question and answer

What is SVG?
SVG stands for Static Var Generator, a high-performance power electronic device used for reactive power compensation, voltage stabilization and harmonic control in power grid systems.
What makes SVG better than traditional capacitor compensation cabinets?
SVG features millisecond-level fast response and stepless bidirectional regulation. It will not amplify harmonics and can maintain stable compensation capacity even when grid voltage drops.
What problems can SVG solve for factories?
It can suppress voltage flicker, stabilize power factor to avoid power factor fines, filter harmonics, balance three-phase current and improve overall power quality.
Where are the main application scenarios of SVG?
It is widely used in metal smelting, welding equipment, new energy photovoltaic/wind power stations, data centers, large shopping malls and industrial parks with impact loads.
Is SVG high in maintenance cost?
No. It adopts modular design without frequently switched contactors. It has low operation loss, long service life and minimal daily maintenance work.

Reasons to adopt Static Var Generator (SVG)

Eliminate voltage flicker from impact loads
Sudden reactive power fluctuations of welders, rolling mills and lifting equipment lead to light flicker and unstable machine operation. SVG completes compensation within milliseconds to stabilize grid voltage.
Maintain high power factor and avoid utility penalties
Conventional capacitor banks only offer stepped compensation, easily causing under or over compensation. SVG provides smooth bidirectional reactive power regulation to keep power factor qualified and cut power surcharge.
Suppress harmonics and three-phase unbalance to protect electrical assets
Rectifiers and inverters generate heavy harmonics which damage capacitors and motors. SVG filters harmonics and balances three-phase current, reducing power loss and extending equipment service life.
Maintain full compensation capacity under low grid voltage
Conventional reactive compensation devices lose output when grid voltage drops. As a current source, SVG can output rated reactive current stably even at low voltage to solve terminal voltage drop problems.
Save space and reduce long-term maintenance cost
SVG features compact modular design with much smaller footprint than capacitor cabinets. It has no frequently switched contactors or aging capacitors, featuring low failure rate and operation loss.
