Power Quality Control Scheme for Data Center

Project Introduction

With the rapid development of the communication industry, the scale of the data center is also growing day by day, and the supporting power supply equipment is also expanding continuously and becoming too concentrated. A mobile branch uses multiple sets of UPS and switching power supply systems, which are typical three-phase nonlinear loads. These nonlinear equipment will generate a large number of harmonics during use, resulting in distortion of voltage and current waveforms and seriously affecting the power supply safety of the computer room.

Project Scheme

In order to eliminate hidden dangers in the power supply and improve the safety and reliability of AC power supply for comprehensive buildings, an active power filter shall be adopted according to on-site measurement conditions and considering that there are many types of harmonic waves generated.

Application Effects

 

                                                                              Current Spectrum before Treatment                  Current Spectrum after Treatment 

It can be seen from the figure that the total harmonic content before compensation is 58.2%, and the total harmonic content after compensation decreases to 5.4%; The 5th harmonic drops from 50.7% before compensation to 5.4% after compensation; It can be seen that after the filter is put into operation, the system harmonic has been well suppressed, which improves the power supply reliability of the power supply system, eliminates the hidden danger of the influence of system harmonic on the communication system, and receives good results.

Customer Benefits

With the digital development of society, data center has become a top priority. It drives all walks of life forward without any mistakes. Therefore, the data center has a high requirement for the reliability of the distribution system. The active power filter is used to comprehensively manage and optimize the power quality of the distribution system, so as to ensure the safe, efficient, reliable and stable operation of its distribution system and escort the mission of scientific and technological development undertaken by the data center.
