Static Synchronous Compensator (STATCOM)



•STATCOM stands for Static Synchronous Compensator or Condenser.

•It may be a source of reactive power or sink of reactive AC power.

•It can also provide active power when connected to source of power.

•It is a shunt device which uses power electronics devices like GTO, IGCT, MCT or IGBT etc.

•STATCOM is more advantageous than SVC.

•STATCOM exhibit constant current characteristics.

•STATCOM is usually installed to improve power factor and to improve voltage regulation.

•STATCOM is a voltage source converter device (VSC).

•Basically STATCOM consists of Coupling transformer, Power converter, Reactors and Controllers etc.

•STATCOM have symmetric lead-lag capability.

•STATCOM have no moving part.
