Description

Technical Field

[0001] The present disclosure relates to the field of power supply and distribution technology, and in particular to a power supply architecture of a data center. Background Art

[0002] At present, the power supply architecture of submarine data centers usually adopts a mutual backup architecture (2N). The 2N architecture has the characteristics of high power reliability, high availability, convenient operation and maintenance, high overall construction cost and high operating cost. In order to reduce the overall construction and operating costs, submarine data centers can appropriately consider the distributed redundant power distribution architecture (also known as the Distributed Redundancy architecture, referred to as the DR architecture).

[0003] When the submarine data center adopts the DR architecture, due to capacity limitations, multiple low-voltage systems are not connected by busbars. When a transformer or low-voltage busbar of one power source fails and causes a power outage, the uninterruptible power supply (UPS) will provide power to the data center load. When the battery of the UPS power supply is discharged, the battery cannot be charged in time, shortening the battery life. Utility Model Content

[0004] In view of this, the present disclosure provides a power supply architecture for a data center to solve the problem that the battery of a UPS power supply cannot be charged in time after being discharged, thereby shortening the battery life.

[0006] The power supply architecture of the data center provided by the present invention includes at least two sets of power supply modules. The main input interface, bypass input interface and bypass input interface of the uninterruptible power supply of each power supply module are connected to the power supply of the power supply module through the first circuit breaker, the second circuit breaker and the third circuit breaker respectively, and the output interface is connected to part of the data center load through the fifth circuit breaker. In addition, the main input interface is also connected to the power supply of another power supply module through the fourth circuit breaker. When the controller detects that there is no current on the output side of the first circuit breaker, the second circuit breaker, the third circuit breaker and the fifth circuit breaker, the controller sends a disconnection instruction to the control circuit of the fifth circuit breaker and sends a closing instruction to the control circuit of the fourth circuit breaker, so that when the uninterruptible power supply is discharged, the uninterruptible power supply is powered by the power supply of another power supply module, so that the battery of the uninterruptible power supply can be effectively and timely charged to protect the service life of the battery.

[0007] In some optional embodiments, the controller is further configured to keep the fourth circuit breaker open when any one of the current sensors respectively disposed at the output sides of the first circuit breaker, the second circuit breaker and the third circuit breaker detects current.

[0008] In the power supply architecture of the data center in this embodiment, when the controller detects that there is current on the output side of any one of the first circuit breaker, the second circuit breaker and the third circuit breaker, it indicates that the power supply of the power supply module is supplying power. At this time, there is no need to borrow the power supply of another power supply module to charge the uninterruptible power supply. This clarifies the situation in which the power supply is not borrowed to charge the uninterruptible power supply, thereby improving the efficiency of charging the uninterruptible power supply.

[0016] The power supply architecture of the data center in this embodiment further clarifies the method of evenly distributing the entire data center load among the uninterruptible power supplies in each power supply module, so that the uninterruptible power supply of each module operates at a non-full load state, thereby improving the reliability of the operation of each uninterruptible power supply.

[0017] In some optional embodiments, when abnormal power supplies exist in at least two sets of power supply modules, the uninterruptible power supplies in the power supply modules without the abnormal power supplies evenly distribute the entire data center load.

[0018] The power supply architecture of the data center in this embodiment further clarifies that when there is an abnormal power supply, the uninterruptible power supply in the power supply module without the abnormal power supply evenly distributes all data center loads, thereby ensuring the normal power supply of the data center load, and realizing the effective utilization of the uninterruptible power supply in the power supply module with normal power supply, thereby improving the efficiency of power supply via the uninterruptible power supply.

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0028] In this embodiment, a power supply architecture of a data center is provided. Figure 1 is an exemplary architecture diagram of a power supply architecture of a data center according to an embodiment of the present disclosure, such as Figure 1 As shown, the power supply architecture includes: a power supply 110 , an uninterruptible power supply 120 and a controller 130 .

[0029] The power supply 110 is used to supply power to the uninterruptible power supply.

[0030] The power supply 110 may be a power supply that provides electrical energy for the data center load using existing technologies or future technologies such as city electricity and a diesel generator set.

[0031] The uninterruptible power supply 120 includes a main input interface, a bypass input interface, a bypass input interface and an output interface. The main input interface, the bypass input interface and the bypass input interface are connected to the power supply 110 through the first circuit breaker S1, the second circuit breaker S2 and the third circuit breaker S3 respectively. The main input interface is connected to the power supply 110 of another power supply module through the fourth circuit breaker S4, and the output interface is connected to part of the data center load through the fifth circuit breaker S5.

[0032] The uninterruptible power supply 120 includes: a main input interface, a bypass input interface, a bypass input interface and an output interface. Circuit breakers are respectively provided in the paths of the main input interface, the bypass input interface and the bypass input interface connected to the power supply to control the connection and disconnection of each power supply path. A circuit breaker is provided in the path of the output interface connected to the load to control the connection and disconnection of the load path.

[0033] Specifically, the main input interface is the input interface of the main power supply path, which can provide high-quality AC power to the load via the output interface, thereby achieving functions such as voltage stabilization, frequency stabilization, filtering, anti-electromagnetic and radio frequency interference, and anti-voltage surfing. The bypass input interface is the input interface of the backup power supply path, which can make the power supply more reliable, so that the computers in the data center can be powered even when the uninterruptible power supply 120 fails or the load is overloaded. The bypass input interface can not interrupt the power supply to the load when the host of the uninterruptible power supply 120 is overhauled.

[0034] The controller 130 includes an input port and an output port, the input port is respectively connected to current sensors arranged on the output sides of the first circuit breaker S1, the second circuit breaker S2, the third circuit breaker S3, the fourth circuit breaker S4 and the fifth circuit breaker S5, and the output port is connected to the control circuit of the fourth circuit breaker S4 and the control circuit of the fifth circuit breaker S5. The controller 130 is configured to: when the current sensors arranged on the output sides of the first circuit breaker S1, the second circuit breaker S2, the third circuit breaker S3 and the fifth circuit breaker S5 respectively detect no current, send a disconnect command to the control circuit of the fifth circuit breaker S5, and send a closing command to the control circuit of the fourth circuit breaker S4.

[0035] The controller 130 includes an input port and an output port. The input port of the controller 130 receives the current data sent by the current sensors on the output sides of the first circuit breaker S1, the second circuit breaker S2, the third circuit breaker S3, the fourth circuit breaker S4 and the fifth circuit breaker S5 respectively. The controller 130 can be implemented by a device with a control function in the existing technology or the technology to be developed in the future, and this application does not limit this. For example, the controller 130 can be a programmable logic controller PLC, a remote I / O controller or a single-chip microcomputer controller, a computer device, etc.

[0036] Specifically, when the current data indicates that there is no current on the output sides of the first circuit breaker S1, the second circuit breaker S2, and the third circuit breaker S3, it means that the power supply 110 of the power supply module is not supplying power to the uninterruptible power supply 120 at this time; when there is no current on the output side of the fifth circuit breaker S5, it means that the uninterruptible power supply 120 has finished discharging to the outside. At this time, the uninterruptible power supply 120 needs to be charged, so a disconnection instruction can be sent to the control circuit of the fifth circuit breaker S5 to disconnect the load of the uninterruptible power supply 120; and a closing instruction can be sent to the control circuit of the fourth circuit breaker S4 to use the power supply 110 of another power supply module connected to the fourth circuit breaker S4 to charge the uninterruptible power supply 120.

[0037] The current sensor here may be a current transformer or other types of sensors that can be used to measure current. Those skilled in the art may select a suitable type according to specific application scenarios and requirements, and this application does not limit this.

[0038] The power supply architecture of the data center provided in this embodiment includes at least two sets of power supply modules. The main input interface, bypass input interface, and bypass input interface of the uninterruptible power supply 120 of each power supply module are connected to the power supply 110 of the power supply module through the first circuit breaker S1, the second circuit breaker S2, and the third circuit breaker S3 respectively, and the output interface is connected to part of the data center load through the fifth circuit breaker S5. In addition, the main input interface is also connected to the power supply 110 of another power supply module through the fourth circuit breaker S4. When the controller 130 detects that there is no current on the output side of the first circuit breaker S1, the second circuit breaker S2, the third circuit breaker S3 and the fifth circuit breaker S5, it sends a disconnection instruction to the control circuit of the fifth circuit breaker S5 and sends a closing instruction to the control circuit of the fourth circuit breaker S4, so that when the power supply 110 of the current power supply module cannot supply power and the uninterruptible power supply 120 is discharged, the uninterruptible power supply 120 is powered by the power supply 110 of another power supply module, so that the battery of the uninterruptible power supply 120 can be effectively and timely charged to protect the service life of the battery.

[0039] In some optional embodiments, in the power supply architecture of the data center in the above embodiments, the controller is further configured to: keep the fourth circuit breaker disconnected when any current sensor of the current sensors respectively arranged on the output sides of the first circuit breaker, the second circuit breaker and the third circuit breaker detects current.

[0040] In the power supply architecture of the data center in this embodiment, when the controller detects that there is current on the output side of any one of the first circuit breaker, the second circuit breaker and the third circuit breaker, it indicates that the power supply of the power supply module is supplying power. At this time, there is no need to borrow the power supply of another power supply module to charge the uninterruptible power supply. This clarifies the situation in which the power supply is not borrowed to charge the uninterruptible power supply, thereby improving the efficiency of charging the uninterruptible power supply.

[0041] In some optional implementations, the main input interface of the uninterruptible power supply is a normal power supply interface, and the main input interface is connected to part of the data center load through the rectifier, inverter and fifth circuit breaker of the uninterruptible power supply.

[0042] In this embodiment, taking the mains input as an example, when the mains input is normal, the uninterruptible power supply stabilizes the mains through the rectifier and inverter and supplies it to the load for use. At this time, the uninterruptible power supply is an AC voltage stabilizer, and it also charges the battery inside the uninterruptible power supply; when the mains is interrupted (accidental power outage), the uninterruptible power supply immediately switches the DC power of the battery to the load through the inverter switching conversion method to continue to supply 220V AC power to the load, so that the load maintains normal operation and protects the load software and hardware from damage. Uninterruptible power supply equipment can usually provide protection against overvoltage or undervoltage.

[0043] The power supply architecture of the data center in this embodiment ensures the efficiency of normal power supply through the uninterruptible power supply by clearly defining the situation in which the data center load is powered through the main input interface of the uninterruptible power supply.

[0044] In some optional embodiments, the bypass input interface of the uninterruptible power supply is a power supply interface used when the load exceeds the rated load or the inverter in the uninterruptible power supply fails. The bypass input interface is connected to part of the data center load through the static switch and the fifth circuit breaker in sequence.

[0045] In this embodiment, the uninterruptible power supply uses two reverse-parallel thyristors to form a static switch. The static switch in the uninterruptible power supply plays a key role in data protection, making the power supply more reliable. Even when the load is overloaded or the main path of the uninterruptible power supply fails (for example, the inverter fails and the AC power supply and the DC power provided by the battery cannot supply power), the computers in the data center load can still be powered. When the input end is the positive half cycle of the sine wave voltage, the gate trigger pulse of the thyristor VS1 turns on VS1, and the power supply supplies power to the load through VS1; VS1 is turned off when the AC passes through zero. When the input voltage is the negative half cycle, the thyristor VS2 is subjected to the positive anode voltage, and the gate trigger pulse of VS2 turns on VS2, and the power supply supplies power to the load through VS2.

[0046] The power supply architecture of the data center in this embodiment ensures that the data center can supply power to part of the data center load when the uninterruptible power supply is overloaded or the uninterruptible power supply is abnormal, thereby ensuring the power supply efficiency of the uninterruptible power supply.

[0047] In some optional implementations, the maintenance input interface of the uninterruptible power supply is a power supply interface used when the uninterruptible power supply is repaired, and the maintenance input interface is connected to part of the data center load through the fifth circuit breaker.

[0048] In this embodiment, after the uninterruptible power supply fails, the mains power is directly connected to the data center load through the maintenance input interface, and the uninterruptible power supply is disconnected, thereby not affecting the maintenance of the uninterruptible power supply.

[0049] The power supply architecture of the data center in this implementation ensures the power supply efficiency of the uninterruptible power supply by specifying the situation where the uninterruptible power supply input interface supplies power to part of the data center loads.

[0050] In some optional embodiments, the uninterruptible power supplies in at least two sets of power supply modules evenly distribute the entire data center load.

[0051] In a specific example, there are four sets of power supply modules supplying power to three groups of data center loads, and the uninterruptible power supplies in the four sets of power supply modules evenly distribute all data center loads, that is, the load of the uninterruptible power supply in each power supply module is 75% of the load of a single group of data center loads.

[0052] The power supply architecture of the data center in this embodiment further clarifies the method of evenly distributing the entire data center load among the uninterruptible power supplies in each power supply module, so that the uninterruptible power supply of each module operates at a non-full load state, thereby improving the reliability of the operation of each uninterruptible power supply.

[0053] In some optional embodiments, when abnormal power supplies exist in at least two sets of power supply modules, the uninterruptible power supplies in the power supply modules without the abnormal power supplies evenly distribute the entire data center load.

[0054] Among them, abnormal power supply refers to power supply that cannot supply power normally, such as power supply under the circumstances of city power outage, transformer busbar failure, etc.

[0055] In a specific example, there are four sets of power supply modules supplying power to three groups of data center loads. When one of the uninterruptible power supplies in the four power supply modules fails to supply power normally, the uninterruptible power supplies of the remaining three normal power supply modules evenly distribute all the data center loads, that is, the load of the uninterruptible power supply in each power supply module is 100% of a single group of data center loads.

[0056] The power supply architecture of the data center in this embodiment further clarifies that when there is an abnormal power supply, the uninterruptible power supply in the power supply module without the abnormal power supply evenly distributes all data center loads, thereby ensuring the normal power supply of the data center load, and realizing the effective utilization of the uninterruptible power supply in the power supply module with normal power supply, thereby improving the efficiency of power supply via the uninterruptible power supply.

[0057] In this embodiment, a power supply method for a data center is provided, wherein the power supply architecture of the data center includes: at least two sets of power supply modules, the power supply modules include: a power supply for supplying power to an uninterruptible power supply; an uninterruptible power supply, a main input interface, a bypass input interface, and a bypass input interface are connected to the power supply through a first circuit breaker, a second circuit breaker, and a third circuit breaker respectively, a main input interface is connected to a power supply of another power supply module through a fourth circuit breaker, and an output interface is connected to a part of the data center load through a fifth circuit breaker; a controller, an input port is connected to current sensors provided on the output sides of the first circuit breaker, the second circuit breaker, the third circuit breaker, the fourth circuit breaker, and the fifth circuit breaker respectively, and an output port is connected to a control circuit of the fourth circuit breaker and a control circuit of the fifth circuit breaker; the power supply method is executed on the controller, Figure 2 FIG. 1 is a flow chart of a power supply method for a data center according to an embodiment of the present disclosure. Figure 2 As shown, the process includes the following steps:

[0058] Step S201, via the current sensors provided at the output sides of the first circuit breaker, the second circuit breaker, the third circuit breaker, the fourth circuit breaker and the fifth circuit breaker, determine whether the paths where the first circuit breaker, the second circuit breaker, the third circuit breaker, the fourth circuit breaker and the fifth circuit breaker are located detect current.

[0059] Among them, the output sides of the first circuit breaker, the second circuit breaker, the third circuit breaker and the fifth circuit breaker are all provided with current sensors for monitoring whether there is current in the corresponding four paths. When there is current in the paths corresponding to the first circuit breaker, the second circuit breaker and the third circuit breaker, it indicates that the power supply of this power supply module is supplying power normally. When there is current in the path where the fifth circuit breaker is located, it indicates that this power supply module is supplying power to the load of the data center normally, which may be powered by the power supply or the battery of the uninterruptible power supply.

[0060] Step S202: When the current sensors respectively arranged at the output sides of the first circuit breaker, the second circuit breaker, the third circuit breaker and the fifth circuit breaker detect no current, a disconnection command is sent to the control circuit of the fifth circuit breaker, and a closing command is sent to the control circuit of the fourth circuit breaker.

[0061] Among them, when the current data indicates that there is no current on the output sides of the first circuit breaker, the second circuit breaker, and the third circuit breaker, it means that the power supply of the power supply module is not supplying power to the uninterruptible power supply at this time; when there is no current on the output side of the fifth circuit breaker, it means that the uninterruptible power supply has finished discharging to the outside. At this time, the uninterruptible power supply of the power supply module needs to be charged, so a disconnection instruction can be sent to the control circuit of the fifth circuit breaker to disconnect the load of the power supply module; and a closing instruction can be sent to the control circuit of the fourth circuit breaker to use the power supply of another power supply module connected to the fourth circuit breaker to charge the uninterruptible power supply.

[0062] The power supply method for a data center provided in this embodiment and the power supply architecture of a data center include at least two sets of power supply modules. The main input interface, bypass input interface and bypass input interface of the uninterruptible power supply of each power supply module are connected to the power supply of the power supply module through the first circuit breaker, the second circuit breaker and the third circuit breaker respectively, and the output interface is connected to part of the data center load through the fifth circuit breaker. In addition, the main input interface is also connected to the power supply of another power supply module through the fourth circuit breaker, so that when the controller detects that there is no current on the output side of the first circuit breaker, the second circuit breaker, the third circuit breaker and the fifth circuit breaker, the controller sends a disconnection instruction to the control circuit of the fifth circuit breaker and sends a closing instruction to the control circuit of the fourth circuit breaker, so that when the power supply of the current power supply module cannot supply power and the uninterruptible power supply is discharged, the uninterruptible power supply is powered by the power supply of another power supply module, so that the battery of the uninterruptible power supply can be effectively and timely charged to protect the service life of the battery.

[0063] In some optional implementations, the power supply method may further include step S203, when any current sensor of the current sensors respectively arranged at the output sides of the first circuit breaker, the second circuit breaker and the third circuit breaker detects current, keeping the fourth circuit breaker disconnected.

[0064] In this optional implementation, when the controller detects that there is current on the output side of any one of the first circuit breaker, the second circuit breaker and the third circuit breaker, it indicates that the power supply of the power supply module is supplying power. At this time, there is no need to borrow the power supply of another power supply module to charge the uninterruptible power supply. This clarifies the situation in which the power supply is not borrowed to charge the uninterruptible power supply, thereby improving the efficiency of charging the uninterruptible power supply.

[0065] As a specific application example of the present disclosure, the following is combined with Figure 3 The power supply architecture of the data center of the present disclosure is described.

[0066] Figure 3 An exemplary schematic diagram of a power supply architecture of a data center is shown.

[0067] like Figure 3 As shown, the data center is powered by mains power supply 1 and mains power supply 2. Among them, mains power supply 1 and mains power supply 2 supply power to the data center via two sets of transformers respectively. In this power supply system, each set of transformers, UPS power supply and PLC controller constitutes a set of power supply modules, and 4 sets of power supply modules supply power to the data center. The power supply of each power supply module is the output of the transformer. The main input interface, bypass input interface and bypass input interface of the UPS power supply are connected to the output of the transformer through the first circuit breaker, the second circuit breaker and the third circuit breaker respectively. The main input interface of the UPS power supply is connected to the output of another transformer through the fourth circuit breaker, and the output interface of the UPS power supply is connected to part of the data center load (such as Figure 3 The input port of the PLC controller is respectively connected to the current sensors arranged on the output sides of the first circuit breaker, the second circuit breaker, the third circuit breaker, the fourth circuit breaker and the fifth circuit breaker, and the output port of the PLC controller is connected to the control circuit of the fourth circuit breaker and the control circuit of the fifth circuit breaker. When the PLC controller detects that there is no current on the output sides of the first circuit breaker, the second circuit breaker, the third circuit breaker and the fifth circuit breaker through the current sensor, the PLC controller sends an opening instruction to the control circuit of the fifth circuit breaker and sends a closing instruction to the control circuit of the fourth circuit breaker. At this time, the output of another transformer charges the UPS. When any current sensor of the current sensors arranged on the output sides of the first circuit breaker, the second circuit breaker and the third circuit breaker detects current, the PLC controller keeps the fourth circuit breaker open.
