Advanced Static Var Generator (ASVG)
Product Summary:
Advanced static var generator (ASVG),is a new type of dynamic reactive power compensation product, which is the representative of the latest technology application in the field of reactive power compensation. By adjusting the phase and amplitude of the output voltage on the AC side of the inverter, or directly controlling the current on the AC side of the inverter Amplitude and phase, 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 can be tracked and compensated, but also the harmonic current can be tracked and compensated. Enhanced 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. They improve power quality, extend equipment life and reduce energy losses..
Working Principle:
External CT detects 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, adjust the phase and amplitude of the output voltage on the AC side of the inverter or directly control the phase and amplitude of the current on the AC side of the inverter. 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 can be tracked and compensated, but also the harmonic current can be tracked and compensated.
