6 FAQs about [Svg voltage inverter]

What is a SVG inverter?

The SVG utilises a high speed three level inverter that reacts to changes in reactive power, exchanging corrective reactive power into the system. Full correction is made in 3/4 of a cycle. This rapid response provides stable accurate real-time power factor correction without the drawbacks of traditional capacitor based systems. Key functions:

What is SVG static VAR generator?

The SVG Static Var Generator is an electronic reactive power compensation system, for both capacitive and inductive power.

Why is SVG used for voltage control?

This advantage makes SVG have great advantages when it is used for voltage control. The lower the system voltage, the more dynamic reactive power regulation voltage is required. SVG has good low-voltage characteristics, and the output reactive current has no relationship with the system voltage.

Is SVG a controllable constant current source?

The lower the system voltage, the more dynamic reactive power regulation voltage is required. SVG has good low-voltage characteristics, and the output reactive current has no relationship with the system voltage. It can be regarded as a controllable constant current source.

How does SVG work if a load is generating inductive or capacitive current?

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.

Does SVG static VAR generator matching capacitor need a filter bank?

When the system voltage fluctuates greatly, the compensation effect is greatly affected and the operation loss is large, SVG static var generator matching capacitor does not need to be equipped with filter bank, and there is no resonance amplification phenomenon.
