Referring to fig. 1, a conventional data center employs a 2N data center power supply scheme. Taking three data centers as an example, assuming that the power consumption of each data center is 10MVA (megavolt ampere), two lines of commercial power are adopted for power supply, each line of commercial power needs to reach 30MVA commercial power capacity, and the total commercial power capacity of 60MVA needs to be introduced in total to meet the power consumption requirements of the three data centers with 10MVA power consumption. The power supply scheme has the disadvantages that in order to ensure the power supply reliability of the data center, a large amount of external commercial power is needed for standby, each external commercial power can bear the electric quantity (namely 30MVA electric capacity) required by the normal operation of the whole data center, the maximum utilization rate of the commercial power is only 50%, so that the utilization rate of the commercial power is low, the electric power resource is wasted, and a large amount of commercial power capacity cost is required.
The present specification provides a power supply system and a power supply method for supplying power to a plurality of data centers, which can reduce the capacity of required power supply energy and save cost. The power supply system and the power supply method according to the present specification will be described in detail below with reference to the accompanying drawings. The features of the following examples and embodiments may be combined with each other without conflict.
The embodiment of the specification provides a power supply system for supplying power to loads of a plurality of data centers, wherein an internet data center generally refers to a host storage environment with a series of conditions such as large-scale field and machine room facilities, high-speed and reliable internal and external network environments, and systematic monitoring support means. The data center includes two inputs, the power supply system includes: the data center comprises a plurality of data centers, a plurality of power supply circuits corresponding to the data centers in number, wherein each power supply circuit comprises an input end and two output ends, the input end of each power supply circuit is connected with different power supply energy sources, and the two output ends of each power supply circuit are connected with the input ends of different data centers. In the present embodiment, the power supply source is the commercial power, and in the following embodiments, the power supply source is taken as the commercial power for illustration. Of course, in other examples, the power supply source may also be renewable energy, wind power generation energy, hydroelectric power generation, photovoltaic power generation energy, and the like, which is not limited in this specification.
According to the technical scheme, the number of the power supply circuits is increased, so that each off-line commercial power only needs to supply power to loads of two different data centers, and the power supply system does not need to bear the electric quantity required by normal operation of all the data centers. Therefore, under the condition of ensuring the same power supply capacity, the utility power capacity of the used commercial power can be reduced, and further TCO (Total Cost of Ownership) of the data center power supply system can be reduced.
In an alternative embodiment, the power supply system of the present specification further includes a bus tie switch connected between two input terminals of the data center. It can be understood that two input ends of the data center are used for connecting output ends of different power supply circuits, namely the data center supplies power by adopting a double-circuit power supply circuit, and the bus coupler switch is arranged between the two input ends of the data center to realize bus coupler connection between the double-circuit power supply circuits of the data center, so that the normal power supply of the data center can be realized by carrying out bus coupler on the double-circuit power supply circuit through the bus coupler switch after power failure of any one circuit power supply circuit.
Referring to fig. 2, in an alternative embodiment, the plurality of data centers includes three data centers, namely a first data center 70, a second data center 80 and a third data center 90, which are independent from each other and have the same size, and the plurality of power supply circuits includes three power supply circuits, namely a first power supply circuit 10, a second power supply circuit 20 and a third power supply circuit 30, which correspond to the number of the data centers.

Further, a first transformer T1 is disposed between the input end 11 of the first power supply circuit 10 and the first commercial power, and the first transformer T1 is configured to step down the electric energy input by the first commercial power and provide the electric energy to the first power supply circuit 10.

A second switching device K2 is disposed between the input terminal 21 of the second power supply circuit 20 and the second transformer T2. A sixth switching device K6 is disposed between the first output end 22 of the second power supply circuit 20 and the first data center 70, and a seventh switching device K7 is disposed between the second output end 23 of the second power supply circuit 20 and the second data center 80.
A third transformer T3 is disposed between the input end 31 of the third power supply circuit 30 and the third commercial power, and the third transformer T3 is used for providing the third power supply circuit 30 with the electric energy input by the third commercial power after being reduced in voltage. A third switching device K3 is disposed between the input terminal 31 of the third power supply circuit 30 and the third transformer T3. An eighth switching device K8 is disposed between the first output end 32 of the third power supply circuit 30 and the second data center 80, and a ninth switching device K9 is disposed between the second output end 33 of the third power supply circuit 30 and the first data center 70.
It should be noted that the first utility power, the second utility power and the third utility power are generally 110KV utility power, and the first transformer T1, the second transformer T2 and the third transformer T3 are used for reducing the voltage of the corresponding utility power input to 10KV, which can be understood as that the first transformer T1, the second transformer T2 and the third transformer T3 represent three independent 10KV substations respectively.
In this embodiment, the first to ninth switching devices K1 to K9 all employ circuit breakers, and when a corresponding power supply circuit has a serious overload or short circuit or undervoltage fault, the circuit can be automatically cut off, so as to protect each power supply circuit.
Assuming that the power consumption of each data center is 10MVA, the first utility power, the second utility power and the third utility power are 110KV utility power, and the first transformer T1, the second transformer T2 and the third transformer T3 can step down the 110KV utility power to 10KV voltage, and then transmit the voltage to the corresponding first power supply circuit 10, the second power supply circuit 20 and the third power supply circuit 30. A transformer T4 may also be disposed inside the data center for stepping down the 10KV voltage transmitted by the corresponding power supply circuit to a low voltage (e.g., 380V) for supplying power to the load.
Under the condition that each utility power is normal, the first input end 71 of the first data center 70 introduces the electric energy of the first utility power through the first power supply circuit 10, the second input end 72 of the first data center 70 introduces the electric energy of the third utility power through the second power supply circuit 20, and the first utility power and the second utility power respectively only need to bear the electric quantity of 5MVA to meet the electric consumption of the first data center 70.
The first input end 81 of the second data center 80 introduces the electric energy of the second commercial power through the second power supply circuit 20, the second input end 82 of the second data center 80 introduces the electric energy of the third commercial power through the third power supply circuit 30, and the second commercial power and the third commercial power respectively only need to bear the electric quantity of 5MVA, so that the electric quantity used by the second data center 80 can be met.
The first input end 91 of the third data center 90 introduces the electric energy of the first commercial power through the first power supply circuit 10, the second input end 92 of the third data center 90 introduces the electric energy of the third commercial power through the third power supply circuit 30, and the first commercial power and the third commercial power respectively only need to bear the electric quantity of 5MVA, so that the electric quantity used by the third data center 90 can be met.
That is to say, under the condition that the first utility power, the second utility power and the third utility power are all normal, each utility power only needs to reach the 10MV utility power capacity, and the total utility power capacity of 30MVA needs to be introduced in total to meet the power consumption requirements of the data center with three 10MVA power consumption.
Referring to fig. 3, the power supply system may further include a bus tie switch K10 connected between two input terminals in each data center, in consideration of the possibility of any one of the utility power sources failing. With reference to the embodiment of fig. 2, a bus tie switch K10 is disposed between two input terminals of each of the first data center 70, the second data center 80, and the third data center 90, and a bus tie connection can be achieved through the bus tie switch K10. The two-way power supply circuit corresponding to the data center can be subjected to bus-coupled connection through the bus-coupled switch K10 in the data center, so that the power supply reliability can be improved. At the moment, the other two paths of commercial power respectively need to reach the commercial power capacity of 15MVA, and the three data centers with 10MVA power consumption can be met. Each line of commercial power needs to reach 15MVA commercial power capacity, and the total commercial power capacity of 45MVA needs to be introduced in total so that the power utilization requirements of three data centers with 10MVA power consumption can be still met when any one line of commercial power fails, and the maximum utilization rate of the commercial power under normal operation is about 66.7%. The two-way power supply circuit inside the data center is subjected to bus-coupled connection through the bus-coupled switch, the reliability of power supply requirements can be guaranteed while the safety of the commercial power capacity is guaranteed, and therefore when any one of the commercial power is powered off, the data center can still normally operate.
