Abstract: In recent years, with the rapid development of data centers, the energy consumption problem of data centers has become more and more prominent. The energy management and power supply and distribution design of data centers have become hot issues. Reasonable and reliable data center power distribution system solutions , is a reasonable way to improve the power efficiency of the data center and reduce the energy consumption of the equipment.

1. Industry Policy

In 2020, data center construction was officially included in the new infrastructure strategy by the state. In recent years, it has received more and more attention from the state. Data centers are the basic guarantee for the orderly operation of new infrastructure and are regarded as "the infrastructure of new infrastructure."

On February 17, 2022, the National Development and Reform Commission and other departments officially released news, agreeing that Beijing-Tianjin-Hebei, Yangtze River Delta, Guangdong-Hong Kong-Macao Greater Bay Area, Chengdu-Chongqing and other places will start the construction of national hub nodes of the national computing power network. In addition, in December last year, Guizhou, Inner Mongolia, Gansu, and Ningxia received approval for the construction of national hub nodes of the national computing power network, and all the 8 major computing power hubs and 10 clusters of "East and Western Computing" have been implemented.

In October 2021, the State Council issued the "Notice of the State Council on Printing and Distributing the Action Plan for Carbon Peaking Before 2030", which proposed that "all data centers with an annual comprehensive energy consumption exceeding 10,000 tons of standard coal should be included in the online monitoring system for the main energy consumption unit energy consumption. , carry out energy measurement review. The "Shanghai Data Center Construction Guidelines (2021 Edition)" requires that the PUE value of new large-scale data centers in Shanghai should not be higher than 1.3.

2. Trend Analysis

It can be seen from the industry policy that the overall data center industry construction in the future is developing in the direction of scale and concentration. It also indicates that in the future, there will be many data center-related industries built and developed in these cluster cities such as "8 major computing power hubs and 10 clusters".

The development of centralization and scale will also lead to the emergence of better solutions for the overall power supply and distribution structure of the data center to meet the needs of policies, such as large-scale construction efficiency and a reasonable rate of energy utilization.

At present, the power distribution of the data center mainly includes AC 220V, DC 48V, DC 240V, DC 3336V. Data analysis diagram:

From the advantages and disadvantages of the above solutions, we can see that the DC 240V solution in the future may be more convenient to put into use in large quantities because of the simplicity, modularity, system capacity, etc. of expansion.

3. The terminal HVDC monitoring solution provided by Ankerui:

AMC100 series DC distribution monitoring device of Ankerui Company is a measuring device specially designed for the power management of data center servers for the DC column head cabinet of terminal power distribution. The device is compact in design, and can monitor all electrical parameters, input and output switches, and lightning arrester status of A+B two incoming lines and 192 outgoing lines in real time. The alarm thresholds of all measurement channels can be set independently. The limited event immediately triggers the sound and light alarm of the system, which realizes a high degree of integration of the monitoring loop in the volume of the traditional instrument.

AMC100 series module function parameters:

Different functional modules can be configured and selected for network splicing according to different customer needs, so as to meet the actual site needs of different customers and be flexibly matched.

Product wiring diagram:

With the local monitoring touch screen system, all power distribution information of the whole cabinet can be displayed on the spot, and faults can be detected in advance and early warning can be issued through data monitoring. It meets the requirements of reliable, safe and reasonable power consumption for power supply and distribution at the end of the data center.

Conclusion:

With the rapid development of communication technology and the impact of various factors such as the epidemic in recent years, online business has become a future trend, which has also brought unprecedented strong demand to the data center industry. With the recovery of the social economy, the development and construction of data centers will usher in rapid development, coupled with the strong support given by national policies, all of which have brought great advantages to the development of the data center industry.
