Jiangsu Mobile Suzhou Branch
Typical case of harmonic control of communication equipment room (Jiangsu Mobile Suzhou Branch) Background of the project: With the rapid development of the communication industry, the scale of communication power systems has also grown, and power supply equipment has been too concentrated due to continuous expansion. A mobile branch uses multiple sets of UPS and switching power supply systems. UPS and switching power supplies are typical three-phase non-linear loads. These non-linear devices generate a large number of harmonics during use, resulting in voltage and current waveforms. Distortion has occurred, which seriously affects the safety of power supply in the equipment room.
