Solution Overview
1. Severe Power Quality Challenges Faced by Modern IDC
- Severe harmonic pollution : Servers and UPS generate 3rd, 5th, 7th, 11th, 13th high-order harmonics, leading to neutral line overheating, transformer extra loss, cable insulation aging, breaker misoperation, and even fire hazards; harmonic distortion disturbs precision server chips, triggering data packet loss, calculation errors and service interruption.
- Fluctuating power factor & high reactive power penalty : Dynamic startup/shutdown of IT clusters and cooling loads causes sharp reactive power swings. Low power factor below 0.9 will incur heavy reactive electricity surcharges, raise overall PUE and increase operating costs.
- Three-phase current unbalance : Uneven distribution of single-phase server loads results in zero-sequence current accumulation, reducing transformer effective transmission capacity and shortening the service life of power distribution equipment.
- Voltage flicker & resonance risk : Traditional capacitor compensation cabinets easily trigger parallel harmonic resonance, amplifying distortion and damaging UPS and storage power modules.
