SVG (static var generator)
SVG short for static var generator is one of the most advanced power factor correction technique.
The fundamental is applying in high power electronic device (IGBT) to form self-commutation bridge circuit, via reactors in parallel on the grid, the circuit is to absorb or meet the requirements of relative circuit to realize the dynamic reactive compensation.
SVG technology advantage
Compare with using passive device (capacitor) reactive power compensation system, the advantage of SVG as bellow:
● stepless regulation SVG real-time dynamic stepless regulation, which can avoid over and lack problem of compensation
● transient response SVG quickly response speed, its less than 1ms.
● full compensation compensation capacitance, inductive reactive power, COSφ is close 1.0, compensation harmonic, three phase load imbalance.
● safe and energy saving avoid resonance, system harmonic and voltage fluctuations and flicker, reduce electromagnetic noise and power consumption, power saving effect obviously.
● easy installation SVG is adopting modular design, small volume, all east to install.
