Project Introduction
The China Unicom South China (Dongguan) Data Center is located in the national high-tech industrial zone. The data center is designed and built according to the international T3+ standards, covering a total area of 91.8 acres with a building area of 131,900 square meters. The complex includes the IDC server room building, power center, underground water storage pool, customer service call center, research and development center, and training center building.
Analysis and Solution
The main load in the data center is the UPS, which is the primary source of harmonics, generating the 11th and 13th harmonics. Additionally, lighting and variable frequency air conditioning also contribute to harmonic generation. Harmonic currents in the system can affect power distribution and electrical safety, as well as interfere with the normal operation of communication equipment in the data center. To mitigate the harmonics and improve power quality, the project utilizes our company’s 3200A Active Harmonic Filter for harmonic treatment.
Performance
THDi Before Mitigation 17.3%
THDi After Mitigation 4.7%
After the equipment was put into operation, the harmonic current distortion rate was reduced from 17.3% to 4.7%. The harmonic mitigation effect has been excellent, effectively treating the harmonic currents in the power distribution system, improving power quality, reducing line losses, and ensuring the stable operation of both the distribution and production equipment.
