Svg/statcom static var generator avoiding penalty and saving electricity bills

Description

The  static var generator based on voltage type inverter principle,uses IGBT to control the value and phase of AC voltage of inverter, so as to serve the purpose of reactive and harmonic compensation. SVG can realize fast compensation for reactive load, and achieve very high compensation precision.

SVG is currently the best solution in reactive power control filed. SVG is faster (within 10ms), its compensation precision is high (power factor over 0.99), the compensation method is flexible (SVG can compensate both inductive reactive power and capacitive reactive power), and SVG also has the function of active filtration of harmonic current.
