    Hybrid Dynamic Power Factor Correction Panel - Clariant ...
    Static Var Generators (SVGs) provide instantaneous, precise, dynamic power factor correction (PFC) by using power electronics (IGBTs) to generate or absorb reactive power within milliseconds, achieving unity power factor (>0.99). Unlike passive capacitor banks, SVGs prevent over/under compensation, handle rapid load changes (e.g., cranes, welders), and mitigate harmonics. 
    Key Aspects of Dynamic PFC using SVG 
    • Rapid Response Time: SVGs operate with a reaction time of less than 50
      μmu
      𝜇
      s and a complete response time of less than 15 ms, essential for highly dynamic loads.       
    • Continuous Compensation: They offer stepless, continuous regulation (both inductive and capacitive) without the switching shocks of capacitors. 
    • Operating Principle: SVG monitors load current in real-time, calculates required reactive power, and uses a self-commutated inverter to inject compensating current, acting as a controlled reactive current source. 
    • Elimination of Resonance: Since SVGs do not require passive capacitors for compensation, they avoid resonance issues commonly found with capacitor banks. 
    • Key Applications: Used in industries with rapidly changing loads:
      • Welding equipment and electric arc furnaces.
      • Elevators, cranes, and mining equipment.
      • Renewable energy systems (solar/wind).
      • Data centers, hospitals, and high-rise buildings. 
    Benefits of SVG in Power Factor Correction 
    • Perfecting Power Factor: Boosts power factor to near 1.0 (unity).
    • Enhanced Stability: Suppresses three-phase current imbalance, boosting grid stability.
    • Energy Efficiency: Reduces transformer losses and cable heating by correcting reactive power at the source.
    • Long-Lasting: Low maintenance due to the absence of worn-out mechanical switching components.
