Static Var Generator (SVG)—Single Phase (2)

Static Var Generator (SVG)—Single Phase (3)

Hazards of excessive reactive power

Static Var Generator (SVG)—Single Phase (1)

When the device is started or shut down, the voltage of the regional power grid plummets, fluctuates, and flashes

Static Var Generator (SVG)—Single Phase (7)

The active power output of the generator is reduced, its own loss is increased, and its life is shortened

Static Var Generator (SVG)—Single Phase (11)

The total current increases, and the equipment and line loss increases

electrical equipment low power factor operation, electrical equipment capacity can not be fully utilized

The principle of the SVG is very similar to that of Active Power Filter, When the load is generating inductive or capacitive current, it makes load current lagging or leading 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 fundamental power factor is unit. YIY-SVG is also capable of correcting load imbalance.
