Xi'an uninterruptible power supply (UPS) renovation project 3c40ks/40kva channel platform

  Qingpeng Technology (Xi'an UPS) channel supplier updates and transforms the 3c40ks/40kva platform of UPS project, and the research on the complete equipment replacement scheme of UPS project of financial industry data center
Based on the above optimization scheme, the 3c40ks/40kva channel platform of Xi'an UPS update and transformation project can replace all relevant supporting equipment of ups as a whole, The 3c40ks/40kva channel platform of Xi'an uninterruptible power supply (UPS) renovation project includes input cabinet, bypass cabinet, UPS host, battery and its switch cabinet With the business volume increasing year by year, the number of computer equipment on the 3c40ks/40kva channel platform of Xi'an uninterruptible power supply (UPS) renovation project is increasing, and the power consumption continues to increase
At present, some ups capacity has been unable to meet the power demand of equipment, and has become a bottleneck for the expansion of subsequent machine rooms
1、 Analysis of the front and rear power supply architecture of Xi'an uninterruptible power supply (UPS) 3c40ks/40kva take a large data center in the financial industry as an example
At present, the data center has deployed six groups of ups in specific areas, with a capacity of 1600KVA per assembly machine
It adopts a dual bus 2n redundant power supply architecture, which is divided into a/b two-way UPS, and each machine room has a/b two-way UPS power input
At the same time, the two-way mains power input of each group of UPS comes from different transformers, and both are equipped with diesel generator sets, which can start automatically in case of mains power interruption or voltage fluctuation
In addition, each set of UPS includes four UPS hosts, batteries, supporting power input cabinets and centralized output bypass cabinets, and is equipped with a 3200A input master switch and four 800A input switches, and each UPS host is equipped with a set of batteries (180Ah, 128 sections)
The structure of single UPS is shown in Figure 1

Current problems of Xi'an uninterruptible power supply (UPS) 3c40ks/40kva equipment 1
Equipment aging
The above uninterruptible power supply (UPS) 3c40ks/40kva equipment was officially put into operation at the beginning of 2007
It has been 14 years since now
During its operation, some components (including capacitors, power boards and cooling fans) were updated in 2016, and the update of supporting colloidal batteries was completed at the end of 2018
However, with the increase of the service life of the UPS equipment, the equipment is aging, the equipment failure rate is gradually increasing, and the operation risk is also gradually increasing
In order to ensure the power consumption of subsequent production, it is urgent to replace the original ups to improve the stability of UPS equipment operation
2
Insufficient equipment capacity as the business volume increases year by year, the number of computer equipment in the computer room of the data center continues to increase, and the power consumption continues to increase
At present, the above UPS capacity has been unable to meet the power demand of equipment, and has become a bottleneck for the expansion of subsequent machine rooms
In this regard, while the data center realizes the update of UPS equipment, it needs to expand the capacity of UPS equipment to make full use of the remaining resources of other existing basic environments and further improve the capacity of the computer room
3
There is a hidden trouble in the centralized bypass cabinet
Due to the early design of the ups architecture, the central centralized bypass parallel architecture mode is adopted
In this mode, after the bypass cabinet fails, the ups will not be able to automatically switch to the bypass, there is a single point of potential failure, and when the bypass cabinet is maintained, the ups needs to be switched to the maintenance bypass mode for operation
At this time, the subsequent computer equipment is powered by the mains power
If the mains power fluctuates or is interrupted, the power supply quality of the subsequent computer equipment may be affected, and the maintenance risk is high
4
Uninterruptible power supply (UPS) 3c40ks/40kva units have low input power factor and low operation efficiency
The above uninterruptible power supply (UPS) 3c40ks/40kva units are power frequency models produced more than ten years ago, with input power factor of only 0
9, high output power factor of only 0
8 at full load, and low operation efficiency of the whole machine (about 90%), It is significantly lower than the performance level of the current mainstream high-frequency UPS units (input power factor is more than 0
99, large output power factor is 1, and the overall efficiency is more than 95%), which not only cannot make full use of the capacity of the superior transformer, but also has a large calorific value, so it needs to be equipped with corresponding air conditioning units, resulting in unnecessary waste of resources
3、 Optimization scheme and implementation suggestions in view of the above difficulties, according to the current power supply architecture and power resource use status of the data center, this paper proposes a feasible scheme to realize the replacement of the whole ups by building a standby UPS power supply link
1
Overall replacement scheme for data centers with similar problems, it can be considered to use the surplus available power resources (including the transformer with surplus capacity and its standby output switch) to build a standby UPS power supply link, that is, the surplus transformer is used as the upper input power source of the standby UPS, and the output of the standby UPS is transmitted through the output cabinet through the cable to the output end of the corresponding post bus patch switch of the ups to be replaced, After that, the plug-in switch is cut in sequence, and the subsequent load of the ups to be replaced is switched to the standby UPS for power supply
The ups to be replaced is cut off and isolated from the existing power supply link as a whole, and then the UPS equipment to be replaced is replaced as a whole in turn
In addition, for ordinary users, if they are lack of corresponding resources in the above aspects, they can also consider using the original bypass to cut and replace multiple times
The backup UPS link is shown in Figure 2
Schematic diagram of backup uninterruptible power supply (UPS) 3c40ks/40kva link 2
Backup UPS site planning in the case described in this paper, considering site space, heat dissipation conditions, UPS input and output cable distance and other factors, a new set of backup UPS is planned to be deployed in the middle aisle space of the battery room on the north side of the original UPS machine room
At the same time, in view of the estimated large load of a single UPS group that needs to be replaced, the backup UPS capacity is configured as 2000kVA
The backup UPS is planned to be composed of four 500KVA high-frequency UPS units combined, using a decentralized bypass structure, including a backup UPS configuration input cabinet (switch capacity 1000a× 4), a parallel output cabinet (switch capacity 4000A), 688 batteries (43 × 4 groups × 4)
Among them, although the efficiency of 500KVA high-frequency UPS can reach more than 95%, the full load calorific value of the above four standby UPS is generally not higher than 100kW, and the remaining cooling capacity of the air conditioner in the battery room is 120kw, so there is no need to increase additional air conditioning resources, which can also meet the requirements of the standby UPS operating environment
3
During the process of building the backup UPS, by evaluating the capacity use of the existing 10kv/0
4kv transformer in the data center, the author found that the current No
8 transformer in No
4 substation has residual capacity, which can fully meet the load capacity requirements of the subsequent backup UPS, and the transformer output switch cabinet is equipped with ATS, which can be linked with the diesel generator, and can also complete automatic switching in case of mains power interruption or voltage fluctuation, Therefore, it is determined that the transformer is qualified to serve as a backup UPS input power supply
4
Backup UPS output link at present, the ups output of the above data center machine room is connected to the corresponding busbar patch switch in the machine room through the busbar, and then the patch switch is connected to the regional distribution cabinet of each machine room through the cable, so as to supply power to the computer equipment in the machine room
At the same time, considering that the pile head on the patch switch is connected with the ups output busbar, and the construction time of busbar disassembly and assembly is long, difficult and risky, the optimization scheme selects the connection between the pile head under the patch switch and the input cable of the power distribution cabinet in the machine room area as the access point of the standby UPS output link, so as to isolate and disconnect the UPS power supply link to be replaced, directly connect with the input cable of the power distribution cabinet in the machine room area, and supply power to the subsequent computer equipment
5
During the replacement of the original Xi'an uninterruptible power supply (UPS) 3c40ks/40kva complete machine, the above scheme chooses to power down and remove the original ups after all the loads are switched over to the standby ups
During the construction process, the backup ups will maintain two UPS power supply for the rear machine room
Therefore, there is no special requirement for the construction time, and there is sufficient time to install and test the newly installed UPS unit
In addition, it is planned to update four 500KVA high-frequency units with decentralized bypass structure
The capacity of the newly installed UPS unit is increased by 25% and the calorific value is reduced by 50% compared with that before replacement
It is worth noting that during the overall replacement of each group of UPS, during the process of switching the corresponding computer equipment in the back-up computer room to the standby UPS power supply and restoring the power supply to the new UPS, some related equipment in the back-up computer room need to be in the single UPS power supply operation state twice (about 2 hours each time), and the other time will maintain the dual UPS power supply state
To sum up, Xi'an uninterruptible power supply (UPS) 3c40ks/40kva based on the above optimization scheme, the financial data center can replace all relevant supporting equipment of ups as a whole, including input cabinet, bypass cabinet, UPS host, battery and its switch cabinet
From the perspective of effectiveness, the capacity, efficiency and stability of the ups unit have been significantly improved after replacement, which provides a guarantee for the operation and subsequent expansion of the subsequent machine room
