LSVG Module Type Static Var Generator(SVG /STATCOM)

SVG is the representative of latest technology in the present reactive power compensation field. SVG is connected

to the power grid, acting as a variable reactive current source. Its reactive current may rapidly track variation of

load reactive current and automatically compensate reactive power required by the system. Because SVG

responds very fast, it's also called static synchronous compensator (short for STATCOM).

Basic principle of static var generator: connect the auto phase commutating bridge circuit to the power grid via

reactor, properly regulate phase and amplitude of output voltage in the AC side of bridge circuit or directly control

current in the AC side so that the circuit may absorb or generate the compliance reactive current to realize reactive

compensation in a dynamic manner. In the meantime, it can inhibit voltage flicker, keep it stable, track and

compensate harmonic current, absorb several low order harmonics of power distribution system and balance

inter-phase reactive power.
