50-800kvar Static Var Generator(SVG) for Power Factor Correction(PFC)

Static Var Generator(SVG) is a new generation of dynamic var compensation device based on fully controlled IGBT (Insulated Gate Bipolar Transistor) devices. Leveraging a PWM inverter, it delivers millisecond-level response speed to dynamically generate required reactive power, enabling precise bidirectional compensation for inductive or capacitive loads. This significantly improves the power grid’s power factor (typically to over 0.95) and reduces line losses. Meanwhile, SVG effectively suppresses harmonics (up to the 50th order) and mitigates three-phase unbalance, providing comprehensive power quality improvement. As an essential solution for stable grid operation, it is widely applied in industries, renewable energy integration, and other sectors.
