SDG(SVG) Dynamic Compensation Module

Static Var Generator (SVG:Static Var Generator) is a new generation of compensation device with power electronic devices as the core, which can replace the traditional capacitor compensation technology products, and make up for the traditional capacitor compensation group switching, can only compensate for the inductive load and other inherent shortcomings. Stepless output reactive power, accurately set the ideal compensation mode. Dynamic two-way adjustment of power factors, with fast switching speed, small size, low loss, reliable operation and other characteristics, from the machine theory to avoid the occurrence of resonance.

Product Description

Static Var Generator (SVG:Static Var Generator) is a new generation of compensation device with power electronic devices as the core, which can replace the traditional capacitor compensation technology products, and make up for the traditional capacitor compensation group switching, can only compensate for the inductive load and other inherent shortcomings. Stepless output reactive power, accurately set the ideal compensation mode. Dynamic two-way adjustment of power factors, with fast switching speed, small size, low loss, reliable operation and other characteristics, from the machine theory to avoid the occurrence of resonance.

 

Technical features
(1) faster response speed: ≤ 5ms.

(2) higher security: there is no possibility of resonance with the system impedance, more security.
(3) Compensation function diversification using the same set of SVG device, you can achieve a variety of different compensation functions:

  • Compensate load reactive power;
  • Compensating load harmonics;
  • Compensates for load imbalance;
  • At the same time compensate load reactive, harmonic and unbalance.

(4) Very low harmonic content SVG adopts PWM technology and multiple technology. Compared with TCR SVC, the harmonic content is very low and will not cause secondary pollution to the power grid.
(5) Small footprint: Since there is no need for large-capacity capacitors and reactors as energy storage components, the footprint of SVG is only 50% of the same capacity SVC.
