High-Speed Static Var Generator (SVG) — Reactive Power Compensation for Industrial Grids

High-Speed Static Var Generator (SVG) — Reactive Power Compensation for Industrial Grids

The JYINS High-Speed Static Var Generator (SVG) delivers real-time reactive power compensation for industrial and commercial power systems. Using advanced IGBT-based power electronics, it dynamically corrects power factor, suppresses harmonics, and stabilizes voltage fluctuations within microseconds. Available in modular configurations from 50kVar to 500kVar, the SVG is the modern replacement for traditional capacitor banks, offering faster response, wider compensation range, and zero resonance risk.

Frequently Asked Questions (FAQ)

Q: How is SVG different from traditional capacitor banks?

A: SVG uses active power electronics to dynamically compensate reactive power in real-time (<5ms), while capacitor banks switch steps slowly and can cause resonance. SVG also handles both inductive and capacitive loads continuously.

Q: What voltage levels does it support?

A: Standard models cover 220V–690V three-phase systems. Higher voltage applications available with step-up transformers.

Q: Can multiple units operate in parallel?

A: Yes, JYSVG modules can be paralleled for higher capacity. Master-slave control ensures coordinated compensation.

Q: Does it require regular maintenance?

A: SVG is solid-state with no mechanical switching parts. Annual inspection of filters and fans is recommended; no capacitor replacement needed.
