Product Overview
💡
Static Var Generator (SVG) is a core member of FACTS equipment. Utilizing a dual digital signal processor (DSP) core, it connects a self-commutated bridge circuit in parallel to the power grid through a reactor. By adopting real-time data acquisition and dynamic tracking, it continuously monitors grid voltage and current.
The system quickly and continuously compensates for reactive power, significantly improving power quality at the connection point. It helps overcome three-phase imbalance, eliminates voltage flicker, and suppresses harmonic pollution.
