Compensate Reactive Power from 3kV - 35kV

Ikonmac high-voltage Static Var Generator (SVG) system for industrial and grid-scale reactive power compensation

SVG PRINCIPLE

SVG adopts a cascaded multi-level H-bridge power unit configuration, utilizing turn-off capable high-power power electronic devices (such as IGBTs) to form a self-commutated bridge circuit. It is connected in parallel to the power grid through a reactor (or step-up transformer). By appropriately adjusting the amplitude and phase of the AC-side output voltage of the bridge circuit or directly controlling the AC-side current, the system can absorb or generate reactive current that meets grid requirements, achieving dynamic reactive power compensation.
