Distributed UPS power supply system solution in data center. The
traditional deployment methods of UPS backup power include centralized and
distributed types. As long as there is a demand for uninterrupted power, an
uninterruptible power supply system UPS needs to be used. UPS is like an
electricity middleman. It can help infrastructure provide continuous and
uninterrupted power regardless of the size of the organization or how the power
consumption changes drastically.
Distributed UPS
Distributed UPSs are installed either directly on the server rack or next
to the server rack, resulting in all servers being connected to the UPS
hardware, leaving little or no space between the hardware and the servers. If a
distributed UPS is compared to a torch lighting channel configured every 4.5
meters in an area, then a centralized UPS can be compared to a large flashlight
that can illuminate a 30-meter radius area. When one of the distributed UPS
torches goes out, it will only darken the 4.5-meter area around it; but if the
large flashlight is temporarily extinguished, everything will be dark.
Distributed UPS power supply system solution in data center
The widespread application of mobile Internet and cloud computing has given
rise to the construction of a large number of data centers. According to data
released by the China Data Center Alliance, the scale of China's data center
power supply and energy storage market increased to 10 billion yuan in 2019;
among which, the market share of distributed UPS has been growing at a rate of
about 25% in recent years, and is expected to reach its market share in 2020 The
scale can reach 3.35 billion yuan.
Distributed UPS equipment provides continuous power supply for IT
equipment. The energy management system mainly provides energy consumption
management, energy storage management, energy scheduling, data mining and
automatic inspection for distributed power supply system equipment.
Corresponding to distributed UPS, China used to be dominated by centralized
UPS equipment. However, centralized UPS has the following problems:
1. Centralized UPS has high requirements on buildings. The power of
centralized UPS is generally between a few hundred kilowatts and megawatts. The
implementation of this type of large equipment has high requirements on
buildings, and it needs to start with the civil construction design of the
building. It requires little planning and is not easy to install.
2. With serious redundancy, enterprises will overestimate the UPS capacity
they need, resulting in a waste of energy. Excessive "energy" will bring
excessive "heat", thereby increasing the demand for the cooling system of the
data center and causing energy costs. high.
3. Concentrated risks and difficult operation and maintenance. Once there
is a problem with the centralized UPS itself, it will affect all aircraft
positions, and there is a certain technical threshold for troubleshooting. You
need to contact the manufacturer for technical support, and the customer itself
cannot respond quickly.
With the development of the Internet of Things, big data, AI, etc., and the
construction of 5G networks, the industry as a whole has put forward very high
requirements for real-time response to data. Distributed UPS power supply
systems are small in size, easy to install, and easy to manage in real time. and
other characteristics, are increasingly recognized by the market.
Advantages of distributed UPS in data center power supply system
1. Reliability: proximity strength
Since the distributed UPS is installed directly on or next to the servo
rack, the distance between them is shortened, and the probability of wiring
failure along the power line link can be greatly reduced. By deploying
self-contained auxiliary power along the entire network, you can prevent the
large-scale power outages that can occur with centralized UPS deployments.
2. Easy installation and integration
The light weight and high mobility make the installation and movement of
distributed UPS extremely simple, making it an ideal choice for data centers
that require high mobility. High proximity to server racks also gives
distributed UPS an advantage in Ethernet network connections.
3. Better cost control for small organizations
Since a distributed UPS is not designed to be used by the entire enterprise
network, but only a server rack within the network, the initial upfront cost of
purchasing this solution is much lower than that of a centralized UPS.
Just as the concept of "distributed UPS" is expressed, the outstanding
feature of distributed UPS is its geographical dispersion. Compared with
traditional power generation projects, it is smaller and more flexible, and is
dispersedly arranged near the user end. For new energy, the decentralized nature
of distributed energy can effectively solve the problem of inconsistent
development of renewable energy resources and load demand distribution in
China.
With the popularization of networks and the deepening of data centers,
equipment has become intelligent. How to effectively manage these devices,
improve work efficiency, and reduce management and maintenance costs have become
issues that UPS users must consider and face. Distributed UPS lithium battery is
specially designed for data centers. It combines the mature and stable control
technology of traditional UPS with new lithium battery energy storage
technology. It has the characteristics of small size, light weight, high
intelligence and easy deployment.
