Safe and reliable
- Advanced Static Var Generator (ASVG) is a new type of dynamic reactive power compensation product, combining power factor correction and harmonic mitigation in one unit. It provides the same dynamic performance for compensating reactive power as the SVG with the added benefit of combining harmonic mitigation and controlling three phase unbalance. Advanced static var generators (ASVGs) are high-performance, compact, flexible, modular, and cost effective to provide immediate and efficient responses to power quality problems in high and low voltage power systems.
Working Principle
Advanced Static Var Generator(ASVG)
With external CT detecting the load current in real time, internal DSP calculate and abstract the reactive power and harmonic content of load current, then send the PWM signal to internal IGBT and adjust the phase and amplitude of the output voltage on the AC side of theinverter or directly control the phase and amplitude of the current on the AC side of the inverter, so as to quickly absorb or emit the required reactive power and harmonic current, and realize the purpose of fast dynamic adjustment of reactive power and harmonic compensation.Not only the reactive current of the load , but also the harmonic current can be tracked and compensated.
