Advanced Static Var Generator ASVG50/70/100/150KVAR

Production Description

HKK-ASVG advanced static var generator can detect the load current in real time through the external current transformer(CT), extract the reactive content and harmonic component in the load current through the internal DSP computing, finally calculate the instruction value to control the PWM signal generator to send the control signal to the internal lGBT, and generate the reactive compensation current and harmonic compensation current through the inverter to meet the requirements, so as to achieve the purpose of reactive compensation and harmonic control.
1.Reactive compensation products that take into account harmonic compensation
Main compensation capacitive and inductive reactive
Support low-time(3,5,7,9,11)small-capacity(rated capacity 50) harmonic compensation
2.Safe and excellent reactive compensation effect
HKK-ASVG realizes real-time dynamic stepless adjustment with overcompensation and under compensation
HKK-ASVG is a controllable current active device, which avoids the phenomenon of resonance in mechanism without generating harmonics, without amplifying harmonics and simultaneously filtering out 11 times or less odd harmonics.

Working principle

HKK-ASVG advanced static var generator can detect the load current in real time through the external current transformer(CT), extract the reactive content and harmonic component in the load current through the internal DSP computing, finally calculate the instruction value to control the PWM signal generator to send the control signal to the internal 1GBT, and generate the rea ctive
compensation current and harmonic compensation curent through the inverter to meet the reouirements, so as to achieve the purpose of reactive compensation and harmonic control
