Statcom2

STATCOM (Synchronous Static Compensator) is a regulating device used in AC electricity transmission systems, based on IGBT technology, with a vectoral control strategy for the generation of reactive energy.

It can generate both capacitive and inductive reactive current.. 

  

 

 

 

 


General characteristics

  • Voltage regulation.
  • Power factor regulation.
  • Accurate and continuous dynamic reactive power compensation (leading or lagging).
  • Fast dynamic response time.
  • Smooth response – no voltage distortion.
  • No resonance risk – valid for weak electric grids. Parallel connection.
  • Modular construction – redundancy and improved availability of the converter.
  • Up to 9MVAR in a standard 40-foot container. Controllability of up to 5 external capacitor banks or reactors, fulfilling a wide range of reactive power compensation (both capacitive or inductive).
