SVG Static Var Generator PFC Series

Générateur VAR statique SVG is a product aimed at Power Factor Correction and Harmonic Filtering along with Three-phase balancing Function. Benefiting from inverter technology, the SVG Static Var Generator PFC series’ compensation is steplessly, which means SVG output shall match the system reactive power, with no over-compensation or under-compensation. For a single module, SVG capacity ranges from 30kvar to 100kvar. For cabinet system, it’s unlimited parallel design. When the load is generating inductive or capacitive current, it makes load current lag or leads to the voltage. SVG detects the phase angle difference and generates leading or lagging current into the grid, making the phase angle of current almost the same as that of voltage on the transformer side, which means the fundamental power factor is unity.

5. How CoEpower Static Var Generator works

When the load is generating inductive or capacitive current, it makes load current lag or lead the voltage. SVG detects the phase angle difference and generates leading or lagging current into the grid, making the phase angle of current almost the same as that of voltage on the transformer side, which means the fundamental power factor is unity.

6. Compensation effect

IGBT DSP control system makes the reactive power compensation from mechanical compensation evolve to intelligent power electronic stability compensation. Whatever the load current changes, SVG can always output the corresponding compensation current to realize the perfect combination. Always keep the power factor as 0.99. Running well in a severe environment like high THDU/high ambient temperature/high amplitude.
