With growing mature of control system and gradual reduction of cost

SVG

as the most advanced dynamic reactive power compensation method

is used widely in industrial and mining enterprises. In this paper

the principle

selection calculation and application of SVG is described with the wire rod rolling mill as an example. It is shown by the practice that application of SVG in industrial and mining enterprises can improve significantly system power factor

provide wider reactive power range

better harmonic feature and fast response of system

which not only brings remarkable economy efficiency

but also has good development prospective.
