Reactive power is necessary to generate magnetic fields, e.g. in motors, transformers and generators. This power oscillates between the source and the load and represents an additional loading. Static var Compensator (SVC) and static var generator can suppress the voltage fluctuation, flicker and rapidly compensate the reactive power and the quality of electric power can be improved. If you have q...

SVG Principle The principle of the SVG is, 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. Compare...

There are a couple of principles to achieve reactive power compensation. The simplest solution is without any doubts a combination of switched passive elements, i.e. switched capacitors and inductors. Figure 1 shows qualitatively the reactive current versus connected voltage of such a solution. The reactive current depends linearly on the grid voltage and as a consequence the reactive power change...

STATCOM A static synchronous compensator, known as a STATCOM, is another device used to regulate the power factor in medium to high voltage applications. They operate on roughly the same principles as a synchronous compensator, however, use a voltage source converter as opposed to a rotating machine to provide dynamic Power Factor Correction. STATCOMs use IGBT switching te...
