Description

Overview

GAOTek Voltage Control and Reactive Power Management uses insulated gate bipolar transistor (IGBT) to control the magnitude and phase of inverter AC voltage, so as to achieve the purpose of reactive power and harmonic compensation. Because the switching frequency of IGBT is very high (up to dozens of kHz), SVG can compensate rapid reactive loads and achieve quite high compensation accuracy. SVG is the best scheme in the field of reactive power control.

 

Features

  • Reactive power compensation: Cos Φ = 1.00
  • Continuous correction – step less control. SVG controls from 0 – rated kVAR as one continuous range
  • Capacitive and Inductive compensation: -1 to +1
  • Full correction in less than 5ms. Suitable for highly dynamic loads where the power factor fluctuates rapidly or in big steps e.g., sawmills, cranes, welders
  • No overcompensation or under compensation as experienced with capacitor switching systems. Current imbalance correction can correct for load imbalance across all three phases
  • Compact High Performance
  • Wall mount or cabinet mount in an ultra-compact design.
  • Modular design permits 600 kVAR within a single cabinet.
  • Can be incorporated into electrical switchboards
  • Unaffected by harmonic distortion and free from harmonic resonance
  • Unaffected by network voltage drop. Even under reduced network voltage levels full reactive current can be provided to meet working conditions
  • There are no nasty transient voltage spikes caused by the switching of capacitors
  • Presents to the electricity grid as a very high impedance device. Network companies need not worry about the attenuation of ripple injection signals
