Products Description
Static Var Generator/SVG/STATCOM
Static var generator/SVG/STATCOM is the new standard in reactive energy compensation. This power electronic current source is the accurate and highly reliable solution for today’s networks characterised by significant increase in harmonics, voltage variations caused by intermittent renewable sources connected to the network and voltage level due to the smart grid development. The DSP controlled IGBT topology enables a perfect compensation on each phase for both inductive and capacitive loads. It also correct phase unbalance where necessary. Immune to harmonics, resonance and voltage level, it offers a maintenance free solution reusable in any network configuration.
SVG Principle
ZDDQ Static var generator/SVG/STATCOM (SVG for short), based on voltage type inverter principle, uses the isolated gate binary transistor (IGBT) 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.
ZDDQ SVG is currently the best solution in reactive power control filed. Compared with the traditional SVC 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.
