HYSVG Static Var Generator (SVG)

The HYSVG static var generator provides continuous inductive and capacitive reactive-current compensation for low-voltage distribution networks. It responds to changing loads without capacitor switching transients, helping stabilize voltage, improve power factor, reduce network losses and correct current imbalance in industrial facilities and commercial power systems.

Product Features

  • Provides fast and continuous reactive power compensation to maintain stable system voltage.
  • Improves power factor and reduces system losses by supplying inductive or capacitive reactive current in real time.
  • Mitigates voltage fluctuations, current distortion, and load imbalance caused by nonlinear or impact loads.
  • Uses full-digital control with high sampling accuracy, ensuring stable operation under varying grid conditions.
  • Offers rapid dynamic response, enabling precise real-time compensation without switching transients or inrush currents.
  • Supports modular parallel configuration to increase overall compensation capacity.
  • Integrates comprehensive protections including overvoltage, undervoltage, overcurrent, overload, overheating, short circuit, and communication failure.
  • Provides detailed monitoring and data logging for voltage, current, power factor, reactive power, harmonics, frequency, and device operating status.
  • Designed for stable long-term operation with high reliability and minimal maintenance requirements.

Application Fields

  • Industrial lifting equipment, cranes, and heavy-duty hoisting systems with typical impact loads requiring stable voltage and improved power factor.
  • Power distribution systems supplying variable-speed drives, welding machines, compressors, pumps, and large impact loads.
  • Mining, petroleum, drilling, and construction machinery with rapidly changing load demands or severe reactive power fluctuations.
  • Manufacturing facilities with large-scale automation equipment, PLC systems, CNC machines, and precision electronic devices sensitive to voltage variations.
  • Data centers and communication stations requiring stable reactive power support and improved power quality.
  • Commercial buildings, hospitals, laboratories, and public facilities with complex loads causing voltage drop, imbalance, or reactive instability.
  • Any distribution network where rapid dynamic reactive compensation is needed to improve efficiency, reduce energy loss, and enhance equipment lifetime.
