SFR-SVG is a new generation of static reactive power compensation device (short as SVG) product, and it represents latest technical application in the reactive power compensation. SVG is connected in a parallel way in power grid, and is equivalent to a changeable reactive current source, and its reactive current can be controlled flexibly to automatically compensate reactive power required by the system. In one hand, it solves the switching compensation problem of parallel connection capacitors of harmonic reactive disturbance effectively; on the other hand, it can suppress or treat harmonic distortion according to the actual requirements of the user, thus cleaning the power grid environment.
