FGI's Static Var Generator (SVG) continues to provide reliable solutions across a wide range of industrial scenarios. From ferroalloy production to renewable energy integration, FGI SVG ensures stable voltage, improved power factor, and compliance with national power quality standards. Below are three newly implemented SVG application cases across China.
Case 1: Ferroalloy Furnace Application in Zhengzhou, Henan
Location: Zhengzhou City, Henan Province
Compensation Capacity: -2000kvar to +2000kvar
System Voltage: 6kV
Load Characteristics:
Compared to arc furnaces, ferroalloy (submerged arc) furnaces are more stable. However, the site encountered serious three-phase load imbalance and a low power factor.
Compensation Results:
-
Significant reduction in three-phase imbalance
-
Power factor improved to meet utility requirements
-
Stable operation of the furnace under optimized power conditions
Case 2: Wind Power Station Application in Yantai, Shandong
Location: Yantai City, Shandong Province
Compensation Capacity: -10000kvar to +10000kvar
System Voltage: 35kV
Load Characteristics:
Due to the intermittent nature of wind resources, the system suffered from frequent voltage fluctuations, with instantaneous power factor dropping as low as 0.81.
Compensation Results:
-
System voltage stabilized within 35.5–35.7kV
-
Meets national standard GB/T 12325-2008 (Voltage Deviation Assessment)
-
Real-time power factor raised to 0.96
-
Complies with GB/T 14549-1993 (Harmonics in Public Power Grid)
-
Supports Low Voltage Ride-Through (LVRT) requirements
Case 3: Induction Furnace Application in Xuzhou, Jiangsu
Location: Xuzhou City, Jiangsu Province
Compensation Capacity: -4000kvar to +4000kvar
System Voltage: 6kV
Load Characteristics:
The load exhibits a wide frequency spectrum with serious harmonic current distortion, especially at the 5th, 7th, 11th, and 13th orders.
Compensation Results:
-
Harmonic current compensation efficiency up to 70% below 19th order
-
5th, 7th, 11th, and 13th harmonic currents reduced to meet national standard
-
Complies with GB/T 14549-1993 (Harmonics in Public Power Grid)
Conclusion
FGI SVG solutions demonstrate outstanding performance in tackling real-world grid challenges — from harmonic mitigation and power factor correction to voltage stabilization and LVRT compliance. Whether in renewable energy or heavy industry, FGI ensures that power systems remain efficient, reliable, and compliant.
