Project OverviewAcrel Precision Power Distribution Cabinet Helps Data Center Save Energy and Reduce Consumption 0 Foreword
In recent years, with the vigorous development of the digital economy, the supporting role of data centers in the new infrastructure system has become more and more prominent. While enabling the digital transformation of thousands of industries, the huge energy consumption problem brought about by it has also attracted great attention from the society. . According to data released by the Ministry of Ecology and Environment. In 2021, our country’s data centers consumed 2.6% of the electricity consumption of the whole society, and carbon emissions accounted for about 1.14% of the country’s carbon emissions. It is predicted that the society’s demand for computing power will grow at a rate of more than 20% per year, and the industry’s demand for electricity will continue to increase.
In March 2022, the number of racks in my country will increase rapidly after the launch of the “East and West” project proposed by the state. According to statistics, there are only 5 national computing power network hub nodes in Beijing-Tianjin-Hebei, Yangtze River Delta, Chengdu-Chongqing, Gansu and Ningxia, 7 data from Zhangjiakou in northern Hebei, Yangtze River Delta, Wuhu in Anhui, Tianfu in Sichuan, Chongqing, Qingyang , Gansu and Zhongwei in Ningxia. For the central cluster, the number of standard racks currently planned for construction has exceeded 5 million.
1 Trend Analysis
Energy expenditure is one of the main costs of data center operation. Gao Wensheng, executive vice president of the Energy Internet Innovation Research Institute of Tsinghua University. Once pointed out in public that as the energy consumption of data centers in our country increases year by year, electricity expenses account for about 95% of the annual operating costs of data centers. Coupled with the introduction of the “dual carbon” strategy, the central and local governments have put forward higher requirements for data center energy consumption indicators. As a result, the energy management and power supply and distribution design of data centers have become popular issues. An efficient and reliable data center power distribution system solution is an effective way to improve the power efficiency of data centers and reduce equipment energy consumption.
2 User needs
The difficult problem faced by the data industry under the rapid development: how to achieve both development and carbon reduction, but also reduce costs?The expectation put forward by people in the data industry is: control carbon but not electricity. Carbon control means that the data center can use green power as much as possible.And at the same time, comprehensive energy management can be achieved to achieve energy saving and reduce carbon emissions. And this is also one of the goals of the “East and West” project.
3 Acrel precision power distribution column cabinets help data centers save energy and energy
Acrel has been committed to smart grid terminals since its establishment. As a data center participant and energy-saving service provider.Acrel is making efforts in “source, network, load, storage, operation and maintenance” and other links, through a complete set of data center energy efficiency management solutions to help The new data center achieves the goal of “dual carbon”, among which the precision power distribution column head cabinet introduced comprehensively collects all energy data for the energy end of the data center room. Provide high-precision measurement data for the terminal energy monitoring system, reflect the power quality data in real time through the display unit, and upload the data to the DCIM system through RS485 communication.So as to achieve real-time monitoring of the entire power distribution system and management of operation quality, and meet absolute requirements of most data centers.
3.1 Application scheme
Acrel precision power distribution cabinet is composed of HMI touch screen, main line incoming line acquisition and monitoring module, branch circuit electrical parameter acquisition module, and optional passive switch status acquisition module. It can also be combined with on-site temperature sensors, current transformers and Hall sensors to form a set of solutions for precision power distribution cabinets.
3.2 Features
Rich Features
The precision column head cabinet adopts the AMC100 series multi-circuit monitoring device developed by Acrel, which can not only measure the three-phase current, voltage, active power, reactive power, apparent power, power factor, frequency, etc. At the same time, the current, voltage, active power and power factor of multiple branches are monitored. It can display the accumulated active electric energy and incremental electric energy, monitor various parameters of the system operation, and comprehensively display it through the HMI, which reduces the space occupation of the power distribution cabinet and improves the volume ratio of the power distribution cabinet.
Improve safety
In addition to power management, the precision column cabinet also has the functions of operation management and safety management, which improves the reliability of the entire power distribution system and reduces risks area.
Supporting software
Acrel has specially developed the precision power distribution management system software. With this set of management software, users can remotely access the two through the data center background management system to realize electrical parameter values, switch status, neutral ground voltage and leakage current etc. Real-time monitoring of data,it can also realize functions such as over-limit alarm and data upload.
3.3 Application Cases
4 Conclusion
Acrel precision power distribution column cabinet provides power distribution, distribution circuit protection, metering, management and computer grounding services for data center IT equipment and conducts real-time monitoring and operation quality management of the entire power distribution system to help users optimize Network data center. Strengthen energy consumption management, improve server rack operation efficiency, provide reference and technical support for data center energy optimization and adjustment and ultimately achieve the purpose of data center energy saving and consumption reduction.
