Nexus Hybrid Static Var Generators

Nexus SVGC (Hybrid Var Generator or Compensator) integrate Thyristor Switched Capacitor (TSC) and SVG, modular design, with dynamic compensation functions of reactive power compensation, harmonics compensation, voltage fluctuation, load unbalance. Also, this SVGC has high cost performance, and without overcompensation or under compensation.

Comparing to traditional SVC from economic, technical and performance perspectives, Nexus SVGC use passive capacitor modules coarse tuning firstly, then fine tuning by active SVG module. Nexus SVGC has high reliability, safety and economic, TSC module can continue work when SVG module failure.


Functions & customer benefits

Key functions

  • Ultra-fast reactive current compensation for transient or cyclical loads
