Does PV inverters have to use SVG

6 FAQs about [Does PV inverters have to use SVG ]

What is SVG static VAR generator?

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

How does SVG work?

It has the same operating principle as an active filter; the SVG injects a current in the opposite direction to counteract the installation’s non-useful power (inductive and capacitive), thus ensuring that the target cosϕ is achieved. √ Compesation without stages,Instant compensaton.

Why should we use SVG reactive power compensation devices?

Therefore, it is even more necessary to use SVG reactive power compensation devices reasonably to improve the transmission stability and capacity of the new power system, avoid voltage fluctuations and harm, and ensure low harmonic content, fast response speed, and high reliability in the output of photovoltaic power plants.

What is the principle of SVG?

The principle of the SVG is very similar to that of Active Power Filter, as demonstrated in the picture below. When the load is generating inductive or capacitive current, it makes load current lagging or leading the voltage.

Can SVG be installed on a wall?

Delta’s Wall-mounted SVG can be installed on a wall, which is suitable for low rating applications, and wall-mounted type HMI can be installed on the wall-mounted SVG module, along with a mounting bracket to provide support and protection. Delta can supply IP30, IP42, IP54 or customized solutions.

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.
