1 Introduction

In recent years, with the vigorous development of the digital economy, the supporting role of the data center in the new infrastructure system has become increasingly prominent. While enabling the digital transformation of thousands of industries, the huge energy consumption caused by it has also aroused high attention of the society. According to the data released by the Ministry of Ecology and Environment, in 2021, China’s data center electricity consumption accounted for 2.6% of the total social electricity consumption, and carbon emissions accounted for about 1.14% of the national carbon emissions. It is predicted that the social demand for computing power will grow at a rate of more than 20% per year, and the industry’s demand for electricity will also continue to increase.

02 User Requirements

The challenge facing the data industry under rapid development: How to achieve both growth and carbon reduction, but also reduce costs? The expectation of data industry insiders is: carbon control without electricity control. Carbon conrol, that is, make the data center use green electricity as much as possible, while doing a good job of comprehensive energy management, to achieve energy saving and reduce carbon emissions; Non-controlled electricity refers to giving sufficient power supply, and ensuring the quality of electric power in terms of voltage, frequency, etc., and this is also one of the goals of the “East number West calculation” project.

03 Acrel Precision Power distribution head cabinet helps data centers save energy

Since its establishment, Acrel has been committed to smart grid terminals, as a data center participant and energy saving service

provider, Acrel is making efforts in the “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 to achieve the “double carbon” goal, including the launch of the precision distribution head cabinet, for the data center room energy end, Comprehensive collection of all energy data. It provides high-precision measurement data for the terminal energy monitoring system, reflects the power quality data in real time through the display unit, and uploits 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, meeting the requirements of most data centers.

04 application scheme

Acrel precision PDC is composed of HMI touch screen, main access line acquisition and monitoring module, branch electrical parameter acquisition module, and optional passive switch status acquisition module, and can also work with the field temperature sensor, current transformer, Hall sensor, to form a set of solutions for precision PDC.

05 Features introduced

Multifunction

The precision head cabinet adopts the AMC100 series multi-loop monitoring device developed by Acrel, which can measure the three-phase current, voltage, active power, reactive power, apparent power, power factor, frequency, etc. on the incoming line side, and can also monitor the multi-branch current, voltage, active power, and power factor at the same time. At the same time, the accumulated active power and incremental power can be displayed, the parameters of the system operation are monitored, and the HMI integrated display reduces the space occupation of the distribution cabinet and improves the floor area ratio of the distribution cabinet.

Improve safety

In addition to power management, the precision head cabinet also has the function of operation management and safety management, which improves the reliability of the entire distribution system and reduces the risk. The precision head cabinet supports more loops, has high space utilization rate, and reduces the footprint.

Supporting software

Acrel specially developed precision distribution management system software, with this management software, users can remote access to the two through the data center background management system, to achieve real-time monitoring of electrical parameter values, switching status, zero ground voltage and leakage current data; It can also implement functions such as over-the-limit alarm and data upload.

06 Application case

Acrel precision PDC is composed of HMI touch screen, main access line acquisition and monitoring module, branch electrical parameter acquisition module, and optional passive switch status acquisition module, and can also work with the field temperature sensor, current transformer, Hall sensor, to form a set of solutions for precision PDC.
