DATA CENTRE PREDICTIONS
Trend 3 : UPS with lithium batteries becomes a new choice for data centres
The battery is a key component of the power supply and distribution system . As the final guarantee of power supply , the status of the battery directly affects the normal operation of the power supply and
1.5 MW power supply and distribution . Uninterruptible power systems ( UPSs ) need to be connected in parallel to meet the requirement . However , it ’ s complex for the power supply and distribution of the parallel system , which occupies too large of a footprint and increases the difficulty of construction because of too many cabinets and cables .
For example , a parallel system of three UPS ’ requires 14 groups of cables to be connected and the installation takes about 120 manual hours . In addition , the power distribution system , UPS and battery monitoring are separated . When a fault occurs on the power supply link , multiple alarms are generated . As a result , an alarm storm occurs and fault locating is difficult . Some major risks cannot be proactively isolated , incurring potential risks .
The integrated design solution for power supply and distribution system :
• Integrates the UPS input and output cabinets with the UPS
• Simplifies power configuration , reducing footprint and installation time
• Monitors the full power supply and distribution link , enabling quickly fault locating for higher reliability
Trend 2 : Modular design for higher O & M efficiency
The maximum efficiency of both the highfrequency tower UPS and the modular UPS can reach 96 % at above 50 % load .
However , the UPS load rate is about 20 %– 40 % in common working conditions . The efficiency of high-frequency tower UPS can be only 94 %– 95 % under common working conditions . However , the efficiency of modular UPS can be up to 96 %, because the mainstream modular UPS provides the module hibernation feature , which enables a certain number of modules to be hibernated ( manual or automatic ) with certain system redundancy retained . This allows the UPS to work with high efficiency ( around the highest efficiency point of 96 %).
In addition , for the high-frequency tower UPS , capacity expansion is difficult , O & M is complex and maintenance skill requirements are high . The risk of misoperations by technical personnel of the data centre increases greatly . When a fault occurs , the fault cannot be rectified quickly even if spare parts are available and the system must be maintained by the after-sales personnel of the original manufacturer . As a result , the system recovery period is long , which increases the risk of service interruption .
The modular UPS supports online hot swap which adapts to dynamic service development . The maintenance time is shortened to five minutes , which greatly reduces the risk of service interruption caused by power supply problems . The higher reliability of modular UPS can meet the simple O & M requirements of a data centre . A traditional UPS is also incomparable to a modular UPS in terms of efficiency , maintainability and scalability .
