STATCOM will be utilized in the night for power factor correction and voltage control at the terminals of an induction motor operating at poor power factor. PV solar farms produce power during the day and are completely idle in the nights. The proposed new control on PV solar system will help in increase the utilization of the PV solar system. A key component of the PV solar plant is a voltage sou...

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...

The ubiquity of synchronous generation should not be assumed in highly renewable power systems. Various problems may consequently arise, not least of which are the difficulties entailed in maintaining regional reactive power balance. Offering a potential solution to such problems, modern renewable generator technologies offer controllable reactive power resources. As many of these generators will ...

STATCOM - Static Synchronous Compensator It is a solid-state switching converter, capable of generating or absorbing independently controllable real and reactive power at its output terminals when it is fed from an energy source. STATCOM is considered as voltage-source converter that, from a given input of dc voltage, produces a set of 3-phase ac-output voltages, each in phase with and coupled to ...

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...
