3~11kV Indoor Water Cooled SVG

(Static  Synchronous  Compensator), also known as SVG (Static Var Generator)    SVG is a chain-type static synchronous compensator (STATCOM/DSTATCOM, also knows as SVG) ?active dynamic reactive and harmonic compensation device at different compensation ranges.     SVG, different from impedance compensation (injecting or absorbing reactive power by capacitor and reactor) theory of traditional SVC, is based on voltage source converter, whose theory is equivalent to static synchronous condenser but whose performance is better than that of condenser and SVC. Especially, its operation range is wide, and its reactive compensation under low voltage is far greater than that of SVC.
