STATCOMs

Static Synchronous Compensators

High-Performance STATCOM for industrial, renewable, and utility applications

Our modular STATCOM (Static Synchronous Compensator) provides real-time reactive power compensation and dynamic voltage support for demanding industrial environments such as steel plants, mining operations, data centers, and renewable energy systems.

Engineered to handle severe power disturbances and rapidly changing loads, it delivers ultra-fast response and precise voltage and power factor control.

Key Benefits:

  1. Instant voltage stabilization (response time <5 ms)
  2. Flicker mitigation
  3. Unity power factor under variable load conditions
  4. Improved power quality through harmonic reduction
  5. Avoids utility penalties by enhancing voltage and reactive profiles
  6. Scalable modular design (2 Mvar to 200+ Mvar)
  7. Available in indoor, outdoor, containerized, or building-mounted configurations
  8. Superior alternative to multi-stage harmonic filters, offering better performance and flexibility
  9. Cost-effective replacement for SVC upgrades, with lower CAPEX and a reduced footprint
  10. Backed by Southern States' 24/7 after-sales support and long-life engineering
