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.
