Product Description

Static Var Generator (SVG) is a product aimed for Power Factor Correction, Voltage Regulation along with Three-phase Balancing Function. SHHKK-SVG can do bi-directional power factor correction, PF from 1.0 inductive to 1.0 capacitive. Benefiting from inverter technology, SVG compensation is stepless, which means SVG output shall match the system reactive power, no over-compensation or under compensation. For single module, SVG capacity ranges from 35kvar to 150kvar. For cabinet system, it's unlimited parallel design . Compared with the traditional capacitor bank, SVG has the advantages of fast response and highcompensation accuracy without under-compensation or over-compensation problems.Δ Improved power factor PF ≥ 0.99Δ Compensated inductive or capacitive reactiveΔ Unaffected by harmonics

HKK-SVG static var generator is a bridge converter composed of fully controlled power electronic devices for dynamic reactive compensation. The basic principle is that the load current is detected in real time by the external current transformer (CT), and the reactive content of load current is extracted by the internal DSP computing. Finally, the instruction value is calculated to control the PWM signal generator to send the control signal to the internal IGBT, so that the inverter can produce the reactive compensation current to meet the requirement, and finally realize the dynamic reactive compensation.
