets. The power distribution component 602 is used to adjust the power output by the energy storage module 400 or the second power generation device 300 to a voltage level suitable for use by various loads in the data center, and transmit it to the data center loads for use.
