Product Description

Static Var Generator:ZD-SVGM Series

The  static var generator (SVG for short), based on voltage type inverter principle, uses the isolated gate binary transistor (IGBT4) to control the value and phase of AC voltage of inverter, so as to serve the purpose of reactive and harmonic compensation. As the switching frequency of IGBT is very high (dozens of kHz), SVG can realize fast compensation for reactive load, and achieve very high compensation precision. ASVG is currently the best solution in reactive power control filed. Compared with the traditional SVT represented by TSC, the regulation speed of SVG is faster (the response speed is within 5ms), its compensation precision is high (the power factor after compensation is 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.
