Co to jest STATCOM?

A STATCOM is a static syncours generator that can inject or absorb reactive power into an AC power system. It uses a Voltage Source Converter (VSC) to produce a three-faxe voltage athe fundamentaltal frequency. By controling the magnitude andd faxe of this output voltage relativa to the transmissionon line voltage, thee STATCOM can exchange reactive power with the grid. The core contents included a VSC (typicy using IGT), a DCCl caste contribucitok energy store, and a couple transf mer tfore mer.
