SVG vs. SVC
11/18/2025 07:31:58
Technology Evolution
In the field of reactive power compensation, traditional SVC (Static Var Compensator) were once widely used. However, with advancements in power electronics, the SVG (Static Var Generator) has emerged as the undeniable next-generation benchmark. Why?
Comparative Analysis
| Comparison Item | Traditional SVC (e.g., TSC, TCR) | Modern SVG | Our Advantage |
| Response Speed | 10-40ms | ≤5ms | 2-8x faster, effortlessly handles impact loads. |
| Compensation Accuracy | Step-wise compensation, with gaps. | Smooth, stepless, and precise control. | Superior voltage stability, no over/under-compensation. |
| System Resonance | Uses capacitors/reactors, prone to system resonance. | Inherently immune to resonance, a resonance killer. | Enhanced safety, no risk of harmonic amplification. |
| Low-Voltage Performance | Output drops quadratically with voltage—weakest when most needed. | Can provide full rated output even during voltage dips. | Unmatched reliability, ensures performance during critical faults. |
| Footprint & Noise | Requires large capacitors/reactors, bulky and noisy. | Compact IGBT-based design, 1/3 smaller size, quiet operation. | Saves space, ideal for indoor and noise-sensitive environments. |
Conclusion
With its overwhelming advantages in speed, stability, safety, and size, the SVG is comprehensively replacing SVC as the preferred choice for reactive power compensation in wind farms, PV plants, arc furnaces, and automotive manufacturing.
