SINEXCEL Advanced Static Var Generator

 

1. Working principle


Sinexcel Advanced Static Var Generator (ASVG) conducts real-time monitoring to load current through external Current Transformer (CT) and detects reactive components and harmonic from load current through the calculation of internal Digital Signal Processor (DSP) , then transmits PWM signal to internal Insulated Gate Bipolar Transistor (IGBT). Conforming reactive current and low-order harmonic current are generated by inverter with control settings to achieve reactive compensation and control harmonic.

2. Advantage

“One-stop” General Compensation Technique

Power factor, Three-phase unbalanced and Low-order harmonic synchronization control

  • Power factor correction & Three-phase balancing
  • Support low-order (3, 5, 7, 9, 11 13 orders) harmonic compensation (≤50% rated capacity)

Resonance avoidance

  • ASVG is a current source device which avoids resonance phenomena in mechanism.

Excellent harmonic characteristics

  • No harmonic is generated, no harmonic is amplified and the odd harmonic orders lower than 13th can be filtered.

Stepless adjustment

  • ASVG can realize dynamic stepless power factor correction without over-compensation and under-compensation.

Modularized product design

  • ASVG adopts modular product design and cabinet installation.
