Advanced Static Var Generator ASVG
Advanced Static Var Generator (ASVG)
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.
Product Features
- Reactive power compensation: Cos Ø = 1.00
- Capacitive and Inductive compensation: -1 to +1
- All the features and benefits of the SVG. – Mitigation of 3rd, 5th, 7th, 9th, 11th harmonic orders
- Unit capacity can be selected in any proportion between power factor correction and harmonics correction
- Capacitive inductive load-1~1
- Current unbalance correction can correct for load unbalance across all three phases
Working Principle
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 the inverter 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.
