At present, as the demand of users for data storage increases, the scale of a data center can be enlarged, and the power supply demand of the data center with larger scale is also larger.
The related technology adopts a 220kV transformer substation to supply power for a data center with a larger scale, and can meet the condition of large power supply requirement of the data center. But the low voltage side of 220kV substations typically uses a voltage level of 10 kV. Because the voltage class of 10kV is lower, the impedance of the corresponding main transformer is larger, so that the power supply loss of the transformer substation is larger, and the power supply efficiency of the transformer substation is influenced.
In view of this, the embodiment of the disclosure provides a power supply system for a data center and the data center, in the process of supplying power to the data center, a 220kV/20kV transformer substation is adopted, and compared with a 220kV/10kV transformer substation, the voltage class of the low-voltage side of the transformer substation is improved. Therefore, the power supply loss of the transformer substation is reduced, and the power supply efficiency of the transformer substation is improved.
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application.
All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application. The following embodiments and features of the embodiments may be combined with each other without conflict.
As shown in connection with fig. 1, a data center 100 provided by an embodiment of the present disclosure may include a power supply system 11, a power distribution device 12, and at least one server 13, wherein the power distribution device 12 is configured to distribute power provided by the power supply system 11 to the server 13.
As shown in connection with fig. 1 and 2, a power supply system 11 provided by an embodiment of the present disclosure may include a substation 21, a power distribution system 22. Wherein:
A transformer substation 21, which is 220kV/20kV, is connected with the power grid 20 and the power distribution system 22 respectively, and is configured to convert the 220kV voltage output by the power grid 20 into 20kV voltage and output the 20kV voltage to the power distribution system 22;
The power distribution system 22, which is 20kV, is connected to the power distribution equipment 12 of the data center 100, and is configured to distribute the 20kV voltage output from the substation to the power distribution equipment 12 of the data center 100.
By adopting the power supply system for the data center, which is provided by the embodiment of the disclosure, in the process of supplying power to the data center, a 220kV/20kV transformer substation is adopted, and compared with a 220kV/10kV transformer substation, the voltage level of the low-voltage side of the transformer substation is improved. Therefore, under the condition that the power supply capacity of the 220kV transformer substation is not changed, the voltage grade of the low-voltage side of the transformer substation is improved, and the impedance of the main transformer in the transformer substation can be reduced. Therefore, the power supply loss of the transformer substation is reduced, and the power supply efficiency of the transformer substation is improved.
Alternatively, as shown in connection with fig. 3, the substation 21 comprises an input 211, a main transformer 212 and an output 213, which are connected in sequence. The input terminal 211 is connected to the power grid 20, and can receive 220kV voltage input by the power grid 20. Main transformer 212 may step down a 220kV voltage to a 20kV voltage. The output terminal 213 is connected to the power distribution system 22, and is capable of outputting a voltage of 20kV to the power distribution system 22. In this embodiment, the low voltage side of main transformer 212 is connected in a double-branch manner, and
The main transformer 212 need not take the form of split windings. Thus, the reactive configuration of main transformer 212 is reduced.
Optionally, as shown in connection with fig. 3, power distribution system 22 includes an incoming line cabinet 221, a bus bar 222, an outgoing line 223, and a step-down transformer 224. The incoming line cabinet 221 is connected with the transformer substation 21, and can receive 20kV voltage output by the transformer substation 21. The bus 222 is connected to the incoming line cabinet 221 and can receive the voltage of 20kV distributed by the incoming line cabinet 221. The outlet 223 is connected to the bus bar 222 and can transmit the 20kV voltage of the bus bar 222 to the step-down transformer 224. Step-down transformer 224, connected to outlet 223 and distribution equipment 12 of data center 100, respectively, may convert the 20kV voltage to a voltage equivalent to the voltage level of data center 100. In this embodiment, the main transformer 212 corresponds to only two bus bars 222, and only 2 incoming line cabinets 221 are needed. In this way, the structure of the power supply system is simpler, and the number of corresponding outgoing lines 223 is also smaller. Thus, the use and paving costs of outlet 223 are reduced.
Optionally, as shown in connection with fig. 2, 3 and 4, the power supply system 11 provided in the embodiment of the present disclosure further includes a voltage level detection device 23 and a controller 24. Wherein:
the voltage level detection device 23 is connected to the power distribution equipment 12 of the data center 100, and can detect the voltage level of the data center through the power distribution equipment 12.
The controller 24 is connected to the voltage class detecting device 23 and the power distribution system 22, respectively, and the controller 24 may control the power distribution system 22 to convert the voltage of 20kV into a voltage equivalent to the voltage class according to the voltage class of the data center 100. For example, the voltage level of the data center 100 is 10kV, and the power distribution system 22 steps down the voltage of 20kV to 10kV through the step-down transformer 24, so that the voltage provided by the power supply system 11 can be normally used by the data center 100. In this way, matching the voltage provided by the power supply system 11 with the voltage class of the data center can improve the adapting capability of the power supply system 11, so that the application range of the power supply system 11 is wider. In addition, the power supply system 11 in this embodiment does not require hardware adjustment of the power distribution equipment 12 of the data center 100, thereby saving costs.
Optionally, as shown in connection with fig. 2 and 4, the power supply system 11 provided in the embodiment of the present disclosure further includes a photovoltaic power supply 25 and a wind power supply 26. The controller 24 may obtain the power supply requirement of the data center 100, and control the photovoltaic power supply device 25 and/or the wind power supply device 26 to be started when the power output by the power supply system 11 cannot meet the power supply requirement. Thus, better power supply to the data center 100 is facilitated, so that abnormal situations of the data center 100 due to insufficient power supply are reduced.
Optionally, as shown in connection with fig. 2 and 4, the power supply system 11 provided in the embodiment of the present disclosure further includes a heat dissipating device 27. The controller 24 may determine whether the temperature of the power supply system 11 is higher than a temperature threshold, and control the heat sink 27 to be turned on when the temperature of the power supply system 11 is higher than the temperature threshold. Therefore, heat dissipation is performed on the power supply system 11 in time, so that the situation of abnormal high temperature of the power supply system 11 is reduced.
Based on the data center described above, the disclosed embodiments also provide a power control method for a data center, which can be applied to the controller 24 of the data center 100. Referring to fig. 5, the method includes:
S51, acquiring the voltage level of the data center 100.
S52, according to the voltage class of the data center 100, the power distribution system 22 is controlled to convert the voltage of 20kV into a voltage equivalent to the voltage class.
By adopting the power supply control method for the data center provided by the embodiment of the disclosure, the voltage provided by the power supply system 11 can be matched with the voltage class of the data center, so that the adaptive capacity of the power supply system 11 is improved, and the application range of the power supply system 11 is widened. In addition, the power supply system 11 in this embodiment does not require hardware adjustment of the power distribution equipment 12 of the data center 100, thereby saving costs.
Optionally, the power supply control method further includes: in case the power output by the power supply system 11 fails to meet the power supply demand, the photovoltaic power supply 25 and/or the wind power supply 26 are controlled to start. Thus, better power supply to the data center 100 is facilitated, so that abnormal situations of the data center 100 due to insufficient power supply are reduced.
Optionally, the power supply control method further includes: and judging whether the temperature of the power supply system is higher than a temperature threshold value. In case the temperature of the power supply system 11 is higher than the temperature threshold, the heat sink 27 is controlled to be turned on. Therefore, heat dissipation is performed on the power supply system 11 in time, so that the situation of abnormal high temperature of the power supply system 11 is reduced.
